[15] Fig.1 illustrates a system 10 configured to issue the subject of the 12 indications of consciously altering one or more parameters of the breathing for breath of the subject 12. To facilitate the issuance of the subject 12 to the instructions to change one or more parameters of the respiration, the system 10 delivers the flow of breathable gas under pressure in the airway of subject 12. The system 10 performs the setting of one or more gas parameters of gas in the flow of breathable gas under pressure for the purpose of issuing control signals to the breathing of subject 12 that motivate the subject 12 to consciously adjust the breath so that it changes one or more parameters of the respiration. Control signals of the breath that is given to the subject 12, give the subject 12 �a burying this guy to change one or more parameters of the respiration with a view to their harmonization with the mode of breathing. The mode of breathing may include, for example, the period with a high volume of inhalation and/or with a reduced rate of breathing, yoga breathing, breathing meditation, breathing mode for use during aerobic and/or anaerobic exercise, Lamaze breathing, the breathing mode for use during therapy with pressure support and/or other modes of breathing. The system 10 is also configured to issue the subject of 12 information relating to the control signals of the breathing delivered (or to be delivered) to the system 10 by a flow of breathable gas under pressure. This information may be provided to the user via audio, visual, tactile and/or through some other sensory feedback. Information relating to the control signals of breathing, can teach the subject 12 to the understanding of the control signals of the breath delivered by a flow of breathable gas under pressure. In one of the embodiments, the system 10 may include a device 14, electronic storage device 16, the user interface 18, one or more sensors 20, a processor 22 and/or other components.

[16] In one of embodiments, the device 14 includes a device to maintain positive pressure. The device supports�ing positive pressure is well known and described, for example, in U.S. patent 6105575, hereby incorporated herein in its entirety. In this embodiment of the device 14 is configured to deliver the flow of breathable gas under pressure in the airway of subject 12.

[17] the Device 14 can be configured to create a flow under a positive pressure of breathable gas in accordance with one or more modes. A non-limiting example of such a regime is continuous positive airway pressure (CPAP). CPAP has been used for many years, and it is confirmed that it is useful in promoting proper breathing. Another mode of creating a flow of breathable gas under pressure is inspiratory positive air pressure (IPAP). One example of a mode IPAP is a bi-level positive air pressure (BiPAP). When using BiPAP patient is given two-level positive air pressure (HI and LO). It is also planned and other modes to generate a flow of positive pressure of breathable gas.

[18] Typically, the time intervals of pressure levels HI and LO are adjusted so that the air level positive pressure of HI is delivered to subject 12 during inhalation of air and the level of positive pressure delivered LO sub�KTU 12 during exhalation. In the conventional system maintain a positive pressure time intervals HI and LO pressure levels are coordinated so that they coincide with the breathing of subject 12 based on the detection of the gas parameters that indicate inhales or exhales the user at the current time.

[19] the Flow under positive pressure of breathable gas delivered to the airway of subject 12 via the interface of the subject 24. The subject's interface 24 configured to provide a flow of breathable gas under pressure generated by the device 14, in the airway of subject 12. Accordingly, the subject's interface 24 includes a duct 26 and an interface unit 28. The duct passes a flow of breathable gas under pressure to the interface device 28, and an interface unit 28 delivers the flow of breathable gas under pressure in the airway of subject 12. Some examples of interface devices 28 may include, for example, endotracheal tube, nasal cannula, tracheotomies tube, a nasal mask, nasal/oral mask, full face mask, obdelavo mask or other interface devices that enable communication flow of gas from the airway of the subject. The present invention is not limited to these Prim�Rami, and involves the delivery of a flow of breathable gas under pressure to the subject 12 using an arbitrary subject's interface.

[20] In one of the embodiments, an electronic storage device 16 contains an electronic information carrier on which information is stored in electronic form. Electronic media electronic storage device 16 may include any data storage system, implemented integrally (i.e., essentially non-removable) with system 10 and/or removable data storage that can be connected to the system 10, for example, through a port (e.g., port USB, port high-speed serial bus (firewire), etc.) or a drive (e.g., disk drive, etc.), or may include both. Electronic storage device 16 may include one or more carriers from among optically readable media (e.g., optical discs, etc.), magnetically readable storage media (e.g., magnetic tape, magnetic hard disk drives, floppy disks, etc.) based on the electric charge storage media (e.g., EEPROM, RAM, etc.), solid-state storage devices (e.g., flash drive, etc.), and/or other electronically readable storage media.On the electronic storage device 16 may store software algorithms, information determined by the processor 22, the information accepted via the user interface 18, and/or other information that ensures the correct functioning of the system 10. Electronic storage device 16 may be a (fully or in part) a separate component within system 10, or electronic storage device 16 may be provided (wholly or partly) as integrated with one or more other components of system 10 (e.g., device 14, the user interface 18, a processor 22, etc.).

[21] the user Interface 18 is configured to provide an interface between system 10 and subject 12 through which the subject 12 may provide information to and receive information from system 10. It allows the sharing of data, results and/or instructions and any other elements of communication, collectively referred to as "information" between the subject 12 and one or more devices from the device 14, electronic storage device 16 and/or processor 22. Examples of interface devices suitable for inclusion in the user interface 18, include a keypad, buttons, switches, a keyboard, knobs, levers, a display device, touch screen, speakers, microphone, indicator light, audible alarm�organization, the printer and/or other interface devices. In one of the embodiments, the user interface 18 includes a plurality of separate interfaces. In one of the embodiments, the user interface 18 includes at least one interface, which is integrated with the device 14.

[22] it Should be understood that the user interface 18 in the present invention also assumed other technologies of data transfer, wired or wireless. For example, in the present invention it is assumed that the user interface 18 may be integrated with a removable storage interface device, provided in the electronic storage device 16. In this example, the information system 10 can be booted from a removable storage device (e.g., smart card, flash drive, removable disk, etc.) that allows the user(s) to customize the implementation of system 10. Other typical input devices and techniques adapted for use in the system 10 as user interface 18 include, but are not limited to, RS-232, RF-link, IR link, modem (telephone, cable or other). In short, any method of sharing information with system 10 is assumed in the present invention in kachestvennaya user 18.

[23] One or more sensors 20 are configured to generate one or more output signals conveying information related to one or more gas parameters of gas inhaled by the subject 12. One or more parameters may include, for example, one or more parameters of flow rate, volume, pressure, composition (e.g. concentration (s) of one or more components), humidity, temperature, acceleration, velocity, acoustics, changes in the parameter, indicating the presence of breath, and/or other gas parameters. In a variant implementation, in which the flow of breathable gas under pressure is delivered to the subject 12 of the device 14, the sensors 20 include sensors that communicate with the gas within the interface of the subject 24.

[24] the Processor 22 is configured to enable the processing of information in the system 10. Thus, the processor 22 may include one or more of a digital processor, an analog processor, a digital circuit designed to process information, an analog circuit designed to process information, a state machine and/or other mechanisms for electronically processing information. Despite the fact that the processor 22 shown in Fig.1 as a single entity, this is done solely for illustrative purposes. In carrying out some�x processor 22 can contain multiple blocks of data. Such blocks of data can physically reside within the same device, or processor 22 may provide the functionality of a group of devices working together.

[25] As shown in Fig.1, the processor 22 may be configured to execute one or more modules of computer programs. One or more modules of computer programs may include one or more of the module parameters of the gas 30, module parameters, respiration 32, comparison module 34, the control module 36, the module target values 38, interface module 40, the mode module 42 and/or other modules. The processor 22 may be configured to execute modules 30, 32, 34, 36, 38, 40 and/or 42 by software; hardware; firmware; some combination of software, hardware and/or firmware; and/or other mechanisms for configuring processing capabilities of the data processor 22.

[26] it Should be understood that although the modules 30, 32, 34, 36, 38, 40 and 42 is illustrated in Fig.1 as placed together in a single processing unit, in implementations in which processor 22 includes multiple processing units, one or more modules 30, 32, 34, 36, 38, 40 and/or 42 can be placed remotely from the other modules. The story, provide a�aamoi modules 30, 32, 34, 36, 38, 40 and/or 42 below for illustrative purposes, and not expected to be limiting, as any of modules 30, 32, 34, 36, 38, 40 and/or 42 may provide more or less functionality than described. For example, one or more modules 30, 32, 34, 36, 38, 40 and/or 42 may be eliminated, and some or all of their functionality may be provided by other modules from among 30, 32, 34, 36, 38, 40 and/or 42. As another example, processor 22 may be configured to perform one or more additional modules that may implement part of the functions or all of the functionality attributed below to one of modules 30, 32, 34, 36, 38, 40 and/or 42.

[27] the Module parameters of the gas 30 is configured to determine information related to one or more gas parameters for the flow of breathable gas under pressure, which is generated by the device 14 and is delivered to the airway of subject 12 via the interface of the subject 24. One or more gas parameters are determined based on output signals of sensors 20. One or more gas parameters may include one or more parameters of pressure, flow rate, magnitude of peak flow, composition, humidity, temperature, acceleration, velocity, diffuse thermal energy (e.g., mass flow meter, etc.), and/or other parameters�ry gas.

[28] the Module parameters of respiration 32 is configured to determine one or more parameters of the breath of the subject 12. The module of respiration parameters 32 may determine one or more breathing parameters based on the one or more gas parameters defined by the module parameters of the strip 30 and/or on the basis of the output signals generated by sensors 20. One or more respiratory parameters comprise one or more parameters of the breathing, conscious change which is requested from the subject 12 through the control signals presented in the flow of breathable gas under pressure. For example, one or more breathing parameters may include one or more parameters of the flow rate of inhalation, duration of inhalation, the flow rate of exhalation, duration of exhalation, tidal volume, respiratory rate, breathing period, peak flow, the shape of the flow curve, the shape of the curve of pressure and/or other breathing parameters.

[29] the comparison Module 34 is configured to compare one or more breathing parameters determined by the module parameters of respiration 32, with a target value of one of more parameters of respiration, control signals, conscious about the change being handed to the subject 12. For example, if the argument of the breath is the tidal volume, then the target parameter is a target about�eat breath. As another example, if the parameter of the breathing is the shape of the curve (e.g., pressure or flow curve of inhalation-exhalation), the target parameter may include a target shape of the curve. Other examples of suitable target parameters (e.g., parameters of respiration, listed above) are obvious.

[30] the control Module 36 is configured to control the device 14. The control device 14 includes a tuning control signal of the breath that is given to the subject 12 to the device 14. As mentioned above, in one embodiment, the control signals of the breath that is delivered to subject 12 to the device 14, includes changing one or more parameters of the flow of breathable gas under pressure delivered from the device 14 to the subject 12. For example, one or more parameters may include pressure, flow rate, and/or the volume flow of breathable gas under pressure. The control module 36 adjusts the control signals of the breath that is given to the subject 12 to the device 14 for the purpose of issuing entity 12 guidance on the conversion of one or more respiratory parameters in accordance with the target values.

[31] for Example, in a variant implementation, in which the device generates a flow of breathable gas under pressure in accordance with the mode BiPAP, moduleprovider 36 may control device 14 to adjust the pressure the flow rate and/or volume of gas delivered to the airway of subject 12 in the process of creating flow under positive pressure of breathable gas at a pressure of HI (e.g., during inhalation). Setting pressure, flow rate and/or volume of gas delivered to the airway of subject 12 in the process of creating a pressurized flow of breathable gas at a pressure of HI will usually manifest itself in the generation of the control signals of breathing, which will give the subject of the 12 indications of the change in the volume of inhaled gas, the change in inspiratory time, a change in the frequency of breath, change of inhaled volume and/or other deliberate changes to one or more breathing parameters.

[32] as another example, in a variant implementation, in which device 14 generates a flow of breathable gas under pressure in accordance with BiPAP mode, the control module 36 may control device 14 to adjust the pressure, flow rate and/or volume of gas delivered to the airway of subject 12 in the process of creating flow under positive pressure of breathable gas at a pressure of LO (e.g., during exhalation). Setting pressure, flow rate and/or volume of gas delivered to the airway of subject 12 in the process of creating flow position under�positive pressure of breathable gas at a pressure of LO usually will manifest in the generation of the control signals of breathing, who will give the subject 12 to the instructions to change the time of expiration, a change in the frequency of breath, change in peak flow of breath, change in exhaled volume and/or other deliberate changes to one or more breathing parameters.

[33] as another example, in a variant implementation, in which device 14 generates a flow of breathable gas under pressure in accordance with BiPAP mode, the control module 36 may control device 14 to adjust the duration of pressure cycles HI and/or LO, the shape of the pressure curve during the transition between cycles of pressure HI and LO, the shape of the flow velocity during the transition between the cycles of HI and LO pressure and/or configure other parameter of the gas flow of breathable gas under pressure. As will be understood, such parameter settings for gas flow of breathable gas under pressure will facilitate the issuance of the subject 12 of the control signals of breathing conscious about the changes one or more parameters of the respiration. For example, such control signals of breathing can give the subject 12 indicating a change in one or more of respiratory rate, time intervals of breathing, the shape of the curve of the flow of breath, the curve of the pressure of breath and/or other breathing parameters.

[34] In one of in�options for implementation, the settings of the flow of breathable gas under pressure produced by the control module 36 using feedback. In this embodiment, the configuration parameters of the flow of breathable gas under pressure may be determined based on the comparison of the breathing parameter and a target threshold value comparison module 34. For example, if the comparison module 34 determines that the parameters of the gas flow of breathable gas under pressure, configured to issue control signals to the breathing of subject 12, are not adequate, the control module 36 will adjust the settings for gas flow of breathable gas under pressure to issue more effective control signals. Control signals of respiration will be determined as inadequate, if the comparison module 34 determines that the control signals of breathing does not allow to issue the subject of 12 indicating a conscious conversion of one or more respiratory parameters in accordance with the target values for one or more parameters of the respiration. This setting can include settings for cases in which the conscious change of one or more parameters of the breathing of subject 12 has not gone far enough (for example, breathing too close to normalisation) and/or for cases in which the conscious change of one or more parameters of the breathing of subject 12 has gone too far.

[35] In one of the embodiments of the configuration parameters of the flow of breathable gas under pressure are performed without feedback. In this embodiment, the implementation of the relationship between one or more gas parameters for the flow of breathable gas under pressure and one or more breathing parameters that must be consciously changed, is determined in advance. Such a predetermined relationship used to generate a flow of breathable gas under pressure with the gas parameters that match the target value for one or more parameters of the respiration. In this embodiment, the implementation of the processor 22 may not include a comparison module 34 and/or sensors 20.

[36] the system target 38 is configured to obtain target values of one or more parameters of the respiration that must be consciously changed. In one embodiment, the implementation of the target values are accepted from the user (for example, from a nurse, subject 12, etc.). The user can enter the target value using the user interface 18. Enter target values may include the introduction of new target values or setting previously obtained target values. Enter target EIT�eny may include configuring the target values in accordance with the predetermined pattern (for example, corresponding to a certain mode of breathing).

[37] In one embodiment, the implementation of the target value determined by the module of the target values of 38 based on the detection of typical levels of one or more parameters of the breathing of subject 12. For example, the target value may be set at a predetermined level above the levels of one or more parameters of the breathing of subject 12. Determining the typical values of one or more breathing parameters of subject 12 may be based on the values defined in the module parameters of respiration 32, the information stored in the electronic storage device 16 for the subject 12, and/or other sources.

[38] the Target value for one or more parameters correspond to the breathing mode of breathing. For example, for the mode of respiration, which includes increased the tidal volume and/or reduced respiratory rate, the target value can include a target level for the inspiratory volume, breathing frequency, and/or other relevant parameters of breathing. As another example, for the mode of breathing associated with the particular shape of the curve of pressure and/or flow rate (e.g., the mode of breathing in yoga, the breath in meditation, the mode of breathing during aerobic and/or anaerobic exercises, Lamaze breathing, etc.), the target value can include a target to form�willow. The target shape of the curve can be processed (e.g., by the user via the user interface 18) indicating the values of the extrema of the target curve (e.g., maxima and/or minima). Within the scope of this presentation can also be implemented in other target values corresponding to data and/or other modes of respiration.

[39] In one embodiment, the implementation module of the target values of 38 sets the initial level of the target value, and then slowly changes the target value over time in the direction of the final target value. Original target values may be based on the basic parameters of the breathing of subject 12 and/or can be set (or adjusted) preliminary. The target value changes over time from an initial target value to a target value can improve the comfort of the control signals of the breath that is given to the subject 12. The target value changes over time may include an increment of the target value, a smooth change in the target value over time and/or other target value changes.

[40] In one of the embodiments, the module target values 38 adjusts the target value on the basis of one or more breathing parameters determined by module parameters, respiration 32. For example, a module with�of anenia 34 may determine the subject 12 does not alter one or more breathing parameters properly in order to bring them into compliance target values. Based on this determination, the module target values 38 may modify the target value so that the alignment was easier, with the control signals of the breath that is given to the subject 12 to the device 14, can be changed by the control module 36 to reflect the changed target value. Module target values 38 may then monitor the compliance of subject 12 new target values (for example, on the basis of comparisons performed by the comparison module 34). If it is determined that the subject 12 corresponds to the new target values, then the module target 38 will change the target value in the direction of the previous target values. If it is determined that the subject 12 is not consistent with the new target values, then the module target 38 can perform another action. For example, the module 36 target values can support target the tidal volume at a constant level as long as the subject 12 will not be consistent, or the module target values 38 may change the target value to reduce the required compliance target value as long as the subject 12 again will not match the values, after which it will resume�been the target value changes in the direction of the final target value.

[41] the Control signals of the breath that is given to the subject 12 through the management of one or more gas parameters for the flow of breathable gas under pressure, can provide an effective means for issuing instructions to the respiratory subject 12 to consciously altering one or more parameters of the respiration. Consciously altering one or more parameters of the respiration in response to control signals of breathing can allow the subject 12 to derive therapeutic benefit during the modified breathing or can afford to study conscious change in one or more breathing parameters during the periods when the subject 12 is not connected to the device 14. For example, the subject 12 can learn the patterns of breathing, appropriate and/or effective for a specific activity (e.g., sport, sports training, yoga, meditation, etc.) that can be run (after training) without the aid of the system 10.

[42] However, in some cases, the subject 12 may initially have difficulty in determining what he needs to do in response to control signals of respiration generated in the flow of breathable gas under pressure. The interface module 40 is configured for dynamic (e.g., configured or updated based on the actual control signals of breathing) renditions� information to subject 12 on the values of reference signals of breathing, issued to the subject of the flow of breathable gas under pressure created by the device 14. In one of the embodiments, interface module 40 controls the user interface 18 for the purpose of transmitting information relating to the control signals of the respiration of the subject 12. Information relating to the control signals of breathing, may include, for example, the instructions at the beginning of exhalation, the end of exhalation and the beginning of the inhalation, the end of breath, accelerated breathing, slow breathing, increase flow, decrease flow, delay of breath and/or other deliberate changes to one or more breathing parameters.

[43] Information related to the control signals of breathing, may be provided to subject 12 by the user interface 18 in the form of audible signals, visual signals, tactile signals, and/or other sensory signals. As a non-limiting example, the user interface 18 may include a radiation source capable of emitting light. The radiation source may contain, for example, one or more of the at least one LED, at least one of an incandescent lamp, a display device and/or other sources. The interface module 40 may control the radiation source so as to emit light in such a way as to pass the subject 12 information�, referring to the control signals of the breath that is given to the subject 12 by a flow of breathable gas under pressure. For example, the radiation source can emit light in the case where control signals of the breath issuing entity 12 indicating the inhalation and may cease to emit light or to emit light of a different color in the case where control signals of the breath issuing entity 12 indicating the exhale. The intensity of the light emitted by the radiation source, may inform the subject of 12 the amplitude of the flow, indicating the creation of which during respiration give the subject 12 control signals of breathing.

[44] Fig.2 and 3 is illustrated an implementation option, in which the interface module 40 controls the set of radiation sources 44 included in the user interface 18, for the purpose of issuing radiation so that it gave information about the control signals of breathing, deliver the flow of breathable gas under pressure. In particular, a set of radiation sources 44 are integrated with the plurality of buttons 46, located on the device 14 to control device 14. In a variant implementation, illustrated in Fig.2 and 3, the radiation source 44 to emit radiation when the control signals of breathing issue 12 subject instructed to breathe, and stop the emission of radiation when the control signals of breathing issue 12 subject instructed to exhale.

[45] let us Return to Fig.1; as another non-limiting example of how the user interface 18 may communicate information about the control signals of respiration of the subject 12, the user interface 18 may include one or more elements capable of generating sounds that can hear the subject 12. The interface module 40 can control the element (s) to generate sounds that report to the subject 12, the value of the control signals being delivered to subject 12 by a flow of breathable gas under pressure. For example, interface module 40 can control the element (s) such that it(they) will be(-ut) to issue a "beep" or a short noise pulse to indicate the subject of 12 of the transition between inhalation and exhalation and/or indicate that the flow should be increased or decreased. The interface module 40 can control the element (s) such that it(they) will be(-ut) to lose the verbal message that will indicate to the subject 12, the value of the control signals of breathing. Verbal messages can be prerecorded and stored on an electronic storage device 16.

[46] as another non-limiting example of how the user interface 18 may communicate information about the control signals of respiration of the subject 12, the user interface�La 18 may include one or more devices, which interact with the subject 12 and provide tactile feedback to the subject 12. For example, the user interface 18 may include a cuff that is worn by the subject 12 is worn around a limb, such as arm, leg, finger, and/or other limbs. In the cuff can be one or more sensors configured to detect a physiological parameter of the subject 12, such as, for example, heart rate, pulse rate, respiratory effort, blood pressure, saturation of blood oxygen and/or other physiological parameters. Cuff can vibrate and/or may pull the limb of the subject 12 with the aim of issuing entity 12 information about the control signals of respiration, such as the transition between inhalation and/or exhalation, or that the flow should be increased or decreased.

[47] as another non-limiting example of how the user interface 18 may communicate information about the control signals of respiration of the subject 12, the user interface 18 may include a display device, which is issued by the subject 12, the text giving the information about the control signals of breathing. The display device may include, for example, the screen on the device 14 and/or other display devices. For example, in Fig.2 and 3 illustrates the user interface 18 includes a display device 48 for the issuance of the subject 12 information about the control signals of breathing, deliver the flow of breathable gas under pressure.

[48] In one of the embodiments, interface module 40 controls the user interface 18 for purposes of obtaining information about the control signals of the breath that is delivered to subject 12 currently and/or on future control signals of breathing. As an example, Fig.4-6 illustrated embodiment of a user interface 18 that includes a display device 48, in which the interface module 40 controls the display device 48 for the purpose of issuing entity 12 information on future control signals of breathing.

[49] returning to Fig.1; mode module 42 is configured to control the modes in which it operates the system 10. Modes in which the system 10 can function, may include modes corresponding to individual modes of breathing. The mode that corresponds to the breathing mode will allow the module target values of 38 to obtain the target values that will lead to the creation of the control signals of breathing, allowing the subject 12 is instructed to breathe in accordance with the mode of breathing. For example, the mode module/install 42 may start the operation of the system 10 in accordance with the modes corresponding to one or more time periods of increased tidal volume and/or low hour�located the whereabouts of breath, the mode of breathing in yoga, the mode of breathing in meditation, mode of respiration in aerobic and/or anaerobic exercise, mode of Lamaze breathing, the breathing mode for use during therapy with pressure support and/or other modes of breathing. Another mode, or multiple modes controlled by the mode module/install 42, may include modes of learning, in which the interface module 40 controls the user interface 18 for the purpose of providing information to subject 12 on the control signals of the breath delivered by a flow of breathable gas under pressure, and the usual modes in which information about the control signals of breathing is not provided to subject 12 via user interface 18.

[50] the mode Module 42 may be configured to allow the subject 12 the ability to manually switch between learning mode and normal mode. This would allow the subject 12 to selectively disable the output of the control signals of respiration of the subject 12 through the user interface 18. Similarly, the mode module 42 may be configured to allow the entity 12 having the option to manually select the mode appropriate to the mode of breathing (e.g., a training mode and/or normal mode corresponding to the mode of breathing). Data entry into a mode module DS selecting the mode of operation of the system 10 may be performed by the subject 12 (or some other user) via the user interface 18.
