SUBSTANCE: invention relates to medicine, namely to resuscitation, and can be applied in case of necessity of carrying out resuscitation actions in case if the patient is in condition of apparent death. For this purpose the injured person is placed in a sitting position. A resuscitator takes position behind and sideways from the injured person, one resuscitators leg rests against the support plane on which the injured person is sitting with its knee. The other leg is half-bent in the knee joint and brought behind the injured person's back, which simultaneously serves as a rest for the injured person and a support for the application of resuscitation. The resuscitator's hand catches the neck, fixing the chin on the elbow bent and throwing back the injured person's head. The other hand fixes the nape, resting with the elbow against the leg, half-bent and brought behind the injured person's back. Resuscitation is realised by bringing the half-bent leg forward, which will lead to straightening of the spine and lowering of the diaphragm - "inhalation". Stopping the influence - return of the resuscitator's leg into the initial position - "exhalation".

EFFECT: method provides effective carrying out resuscitation actions without the application of the breathing assistance with the simultaneous reduction of the time for normalisation of haemodynamical indices and elimination of trauma, aggravating the patient's condition.

Then, the working pressure is reduced depending on patient state starting with a rate of 0.02-0.08 kg/m2/min. Gas exchange and hemodynamic parameters being in norm, the selected rate is increased. The parameters deviating from a norm, the selected rate is adjusted by increasing working pressure to reach their normal values. Optimum gas flow rate is determined and the working pressure is reduced at this rate, continuing to adjust its value under unchanged gas exchange and hemodynamic parameter values or their deviation from norm.

SUBSTANCE: it is necessary to carry out 5-7 courses of complex rehabilitation per 100 trainings/each. Moreover, complex rehabilitation consists of 3 types of trainings. During trainings on social-vocal rehabilitation it is necessary to form fluent and rhythmic speech through deep release of vocal brake and dosed loading upon auditory perception increased from training to training, through pronunciation and psychoemotional sphere. So, at first, it is necessary to activate the brain due to stimulating auditory and vocal areas. During trainings on adaptive-physical rehabilitation it is important to carry out deep muscular pull. The main part of trainings should be supplemented with performing gymnastic exercise known as "piked seat" in static isometric mode. While performing the exercise a patient should achieve the position "legs together, breast - on legs", when the angle formed by a patient's back and legs corresponds to 0. While performing this exercise a patient's back should be additionally affected with external loading as either pressing with a trainer's hands or putting a load onto a patient's back. During trainings on psychological-pedagogical rehabilitation it is necessary to elaborate stress resistance due to multiple repetition of stress loadings being increased from training to training and their psychocorrection. The innovation enables to provide stable effect of recovery at complete absence of disease regress and under condition of excluding medicinal therapy from the course of therapy.

EFFECT: higher efficiency of therapy.
