The patient signs an informed consent to participate in the study after 10-12 hours tracheal extubation and transfer of the patient to spontaneous respiration. The application of one or another method of influence is carried out by the method of random sampling (the envelope method). Next, a session is conducted using one of the methods of vibrational respiratory therapy. We are exploring the gas composition of arterial blood is examined, spirometry, and the respiratory rate is measured after 20 minutes of the procedure. Further, respiratory therapy sessions are repeated 3 times a day for three days
There will be formed of groups for application of vibration methods on the lungs: the method of vibroacoustic lung massage using the BARK VibroLUNG device; the method of oscillating PEP therapy using Acapella DH Green; the method of hardware stimulation of cough with a mechanical insufflator-aspirator Comfort Cough Plus (Comfortable cough Plus). As a control group, classical manual chest massage with percussion and verbal stimulation of cough against the background of chest compressions with a total duration of 15 minutes will be used
