Conditions

Cardiac Surgical Patients (CABG,Mammary Coronary Bypass Surgery,Plastic and Replacement of Valves, Atrial Septal Defect,Ventricular Septal Defect)

Summary

The goal of this observational study is to evaluate the effectiveness and safety of vibro-acoustic pulmonary therapy (VAPT) in complex therapy for the acute respiratory failure of mixed type I-II stages in comparison with percussion massage in cardiac surgical patients in the early postoperative period.

Interventions

DEVICEVibroacoustic device BARK VibroLUNG

The BARK VibroLUNG vibroacoustic device is intended for the treatment and prevention of respiratory pathologies. The BARK VibroLUNG vibroacoustic device with accessories is a medical device and is intended for the treatment of pathological conditions associated with obstructive and restrictive lung diseases in patients in medical institutions. Field of application: physiotherapy of the chest organs, treatment and prevention of respiratory failure. The therapeutic mechanism of action is due to three main effects: improved bronchial drainage, improved ventilation-perfusion ratios, and the "lung opening" maneuver.
