Effects of Ventilator Hyperinflation Versus Vibrocompression on Lung Compliance in Mechanically Ventilated Patients

What this Trial Is About

This research aims to compare the effects of two chest physical therapy techniques—ventilator hyperinflation and vibrocompression—on lung compliance in patients who require mechanical ventilation. Mechanical ventilation helps with breathing but can cause problems such as mucus buildup, airway blockage, and lung stiffness, which increase the risk of lung infections and breathing difficulties. The study focuses on how these therapies impact lung function and sputum production in this patient group. Participants will be divided into three groups. One group will receive ventilator hyperinflation plus a traditional chest physical therapy program that includes percussion, postural drainage, and suction. Another group will receive vibrocompression combined with the traditional program. The third group will receive only the traditional chest physical therapy. Each treatment is given once daily over four consecutive days, with ventilator hyperinflation involving controlled increases in breath volume and pressure and vibrocompression involving chest vibrations during exhalation. Patients will be monitored before and after treatments on Days 1 and 4, measuring lung static compliance, airway resistance, sputum volume, and peak inspiratory and expiratory flows. Oxygen saturation will also be assessed as a secondary measure. The study includes detailed evaluations of lung function and secretion clearance to understand how each therapy affects respiratory mechanics and airway clearance. Participation lasts through the four treatment sessions and assessments.
