Comparing Two Positive Pressure Therapies to Prevent Lung Problems After Heart Surgery A Study of CPAP Versus PSPEEP in Postoperative Cardiac Patients

What this Trial Is About

Researchers are evaluating two types of positive pressure therapies, continuous positive airway pressure CPAP and positive pressure support with positive end-expiratory pressure PSPEEP, to reduce lung complications after heart surgeries such as myocardial revascularization and valve replacement or plastic surgery. These lung complications are common after cardiac surgery and can increase hospital stays and risks to health. The study aims to find out if PSPEEP and CPAP have similar effects in improving lung function in patients with mild to moderate lung problems immediately after surgery. Participants will be randomly assigned to one of two groups during the immediate postoperative period. One group will receive PSPEEP therapy involving four sets of 20 breaths with pressure settings tailored to body weight and oxygen levels. The other group will receive CPAP therapy set at a constant pressure for 30 minutes to maintain oxygen saturation. Both therapies aim to support lung expansion and oxygen levels to help recovery. During the study, participants will undergo lung function tests including spirometry, respiratory muscle strength, handgrip strength, and electrical impedance tomography to monitor lung ventilation during and after therapy. Researchers will follow participants for seven days after surgery to assess lung complications. Additional assessments include length of ICU and hospital stay, comfort with therapy, and muscle strength on days 5 and 7 post-surgery. This comprehensive monitoring helps evaluate how the therapies affect recovery and lung health over time.
