Middle lobe syndrome

This study compares two ways of setting the breathing machine during gynecologic laparoscopic surgery to prevent lung collapse (atelectasis). One method uses a standard fixed pressure, while the other adjusts the pressure to each patient's lung mechanics. The researchers will use…

This pilot study tests whether keeping the lungs gently ventilated during cardiopulmonary bypass (heart-lung machine) reduces lung collapse after heart surgery. Adults having elective coronary artery bypass surgery will be randomly assigned to receive ventilation or not during by…

This study tests how often doctors should give a brief lung inflation (called a recruitment maneuver) during abdominal laparoscopic surgery to keep the lungs open. Fifty-two older adults having elective surgery will receive these puffs at different intervals, starting every 30 mi…
