IMPROVED OXYGENATION DURING STANDING PERFORMANCE OF DEEP BREATHING EXERCISES WITH POSITIVE EXPIRATORY PRESSURE AFTER CARDIAC SURGERY: A RANDOMIZED CONTROLLED TRIAL

摘要

Objective: Breathing exercises after cardiac surgery are often performed in a sitting position. It is unknown whether oxygenation would be better in the standing position. The aim of this study was to evaluate oxygenation and subjecfive breathing ability during sitting vs standing performance of deep breathing exercises on the second day after cardiac surgery.
