Pausing after each breath may help COPD patients on ventilators breathe better

This study looked at whether adding a short pause at the end of each breath (called an end-inspiratory pause) helps remove carbon dioxide more efficiently in COPD patients who are on a breathing machine. Fourteen deeply sedated adults with COPD were tested with and without the pause. The goal was to see if this simple change could improve gas exchange without causing lung overinflation. The results could lead to better ventilator settings for COPD patients.
