Softer breathing during bypass may speed recovery

This study looked at whether using very small breaths (ultra-low tidal volume) during heart bypass surgery can reduce stress on the lungs and help patients recover faster. Sixty adults having planned bypass surgery were randomly assigned to receive either this gentle breathing method or no breaths at all during the heart-lung machine period. Researchers measured breathing machine power, time on a ventilator, and ICU stay to see if the gentler approach leads to better outcomes.
