15-Second breath test may guide fluid therapy in sick infants

This study tested whether a 15-second pause in breathing (end-expiratory occlusion) can predict if giving fluids will improve blood flow in infants under 2 years old who are in shock and on a breathing machine. Ten infants in intensive care were monitored with ultrasound before and after the pause and after receiving fluids. The goal was to see if changes in heart output during the pause could identify which infants would benefit from more fluids.
