Pressure support ventilation, sigh adjunct to pressure support ventilation, and neurally adjusted ventilatory assist in infants after cardiac surgery: A physiologic crossover randomized study

Objectives We sought to compare gas exchange, respiratory mechanics, and asynchronies during pressure support ventilation (PSV), sigh adjunct to PSV (PSV SIGH), and neurally adjusted ventilatory assist (NAVA) in hypoxemic infants after cardiac surgery. Design Prospective, single‐center, crossover, randomized physiologic study. Setting Tertiary‐care pediatric intensive care unit. Patients Fourteen hypoxemic infants (median age 11.5 days...
