Intratracheal Pulmonary Ventilation and Continuous Positive Airway Pressure in a Sheep Model of Severe Acute Respiratory Failure

STUDY OBJECTIVES: Previously we have shown that optimal pulmonary gas exchange can be sustained at normal airway pressures in a model of severe acute respiratory failure (ARF), using intratracheal pulmonary ventilation (ITPV), with weaning to room air. In an identical model of ARF, we have now explored whether ITPV, combined with continuous positive airway pressure (CPAP), can sustain adequate ventilation, with weaning to room air. DESIGN: …
