摘要
Pharyngeal pressures in 11 preterm infants, receiving binasal Hudson prong continuous positive airway pressure (CPAP)-pressurised by bubbling bottles, were measured. The mean (95% confidence interval) pressure drop from the prongs to the pharynx was 3. 2 (2. 6 to 3. 7) cm H2O with mouths open and 2. 2 (1. 6 to 2. 8) cm H2O with mouths closed. Mouth closure augments CPAP transmission.
