Which of the following statements concerning the use of the Fisher & Paykel Healthcare Bubble CPAP System is true?

a. The bubbling in the continuous positive airway pressure generator should be vig-orous.
b. Blanching around the nostril rim suggests that the prongs are too long.
c. If the prongs are too small, there is a de-crease in airway pressure.
d. Place the prongs, with the curved side up, into the infant's nares.

ANS: B
Large prongs decrease blood flow to the area, causing blanching of the rim of the nostrils. The bubbling in the continuous positive airway pressure generator should be gentle and continuous. If the prongs are too small, there will be an increase in airway pressure, and gas will leak from the system. The prongs should be placed, with the curved side down, into the infant's nostrils.
