According to the AARC Clinical Practice Guidelines for application of CPAP to neonates which of the following are true?
I.CPAP maintains inspiratory and expiratory pressure above ambient
II.CPAP improves static lung compliance
III.CPAP can decrease airway resistance
IV CPAP increases mean airway pressure

Question

Quizplus · Accepted Answer

CPAP maintains I)inspiratory and expiratory pressures above ambient pressure,which results in an increase in functional residual capacity (FRC)and II)improvement in static lung compliance,and III)decreased airway resistance in the infant with unstable lung mechanics.This allows a greater volume change per unit of pressure change (i.e.,,greater tidal volume for a given pressure change)with subsequent reduction in the work of breathing and stabilization of minute ventilation (VE).IV)CPAP increases mean airway pressure.
