Introduction
CPEP is a therapy which supplies a continuous, clinician-set airway
pressure above atmospheric by use of a venturi, a fixed orifice resistor, and
flow during both inspiration and expiration. CPEP—
• Prevents or reverses atelectasis.
• Delivers hyperinflation therapy through positive expiratory pressure
that will help patients deeply breathe and cough.
• Reduces the incidence of air trapping.
