A patient has been using continuous positive airway pressure (CPAP), and now the health care provider is recommending bi-level positive airway pressure (BiPAP). The patient is asking the nurse to explain the difference again
Which response is appropriate?
a. "CPAP maintains a set positive airway pressure during inspiration only."
b. "CPAP opens the airways during inspiration and allows them to close during expiration."
c. "BiPAP maintains a set pressure that is the same for inspiration and expiration."
d. "BiPAP delivers sufficient expiratory pressure to keep the airways open."
D
BiPAP uses two modes of pressure: one for inspiration and one for expiration. During expiration, BiPAP delivers sufficient pressure to keep the airways open. CPAP maintains a set positive airway pressure during inspiration and expiration. It keeps the airways open and prevents upper airway collapse.
