ĬPAP may be used in the neonatal intensive care unit (NICU) to treat preterm infants whose lungs have not yet fully developed and who may have respiratory distress syndrome from surfactant deficiency. OSA may arise from a variety of causes such as obesity, hypotonia, adenotonsillar hypertrophy, among others. Airway collapse is typically seen in adults and children who have breathing problems such as obstructive sleep apnea (OSA), which is a cessation or pause in breathing while asleep. It can also indirectly aid in ventilation, although CPAP alone is often inadequate for supporting ventilation, which requires additional pressure support during inspiration (IPAP on BiPAP) for non-invasive ventilation.Īirway collapse can occur from various causes, and CPAP is used to maintain airway patency in many of these instances. The application of CPAP maintains PEEP, can decrease atelectasis, increases the surface area of the alveolus, improves V/Q matching, and hence, improves oxygenation. In CPAP no additional pressure above the set level is provided, and patients are required to initiate all of their breaths. These pressures are known as inspiratory positive airway pressure (IPAP) and expiratory positive airway pressure (EPAP). CPAP differs from bilevel positive airway pressure (BiPAP) where the pressure delivered differs based on whether the patient is inhaling or exhaling. It is measured in centimeters of water pressure (cm H2O). CPAP is a way of delivering PEEP but also maintains the set pressure throughout the respiratory cycle, during both inspiration and expiration. Positive end-expiratory pressure (PEEP) is the pressure in the alveoli above atmospheric pressure at the end of expiration. Continuous positive airway pressure (CPAP) is a type of positive airway pressure, where the air flow is introduced into the airways to maintain a continuous pressure to constantly stent the airways open, in people who are breathing spontaneously.
