Expiratory pressure prevents alveolar collapse and is delivered by the EPAP (expiratory positive airway pressure) controls on the BiPAP (see Figure 3).
Expiratory positive airway pressure was set at sufficient gas exchange maintenance level and FiO2 was set according to a value of SpO2 of greater than 90%, as measured by pulse oximetry.
There are two pressures that need to be set and adjusted: inspiratory positive airway pressure (IPAP) and expiratory positive airway pressure (EPAP).
