![]() ![]() increase arterial oxygen tension (PaO2).increased functional residual capacity (FRC) (prevention of airway and alveolar collapse). ![]() increased airway pressure (improves oxygenation and alveolar recruitment).also termed “occult PEEP” by as PEEPi is not apparent on proximal airway pressure recordings (Pepe & Marini, Marino, 2013).less likely to be uniformly distributed than PEEPe.due to insufficient expiratory time (Te), typically in the presence of severe air-flow obstruction (e.g.elevation in the static recoil pressure of the lungs above the set PEEPe at end expiration.a solenoid valve is commonly used in ventilators.a threshold resistor is preferred, as resistance to flow is minimal once threshold pressure is reached.In spontaneous ventilation using non-invasive ventilation (NIV), CPAP (continuous positive airway pressure) is analogous to PEEP, but the pressure applied is maintained throughout the respiratory cycle (during both inspiration and expiration).Įxtrinsic PEEP (PEEPe) is applied by placing resistance in the expiratory limb of a ventilator circuit. ![]()
