With or Without ARDS: Evidence Regarding PEEP levels
Journal Title: Journal of Intensive and Critical Care - Year 2017, Vol 3, Issue 2
Abstract
Positive end-expiratory pressure (PEEP) is defined as the alveolar pressure above atmospheric pressure that exists at the end of expiration, and it comprehends the intrinsic PEEP and extrinsic PEEP [1]. Intrinsic PEEP is a dynamic hyperinflation, which may lead to gas trapping, increased end expiration pressure, and hemodynamic instability [1]. It can also be subdivided in static, measured by occluding the airway at end-expiration, and dynamic, measured by recording the change in pressure required to initiate lung inflation [2]. Extrinsic PEEP is an adjustable variable provided by the mechanical ventilator and involves the application of a resistance to expiration in order to produce positive airway pressure, which could stabilize airways, prevent premature airway closure, improve ventilation and reduce gas trapping.
