14 de oct. de 2022 · Positive end-expiratory pressure (PEEP) is used therapeutically during mechanical ventilation (extrinsic PEEP). It can also be a complication of incomplete expiration and airtrapping (intrinsic PEEP). Clinical aspects of extrinsic and intrinsic and PEEP are discussed in this topic review.
14 de ago. de 2023 · Other adverse effects of extrinsic PEEP include its capacity for generating barotrauma, especially in non-compliant lungs by increasing plateau pressures, and its interference with hemodynamic measurements in patients with right-heart catheters.
5 de dic. de 2017 · PEEP can also negatively impact systemic circulation through its effects on right ventricle loading conditions , and afterload (19,20). Indeed, one recent trial of PEEP in surgery patients showed much more episodes of shock during the surgical procedure with the use of higher levels of PEEP .
The hemodynamic consequences of PEEP are often overtly apparent at the bedside, whereas its adverse effects on the lung parenchyma may be more insidious. PEEP may also contribute to VILI by increasing lung stress and strain.
18 de oct. de 2005 · Whatever the major component of PEEP-induced reduction in LV afterload may be, that decrease in afterload usually does not translate into increased cardiac output, as the adverse effects on LV filling usually predominate. The failing heart, however, is more sensitive to decreased afterload.
15 de jul. de 2021 · The use of higher PEEP, compared to lower PEEP, is associated with reduced mortality among patients with moderate-severe ARDS [ 8 ], who better respond to the application of PEEP in terms of increased size of ventilated lung [ 9 ], reduced atelectrauma [ 10 ], and improved oxygenation [ 11] than patients with mild ARDS.
