WebOct 10, 2024 · When increasing PEEP does not recruit functional lung units and improve pulmonary compliance, it will increase lung distention and energy transfer to the pulmonary-parenchymal matrix [ 8 ]. This raises the risk of lung injury, dead-space formation, pneumothorax, and detrimental hemodynamic consequences. WebSep 17, 2016 · PEEP can cause hemodynamic instability secondary to decreased venous return, just like high levels of PEEP. 7 PEEP may be detected in two ways: (1) evaluation of the flow-time trace or (2) disconnection of the patient from the ventilator and listening for additional exhaled gas after an exhalation should have occurred. 6 The flow-time trace … bowker customer loginWebPEEP indicates positive end-expiratory pressure. aPatients could have more than 1 reason for exclusion; the main reason for exclusion is presented. bIncludes chronic obstructive pulmonary disease (COPD) stages III and IV in the Global Initiative for COPD (GOLD) classification and restrictive pulmonary disease. gulf war archives
