WebPEEP was adjusted in small increments and decrements above and below this initial PEEP, and driving pressure was measured at each PEEP level. Subsequently, PEEP was set at the level resulting in the lowest driving pressure, and driving pressure was measured after 1, 5, 15, and 30 min to assess stability over time at constant PEEP. WebOct 18, 2024 · High ventilator driving pressure (measured as plateau pressure – PEEP) is known as a major determinant of lung injury as well as being associated with PCCs. 3 Even though this risk is well known, many patients are still treated with high tidal volume ventilation that includes a wide range of PEEP. WebBackground: In obese patients (OP), the best intraoperative ventilation strategy remains to be defined. Dynamic lung compliance (C dyn) and dead space fraction are indicators of efficient ventilation at an optimal positive end-expiratory pressure (PEEP). dashterqta na poslanika 1 bg sub
