PEEP is of greatest use in ARDS and generated by attaching an airflow threshold resistance device to the expiratory port of the non-rebreathing valve of a manual or mechanical ventilator, allowing a ↓ of airway pressure to a plateau level Conventional PEEP Pressure is maintained at 5-20 cm ...
Expiratory flow limitation was associated with both high and complete “PEEP-absorber” behavior, but setting a relatively high respiratory rate on the ventilator can prevent from observing complete “PEEP-absorption.” Therefore, the effect of PEEP application in patients with auto-PEEP can be accura...
2O at 100 BPM. "inadvertent PEEP" is the result of insufficient expiratory time at high ventilator rates, and its magnitude is decreased by increasing expiratory time.rkA HanRchard uccarMarcJ JarNaturePediatric Research

Nestler and colleagues [11] evaluated the effect of individualized PEEP titrated by electrical impedance imaging (EIT) in obese patients undergoing laparoscopic surgery. They found that compared with normal PEEP group, the iPEEP group reduced atelectasis, decreased ventilator driving pressure, and ...

On the basis of flow and pressure measurements, it is shown that PEEP-valves of the servoventilator offer a considerable flow resistance to the expiration of the patient. The resistance values of the valves are in part above acceptable values. 关键词: Servoventilator PEEP-valve Expiratory resistan...
Patients undergoing general anesthesia and mechanical ventilation during major abdominal surgery commonly develop pulmonary atelectasis and/or hyperinflation of the lungs leading to complications either intraoperatively or in the postoperative period, resulting in ventilator-induced lung injury (VILI) [1, 2]...
of a Lower vs Higher PEEP Strategy on Ventilator-Free Days in ICU Patients Without ARDS JAMA Original Investigation December 22, 2020 This noninferiority trial compares the effects of lower (0-5 cm H2O) vs higher (8 cm H2O) positive end-expiratory pressure (PEEP) on ventilator-free days at...
The increased recruitment group compared with the minimal distension group had a higher median number of ventilator-free days (7 [interquartile range {IQR}, 0-19] vs 3 [IQR, 0-17]; P = .04) and organ failure-free days (6 [IQR, 0-18] vs 2 [IQR, 0-16]; P = .04). This ...
