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 ...
Specifically, clinicians may not readily detect or recognize the presence of Auto-PEEP during volume ventilation of a triggering patient exhibiting an obstructive component. According to embodiments, a ventilator may be configured to monitor and evaluate diverse ventilatory parameters to detect Auto-PEEP ...
Baseline ventilator settings were at a rate of 50/min, inspiratory:expiratory (I:E) ratio of 2:1 or 4:1, and minute ventilation was manipulated to create 3 or 5 cm H2O PEEPi-stat. PEEPi-stat was measured using the expiratory hold button of the ventilator. PEEPi-dyn showed large ...
At the start of an experiment, the umbilical cord was clamped and the animal was ventilated with a F r o , of 1.0 using a Harvard animal ventilator in a closed system with an O,-filled spirometer and calcium carbonate for CO, absorption. After an initial equilibration period, the animal ...

How to optimise PEEP is a controversial topic, but should involve (1) optimisation of oxygenation and (2) minimisation of ventilator induced lung injury (VILI), and should should be individualised for a given patient “High” PEEP is used as part of an Open Lung Approach To Ventilation for ...
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...
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...
