Physiologic comparison of neurally adjusted ventilator assist, proportional assist and pressure support ventilation in critically ill patients To compare, in a group of difficult to wean critically ill patients, the short-term effects of neurally adjusted ventilator assist (NAVA), proportional ass... ...
INTERVENTIONS: Patients were randomized to undergo either CPAP (with PEEP 10[Symbol: see text]cmH(2)O) or PAV (with PEEP 5-6[Symbol: see text]cmH(2)O) noninvasive ventilation through a full face mask and the same ventilator. MEASUREMENTS AND RESULTS: The main outcome measure was the ...
Common methods include the T-piece, which involves an immediate shift from full ventilator support to a period of breathing without ventilator assistance, and a program of pressure support ventilation (PSV), which gradually reduces the amount of ventilator support. Delayed weaning may lead to ...
The initial ACV ventilator settings as defined during the first 3 h after enrolment before application of the randomised strategy (ACV with a tidal volume of 6 mL/kg PBW and PEEP to reach an inspiratory plateau pressure of 28 cmH2O, as in the PC-SV group) were maintained during the first...
以前我们说是不是PEEP很重要,但是他们通过一些data告诉我们,驱动压才是中间最重要的关键环节。 CONCLUSIONS We found that△P was the ventilation variable that best stratified risk. Decreases in△P owing to changes in ventilator settings w...
Recent interest in newer ventilatory support modes has been stimulated by the fact that the only thing we can offer the patient with severe acute respiratory failure (ARF) is to buy time and allow the lung to heal by itself. The mortality from acute adult respiratory distress syndrome (ARDS)...

However, assuming the mortalities attributable to ventilator-induced lung injury is 10% would indicate that all deaths due to ventilator-induced lung injury "would need to be avoided by using the esophageal pressure-guided PEEP titration compared with the empirical high PEEP-FIO2 table," they noted...
H2O with alveolar recruitment maneuvers performed after endotracheal intubation, which were repeated every hour after any disconnection from the mechanical ventilator and before the end of surgery (high level of PEEP group) or (2) a PEEP level of 4 cm H2O (low level of PEEP group) (Figure 1...
