The quest for optimal positive end-expiratory pressure continues
With interest we have read the paper by Carvalho and colleagues, in which the authors report the results of their elegant study on the role of positive end-expiratory pressure (PEEP) in acute lung injury [1]. Carvalho and colleagues demonstrated in an acute respiratory distress syndrome (ARDS) model that alveolar hyperinflation and nonaerated areas may coincide during a stepwise reduction of PE...
متن کاملPositive end-expiratory pressure.
PURPOSE OF REVIEW In the last 2 years, several reports have dealt with recruitment/positive end-expiratory pressure (PEEP) selection. Most of them confirm previous results and few add new information. RECENT FINDINGS It has been definitely confirmed that opening pressures are different throughout the acute respiratory distress syndrome lung parenchyma, ranging from 5-10 up to 30-40 cmH2O. The...
متن کاملThe optimal time for measuring the cardiorespiratory effects of positive end-expiratory pressure.
No study has elucidated the minimum time taken for oxygen delivery to reach steady-state levels after an increase in positive end-expiratory pressure (PEEP). We therefore investigated ten ventilated patients who received a total of 27 increments in PEEP of 5 cm H2O. Cardiorespiratory parameters were measured at baseline, at 1 min, and thereafter at 5-min intervals until 2 consecutive measuremen...
متن کاملPositive end-expiratory pressure or no positive end-expiratory pressure: is that the question to be asked?
Positive end-expiratory pressure (PEEP) is an essential technique for the respiratory care of many critically ill patients who require ventilatory support. With the application of PEEP, the baseline end-expiratory pressure in mechanically ventilated patients is elevated above atmospheric pressure. In general, the application of PEEP is expected to improve lung mechanics and gas exchange as it r...
متن کاملInteraction Between Intra-Abdominal Pressure and Positive-End Expiratory Pressure
OBJECTIVE The aim of this study was to quantify the interaction between increased intra-abdominal pressure and Positive-End Expiratory Pressure. METHODS In 30 mechanically ventilated ICU patients with a fixed tidal volume, respiratory system plateau and abdominal pressure were measured at a Positive-End Expiratory Pressure level of zero and 10 cm H2O. The measurements were repeated after plac...
