Positive 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 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...
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 کاملResponse of Maximum Inspiratory Pressure and Functional Capacity to Positive End-Expiratory Pressure Device after Valvular Heart Surgery
Background: Pulmonary complications following valvular heart surgery are common and contribute to increased duration of hospital stay, rate of morbidity, and mortality. The purpose of the present study was to investigate the response of maximum inspiratory pressure and functional capacity to Positive End-Expiratory Pressure device in patients who underwent valvular hea...
متن کاملPositive End-Expiratory Pressure and Variable Ventilation in Lung-Healthy Rats under General Anesthesia
OBJECTIVES Variable ventilation (VV) seems to improve respiratory function in acute lung injury and may be combined with positive end-expiratory pressure (PEEP) in order to protect the lungs even in healthy subjects. We hypothesized that VV in combination with moderate levels of PEEP reduce the deterioration of pulmonary function related to general anesthesia. Hence, we aimed at evaluating the ...
