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 کاملClinical review: Positive end-expiratory pressure and cardiac output
In patients with acute lung injury, high levels of positive end-expiratory pressure (PEEP) may be necessary to maintain or restore oxygenation, despite the fact that 'aggressive' mechanical ventilation can markedly affect cardiac function in a complex and often unpredictable fashion. As heart rate usually does not change with PEEP, the entire fall in cardiac output is a consequence of a reducti...
متن کاملInteraction between Positive End Expiratory Pressure and Cardiac Index
Positive end-expiratory pressure (PEEP) is essential in the management of acute respiratory failure (ARF) and acute respiratory distress syndrome (ARDS) in children and adults. Several studies have addressed the pulmonary beneficial effect and cardiovascular impact of an elevated PEEP in adults. However, the impact of an elevated PEEP on the respiratory and cardiovascular systems has not been w...
متن کاملAirway mechanosensor behavior during application of positive end-expiratory pressure.
BACKGROUND Positive end-expiratory pressure (PEEP) is commonly used in clinical settings. It is expected to affect the input from slowly adapting pulmonary stretch receptors (SARs), leading to altered cardiopulmonary functions. However, we know little about how SARs behave during PEEP application. OBJECTIVES Our study aimed to characterize the behavior of SARs during PEEP application. METHO...
متن کاملApplication of positive end expiratory pressure during laparoscopic surgery
provided the original work is properly cited. CC Positive-pressure ventilation during general anesthesia is a prerequisite for numerous surgical conditions. Mechanical ventilation is non-physiological and can induce lung injury, although ventilator-induced lung injury may be of minor clinical importance during anesthesia for most patients with healthy lungs. However, growing evidence suggests t...
