Matching positive end-expiratory pressure to intra-abdominal pressure improves oxygenation in a porcine sick lung model of intra-abdominal hypertension
INTRODUCTION Intra-abdominal hypertension (IAH) causes atelectasis, reduces lung volumes and increases respiratory system elastance. Positive end-expiratory pressure (PEEP) in the setting of IAH and healthy lungs improves lung volumes but not oxygenation. However, critically ill patients with IAH often suffer from acute lung injury (ALI). This study, therefore, examined the respiratory and card...
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 کاملIntra-abdominal pressure, intra-abdominal hypertension, and pregnancy: a review
The last several decades have seen many advances in the recognition and prevention of the abdominal compartment syndrome (ACS) and its precursor, intra-abdominal hypertension (IAH). There has also been a relative explosion of knowledge in the critical care, trauma, and surgical populations, and the inception of a society dedicated to its understanding, the World Society of the Abdominal Compart...
متن کاملIntegration of inspiratory and expiratory intra-abdominal pressure: a novel concept looking at mean intra-abdominal pressure
BACKGROUND The intra-abdominal pressure (IAP) is an important clinical parameter that can significantly change during respiration. Currently, IAP is recorded at end-expiration (IAPee), while continuous IAP changes during respiration (ΔIAP) are ignored. Herein, a novel concept of considering continuous IAP changes during respiration is presented. METHODS Based on the geometric mean of the IAP ...
متن کاملCompartment pressure of the rectus sheath accurately reflects intra-abdominal pressure in a porcine model.
BACKGROUND To investigate whether the compartment pressure of the rectus sheath (CPRS) reflects the intra-abdominal pressure (IAP) under various conditions of intra-abdominal hypertension (IAH) in a pig model. METHODS DESIGN Prospective experimental study with in vivo pressure measurements. SETTING Institute for Clinical and Experimental Surgery, University of Saarland. ANIMALS Seven d...
