Effect of peep on esophageal catheter optimal calibration volume and esophageal pressure measurements
Introduction The use of esophageal balloon catheter to estimate pleural pressure has gained renewed popularity in recent years. Indeed, measurement of transpulmonary pressure may allow a more pathophysiological-based approach to ventilator strategy in ARDS patients. Nevertheless it is well known that esophageal balloon catheter derived parameters can be influenced by several patient-related or ...
متن کاملEsophageal and gastric pressure measurements.
The measurement of esophageal and gastric pressures with balloon-tipped catheters has been used with great success over the past half century to delineate the physiology of the mechanical respiratory system. Pleural pressure and abdominal pressure values estimated from esophageal and gastric pressure measurements allow analysis of lung and chest wall compliance, as well as work of breathing, re...
متن کاملPEEP guided by esophageal pressure--any added value?
Treatment of the acute respiratory distress syndrome (ARDS) with positive end-expiratory pressure (PEEP) was introduced more than 40 years ago.1,2 Few practitioners question the effects of PEEP on hemoglobin saturation, but the optimal dose titration is controversial. Usually PEEP is simply adjusted to a suitable increase in oxygenation efficiency (i.e., the ratio of the partial pressure of art...
متن کاملIn vivo calibration of esophageal pressure in the mechanically ventilated patient makes measurements reliable
BACKGROUND Esophageal pressure (Pes) can provide information to guide mechanical ventilation in acute respiratory failure. However, both relative changes and absolute values of Pes can be affected by inappropriate filling of the esophageal balloon and by the elastance of the esophagus wall. We evaluated the feasibility and effectiveness of a calibration procedure consisting in optimization of b...
متن کاملEffect of ginger on lower esophageal sphincter pressure.
OBJECTIVE Ginger has been traditionally used to reduce intestinal gas and flatulence. The present study examined the effects of ginger on the esophagus and lower esophageal sphincter (LES) function by esophageal manometry. STUDY DESIGN A randomized controlled trial. SETTING Departments of Physiology and Medicine, Faculty of Medicine Siriraj Hospital. SUBJECTS Fourteen healthy young male v...
