Lower esophageal sphincter pressure in histologic esophagitis
Digestive Diseases and Sciences, 1980The fasting lower esophageal sphincter pressure of 18 normal volunteers was compared to 22 patients with symptoms and objective evidence of gastroesophageal reflux. Lower esophageal sphincter pressure was measured by rapid pull-through using an 8-lumen radially perfused catheter that sampled pressure every45 degrees around the circumference of the ...

OBJECTIVES Mechanical ventilation is an essential life support technology, but it is associated with side effects in case of over or under-assistance. The monitoring of respiratory effort may facilitate titration of the support.

Esophageal pressure monitoring: why, when and how?
Current Opinion in Critical Care, 2018Purpose of reviewEsophageal manometry has shown its usefulness to estimate transpulmonary pressure, that is lung stress, and the intensity of spontaneous effort in patients with acute respiratory distress syndrome.

Estimating subglottal pressure from esophageal pressure
The Journal of the Acoustical Society of America, 1986A continuing problem in speech research has been the measurement of air pressure in the trachea during the speech act without invading the trachea itself. A common but problematic approach has been to use a pressure measured in the esophagus, at the level of the trachea, via a small balloon at the end of a catheter which leads to an external transducer.

How alterations in pleural pressure influence esophageal pressure
Journal of Applied Physiology, 1984Although esophageal pressures have been substituted for direct pleural pressure measurement in humans, we have investigated the validity of this approach under circumstances when left and right pleural pressures are not equal. Esophageal and bilateral pleural pressures in awake sheep were compared by using matched balloon catheters in close proximity.

Esophageal Pressure Monitoring in ARDS
2013Acute respiratory distress syndrome (ARDS) remains a disease with high mortality rates despite recent therapeutic advances [1]. Although mechanical ventilation can be lifesaving, inappropriate use of the ventilator can itself promote lung injury. It could be useful to know the mechanics characteristics of the respiratory system in order to be able to ...

Esophageal acid sensitivity is believed to develop as a result of esophageal acid exposure, contributing factors being gastroesophageal reflux and delayed esophageal acid clearance. The relationship among lower esophageal sphincter pressure, motor functioning of the body of the esophagus, and esophageal acid sensitivity was examined by comparing the ...

Intraluminal Esophageal Pressures in Speaking Laryngectomees
Annals of Otology, Rhinology & Laryngology, 2010Objectives The objective of the present study was to evaluate intraluminal esophageal pressure during voice and speech emission in speaking laryngectomees with a tracheoesophageal prosthesis. Methods In our prospective analysis in a tertiary-care academic hospital, 25 laryngectomees were divided into 2 groups: 11 speaking individuals with a ...

Esophageal Pressure in Acute Lung Injury
New England Journal of Medicine, 2009observed an improvement in oxygenation in patients with acute lung injury that was man -aged by estimating transpulmonary pressure, there was an extrapulmonary (i.e., abdominal) cause of the acute respiratory distress syndrome (ARDS) in a high proportion of patients in their study (39%).
