[Esophageal pressure and transpulmonary pressure monitoring].
Zhonghua wei zhong bing ji jiu yi xue, 2018Esophageal pressure monitoring provides a minimally invasive method to assess the pleural pressure, which can be used to differentiate the lung and chest wall mechanics. The information of transpulmonary pressure, work of breathing, intrinsic positive end-expiratory pressure and respiratory muscle performance can facilitate the proper setting of ...

Pressure studies in the diagnosis of esophageal disease
The American Journal of Digestive Diseases, 1968Esophageal motility studies, which are simple and harmless to the patient, should form a definite part of the investigative pattern of all lesions of the esophagus. The method to be used has been discussed. Deviations from normal patterns in hiatal hernias, achalasia, vestibular spasms, diffuse spasm, thoracic pain differentiation, postvagotomy ...

Esophageal pressure is used to partition pressure to distend the lung and pressure to distend the chest wall. Esophageal pressure curve in passive patient shows a positive swing during insufflation. The correct position and optimal inflation of esophageal balloon are controlled on the curve.

Measurement of esophageal pressure at bedside
Current Opinion in Critical Care, 2014Esophageal pressure measurement well estimates pleural pressure. The interpretation of absolute values is often debated for various reasons, but the changes in pressure measured are considered very accurate provided that a number of precautions are taken.

Extrapericardial and esophageal pressures with positive end-expiratory pressure in dogs
Journal of Applied Physiology, 1981Using flat balloon techniques to minimize distortion and artifacts, we studied the effect of positive end-expiratory pressure (PEEP) on local surface pressures between the lung and pericardium overlying the right (R) and left (L) ventricles of ventilated closed-chest anesthetized dogs in right lateral decubitus position.

Effect of increased intraabdominal pressure on lower esophageal sphincter pressure
The American Journal of Digestive Diseases, 1975This study evaluates the effect of intraabdominal pressure increases on lower esophageal sphincter (LES) pressure in normal subjects and in patients with reflux esophagitis. Intraabdominal and intragastric pressure were increased by abdominal compression, the Valsalva maneuver, and leg raising.

Correlation of lower esophageal mucosal ring and lower esophageal sphincter pressure
Digestive Diseases and Sciences, 1994We assessed the relationship of lower esophageal sphincter pressure (LESP) to presence and absence of lower esophageal mucosal ring (LEMR) in 66 patients to determine if the LEMR was more likely related to prolonged sphincter hypotension. This potential relationship is of interest because LEMR may be due to reflux esophagitis.

Manometric features of eosinophilic esophagitis in esophageal pressure topography.
Neurogastroenterology and motility, 2011Although most of the patients with eosinophilic esophagitis (EoE) have mucosal and structural changes that could potentially explain their symptoms, it is unclear whether EoE is associated with abnormal esophageal motor function. The aims of this study were to evaluate the esophageal pressure topography (EPT) findings in EoE and to compare them with ...

Abnormal esophageal pressures in reflux esophagitis: cause or effect?
The American journal of gastroenterology, 1986Thirteen patients with gastroesophageal reflux disease underwent esophageal manometric evaluation during acute exacerbations and disease remission to evaluate lower esophageal sphincter and peristaltic pressure in response to treatment. No change was noted in lower esophageal sphincter pressure (15.2 +/- 2.6 mg versus 14.3 +/- 1.8 mm Hg) or peristaltic
