BACKGROUND Combined effects of leaks, mechanical property of respiratory system and upper airway (UA) patency on patient-ventilator synchrony (PVA) and the level of clinically "tolerable" leaks are not well established in home ventilators. METHODS We comparatively assessed on a bench model, the highest leak level tolerated without inducing significant asynchrony ("critical leak") in three hom...

BACKGROUND The standard of care of patients with cancer of cardia and esophagus still remains surgery in early stage. One of the most feared complications after such procedure is anastomotic leak. AIM We present our experience with omental wrapping of anastomosis (omentoplasty) to decrease the anastomotic leak. SETTINGS AND DESIGN Retrospective study. MATERIALS AND METHODS An analysis of ...

Altered sarcoplasmic reticulum (SR) Ca2+-ATPase and Na+-Ca2+ exchange (NCX) function have been implicated in depressing SR Ca2+ content and contractile function in heart failure (HF). Enhanced diastolic ryanodine receptor (RyR) leak could also lower SR Ca2+ load in HF, but direct cellular measurements are lacking. In this study, we measure SR Ca2+ leak directly in intact isolated rabbit ventric...

Water utilities are challenged to reduce their water losses through detecting, localizing, and repairing leaks as quickly possible in aging distribution systems. In this work, we solve challenging problem by detecting multiple simultaneously a network for the Battle of Leak Detection Isolation Methods. The performance leak detection localization depends on how well system roughness demand calib...

In order to solve the selection of the optimal wavelet basis for the gas pipeline leak monitoring, the feature of wavelet basis especially for gas pipeline leak monitoring and positioning has been summarized based on the analyze of wavelet basis parameters characteristic and gas pipeline leak negative pressure wave signal feature. A parameter which named reconstruction and mutation joint factor...

Laparoscopic sleeve gastrectomy is used increasingly for obesity treatment. The most important complications of this procedure are bleeding and staple line leak. In this article, a 44-year-old female patient who developed a leak at the gastro-oesophageal junction following a revision laparoscopic sleeve gastrectomy is presented. The leak was recognized by computerized tomography and fluoroscopy...

Recently, the vacuum technology has gained a significant relevance in many areas of basic research and applied science. Low-pressure environment of various quality is in common use in the top technology industrial applications. In the most cases, the leaks are the most common sources of deterioration in quality of vacuum. Therefore, the leak detection and consequential leak localization become ...

The incidence of pulmonary air leak in 230 infants with a birth weight of 500-999 g who were ventilated was 41%. Pulmonary interstitial emphysema occurred in 35%, pneumothorax in 20%, pneumomediastinum in 3%, and pneumopericardium in 2%. The survival rates in those with or without pulmonary air leak were not significantly different in the first four years of the study period (46% v 53%). As the...

The development of a persistent air-leak due to secondary pneumothorax in patients with COPD is a difficult problem. Treatment options can include surgery, pleurodesis, and various endoscopic techniques. The use of one-way valves has been reported in patients with broncho-pleural and alveolo-pleural fistulae arising after surgical resection as well as after secondary pneumothorax. Isolating the...

OBJECTIVE To investigate the compressive force applied to the head during mask ventilation and determine whether this force increases in response to an attempt to correct the mask leak. METHODS The authors asked 24 participants (consultants, fellows and nurses) to administer positive pressure ventilation to a modified leak-free, term newborn manikin using a self-inflating bag (SIB) and a Neop...
