In vitro evaluation of heat and moisture exchangers designed for spontaneously breathing tracheostomized patients.
BACKGROUND Heat and moisture exchangers (HMEs) are commonly used in chronically tracheostomized spontaneously breathing patients, to condition inhaled air, maintain lower airway function, and minimize the viscosity of secretions. Supplemental oxygen (O2) can be added to most HMEs designed for spontaneously breathing tracheostomized patients. We tested the efficiency of 7 HMEs designed for spont...
متن کاملInfluence of breathing resistance of heat and moisture exchangers on tracheal climate and breathing pattern in laryngectomized individuals.
BACKGROUND The aim of this study was to determine the influence of breathing resistance of heat and moisture exchangers (HMEs) on endotracheal climate and breathing pattern. METHODS Endotracheal temperature and humidity and tidal volumes were measured in 11 laryngectomized patients with a regularly used HME with "standard" breathing resistance (Provox Normal HME; R-HME), a low breathing-resis...
متن کاملEfficiency of airway heat and moisture exchangers in anesthetized humans.
The efficiencies of airway heat and moisture exchanging filters in reducing respiratory water losses and increasing airway temperatures during general anesthesia were studied in five tracheally intubated patients given isoflurane, nitrous oxide, and oxygen anesthesia during controlled ventilation. Filters (Humid-Vent Filter, Humid-Vent 1, Pall Conserve, Siemens 150, and ThermoVent 600) were pla...
متن کاملHeat-moisture exchangers and risk of nosocomial pneumonia.
ICU, 14% [before patient contact] and 25% [after patient con-tact]; cardiac surgery ICU, 6% [before] and 13% [after]). Observations in the medical ICU after introduction of the new, increasingly accessible, alcohol-based, waterless hand antiseptic revealed significantly higher handwashing rates (F<.05). Handwashing compliance improved as accessibility was enhanced: before patient contact, 19%, ...
متن کاملHumidification Performance of Heat and Moisture Exchangers for Pediatric Use
Background. While heat and moisture exchangers (HMEs) have been increasingly used for humidification during mechanical ventilation, the efficacy of pediatric HMEs has not yet been fully evaluated. Methods. We tested ten pediatric HMEs when mechanically ventilating a model lung at respiratory rates of 20 and 30 breaths/min and pressure control of 10, 15, and 20 cmH(2)O. The expiratory gas passed...
