hme

HME is an acronym that can refer to several concepts depending on context. Common meanings in healthcare include Heat and Moisture Exchanger and Home Medical Equipment.

Heat and Moisture Exchanger: Known as HME, it is a passive device used in respiratory care to humidify and warm inspired air in patients who are mechanically ventilated or intubated. HMEs conserve heat and humidity from exhaled air and return it to the next inhalation, helping to maintain mucociliary function and reduce airway drying. They are used in anesthesia circuits and intensive care ventilator support. Selection depends on factors such as tidal volume, humidification needs, and the presence of thick secretions. Potential drawbacks include increased airway resistance, risk of mucus plugging if secretions are not managed, and possible carbon dioxide retention in high minute ventilation. HMEs require regular monitoring and timely replacement to prevent infection or obstruction.

Home Medical Equipment: HME also denotes Home Medical Equipment, the durable medical equipment supplied for use at home under professional prescription. This includes oxygen therapy devices, CPAP/BiPAP machines, wheelchair equipment, hospital beds, bathroom safety aids, inhalation devices, suction equipment, and more. Suppliers organize rental or sale, delivery, setup, maintenance, and user training. Insurance coverage, including Medicare in some jurisdictions, often supports DME when prescribed for a diagnosed condition and when appropriate for home use. Regulation emphasizes durability, medical purpose, and suitability for home use.
