Edith 1500 Heat-Moisture Exchanger

The Edith 1500 from Vyaire Medical is a heat-moisture exchanger (HME) designed to warm, humidify, and filter the air a patient breathes during mechanical ventilation, anesthesia, or long-term respiratory support. By capturing the heat and moisture from each exhaled breath and returning it on the next inhalation, an HME preserves the natural conditioning normally provided by the upper airway — a function that is bypassed when a patient is intubated or has a tracheostomy.

Clinicians choose the Vyaire Medical Edith 1500 Heat-Moisture Exchanger (557057200) for its balance of humidification performance and low breathing resistance, which matters when maintaining airway moisture without adding significant work of breathing. Keeping secretions thin and mucous membranes moist helps reduce the risk of mucus plugging and airway complications, making passive humidification with an HME a practical alternative to heated humidifier systems in many settings.

Common questions from respiratory therapists and caregivers usually center on when and how to use it. HMEs like the Edith 1500 are single-patient devices intended for continuous use over a defined period, and are typically replaced every 24 hours or sooner if visibly soiled, contaminated with secretions, or if resistance increases. They are best suited to patients with adequate spontaneous tidal volumes and are generally not recommended for those with thick, copious, or bloody secretions, where active heated humidification is preferred.

The Edith 1500 fits naturally alongside other Vyaire respiratory products. If you're managing a tracheostomy patient, pair it with options from our Edith Trach collection, or explore the flexible-connection design of the Edith Flex for circuits that need added maneuverability at the airway.
