Heat Moisture Exchange and HME Filters

Humidification during mechanical ventilation is necessary to prevent inspissation of airway secretions, hypothermia, and atelectasis. This can be accomplished using either a heat moisture exchange filter (HME) or a heated humidifier. A humidification device should provide a minimum of 30 mg H2O/L of delivered gas at 33+/- 2 degrees C during the exchange. HME filters are passive humidification systems that retain heat and moisture from the patient's exhaled gas via a hygroscopic filter.

MEDICOMP media has a condensation surface with hygroscopic coating. this helps ensure the HME filters provide effective moisture exchange and heat retention thus minimizing the moisture and heat loss of the patient. MEDICOMP HME filters help create normal conditions in the patient's airway and lungs during exchange, which helps to reduce the risk of breathing and lung complications for patients in critical care and anesthesia environments.

MEDICOMP offers several different combined heat moisture exchange and heat moisture exchange filters filters. All HME filters are designed for applications in Critical Care, Respiratory Care, and Anesthesia. All heat moisture exchange filter combinations provide excellent moisture output greater than 30 mg H2O/L and also help provide efficient protection for both the patient and the equipment against various types of particles present in the breathing circuit. All HME and heat moisture efficiency filters are designed according to ISO standards to help facilitate connection to different ventilators and anesthesia systems.
