The heat and moisture exchanger (HME), also known as an artificial nose, is a passive humidification device positioned between the patient interface and the breathing circuit. It captures the heat and moisture from the patient's exhaled air and stores it in the exchanger for reuse during inhalation. GGM, as one of the trusted HME suppliers, offers various types of artificial noses, including standard HMEs, tracheostomy-specific HMEs, and HMEs with flexible extension tubes. We also offer a variety of respirator peripheral products, including breathing circuit sets, respiratory humidifiers, and ventilator test lungs.
