Adult HME-filter

Heat and Moisture Exchanger (HME) those in current use are generally combined with a microbiological filter, hence they are called HME filters (HMEF) when passive humidification using an HME is use, the circuit is termed a “dry circuit” as a opposed to a “wet circuit” using active humidification.

Heat and exchange moisturizers (HME) are devices used in mechanically ventilated patients intended to help prevent complications due to "drying of the respiratory mucosa, such as mucus plugging and endotracheal tube (ETT) occlusion."
