Heat and moisture exchanger filter (breathing circuit)
A single-use device placed in the breathing circuit next to the patient, combining a bidirectional antimicrobial filter with recovery of heat and moisture from exhaled air.
How it is used
Conditioning of inspired gas and reduction of circuit cross-contamination during general anesthesia.
Clinical tip
It is recommended not to rely solely on electrostatic HMEFs, combining them with a second mechanical filter on the expiratory limb for better viral filtration.
