Heated Humidifiers
Heated humidifiers or heated breathing circuits are typically a sealed heated wire within one limb of the breathing circuit. Sterile water is introduced into the circuit and the servomechanism controlled heater maintains temperature. These devices are prone to hazards, such as overheating, condensation, changes in the compressible volume of the circuit, leaks in the tubing, and obstruction, if they are not connected correctly. They are superior to any other device for preventing the secretions in the airway from drying out and are universally used with ICU ventilators. However, as the circle breathing circuit supplanted the Mapleson F circuit (Jackson-Rees modification of the Ayre T-piece) in clinical anesthesia care globally, heated humidifiers became anachronistic as it could be difficult to adapt them to the circle circuit. The additional cost and complications of these devices also limit their use except for anesthesia cases of prolonged duration. Manufacturers include


Heated humidifiers operate actively to increase the heat and water vapor content of inspired gas. HMEs operate passively by storing heat and moisture from the patient's exhaled gas and releasing it to the inhaled gas.
