The HME-Booster™ makes it possible to feed additional moisture into the system during anesthesia and ventilator care, specifically when the use of an HME alone is no longer adequate due to a patient’s moisture deficit. Only use the Booster T-piece when the Booster heating element is used. The HME-Booster™ can be used with HME's for anesthesia and HME's for ICU, at flow rates between 2L and 12L per minute. The HME-Booster™ has the sole purpose of optimizing the output of the HME. It can only be used at any time in combination with an HME. Not for use with pediatric applications, where tidal volumes are less than or equal to 250 ml and the body weight is less than 20 kg.
