Abstract
Water humidity and temperature were measured in the proximal end of the inspiratory limb in anaesthetic circuits used to anaesthetize three groups of adult patients using various fresh gas flows (FGF). Humidity increased as FGF's were lowered, with 98% water humidification achieved when FGF's of less than 0.5 1/min were administered. Temperature at the same site changed about 1–2.5d̀C in inverse proportion to the volume of FGF. This advantage of closed system and low flow anaesthesia is a further reason for their wide-spread utilization.This publication has 19 references indexed in Scilit:
