The Rees system in infants: fresh gas flow and PaCO2.
Fresh gas flow from the anaesthetic machine can be set to determine the low level of PaCO2 that is achieved during anaesthesia using Rees variation of the T-piece. It does not however set the upper limits for PaCO2 which is more reliant upon the minute ventilation. For a PaCO2 of 40 mm Hg, it is suggested that the fresh gas flow from the machine be 220 cc/kg. For small infants, a higher flow rate is necessary.
