An assessment of the Humphrey ADE anaesthetic system in the Mapleson A mode during spontaneous ventilation.
The Humphrey ADE anaesthetic breathing system in the Mapleson A mode has been compared with the Magill system in spontaneously breathing conscious volunteers and anaesthetised patients. In the latter, rebreathing occurred at a significantly lower fresh gas flow with the ADE system than when the Magill system was used (mean 45.6 ml/kg/minute and 56.5 ml/kg/minute respectively). There was no significant difference between the fresh gas flow at which rebreathing occurred in conscious volunteers.
