Methods of conserving carbon dioxide in artificially ventilated patients:  a clinical investigation.
A technique is described for maintaining the PaCO2 within, or close to, the normal range in patients hyperventilated using the Mapleson D Circuit or the Circle system with the soda-lime excluded. Control is achieved by limiting the fresh gas inflow to 4-5 litres/minute.
