Abstract
We report the bench testing of three new anaesthesia ventilators : Fle xima(TM) (Datex), SA2/RA2(TM) and Cato(TM) (Drager). The test circuit included a two compartment lung model, a pneumotachograph and a pressu re gauge. Volume was integrated from flow signal. The tidal volume del ivered by the Flexima(TM) and SA2/RA2(TM) ventilators decreased with i ncreasing mechanical work load contrarily to the Cato(TM). Moreover, t he tidal volume of the Flexima(TM) increased with the fresh gas flow. In spontaneous ventilation inspiratory resistance were low.
