Abstract

Computer simulation Cost effectiveness Patient treatment Vapors
A study was carried out to compare the relative induction times and vapor costs associated with two induction strategies: VAPOff and FGFOff. Each induction method was simulated using Gasman for Windows assuming a 70 kg patient. For the first simulation of the intubation period (FGFOff). FGF was turned to 150 ml/min, minute ventilation was set to zero and the vaporizer setting unchanged for one minute. For the second simulation (VAPOff), after the initial three minutes of vapor delivery, the vaporizer was set to zero, minute ventilation was set to zero and the FGF left unchanged for 1 minute. The strategy of turning the FGF to minimum and leaving the vaporizer on during intubation did not contaminate the room and speeds induction by fostering a greater alveolar concentration than the VAOff method. Significant cost savings were obtained using FGFOff.
