Figure 1.

Vaporizer performance error. Vaporizer performance error (PE) with different fresh gas flows (FGF). PE (%) = 100*(measured output - vaporizer dial)/vaporizer dialed. Thick line = linear regression, with PE = 4.101-1.902*FGF (r2 = 0.23); grey line = non-linear regression (third order polynomial), with PE = 6.990 - 5.959*FGF + 1.099*FGF2 - 0.05192*FGF3.
