Figure 1. Linear plot of halothane MAC versus temperature over the range 28–43 degrees C. The data [2,3,5]are for dogs and are plotted both as gas-phase partial pressures (closed circle;% atm) and as aqueous concentrations (closed square; mM). The latter were calculated [1]using Bunsen saline/gas partition coefficients, obtained for each temperature from a van't Hoff plot of the data in [11]. The straight lines were fitted by the method of unweighted least squares, and the dashed lines represent the 95% confidence envelopes.
