Table 1 Carbon monoxide concentrations. Legend: Peak and median interquartile range carbon monoxide concentration [CO] in parts per million for each experiment: ex.1 = experiment 1, ex.2= experiment 2, both with desflurane 3.0 vol%, enflurane 0.6 vol%, isoflurane 0.6 vol%, halothane 0.45 vol% and sevoflurane 0.8 vol% in completely dry sodalime.

From: Carbon monoxide production from five volatile anesthetics in dry sodalime in a patient model: halothane and sevoflurane do produce carbon monoxide; temperature is a poor predictor of carbon monoxide production
