DBP, diastolic blood pressure; HR, heart rate; MBP, mean blood pressure; SBP, systolic blood pressure
CO2 data have been published previously.2
Data were transformed for analysis.
Value significantly different from that for isoflurane.
Value significantly different from that for pentobarbital–phenytoin.
