Minimum arterial pressures in the mouse over two 23-h periods. Mice were housed at a Ta of 19°C for 1 day while fed (euthermic, open bars). The following day, the mice were fasted and all entered bouts of torpor (torpid, solid bars). Minimum pulse pressure was not significantly different between the two states, whereas minimum systolic, mean, and diastolic arterial pressures were all significantly lower in the torpid state than the minimum pressures in the euthermic state. *P < 0.05 in euthermic vs. torpid.
