Please refer to the Instructions for Use of the pulmonary artery catheter to determine the [Comp. Const] and

15.5 Measuring the Blood Temperature
As shown below, the blood temperature is measured with a temperature sensor at the distal end of the catheter in the
pulmonary artery. During C.O. measurements, blood temperature alarms are suppressed to avoid false alarms. They will
automatically recover as soon as the C.O. measurements are completed.
