title: Minimum pulse pressure and peripheral temperature needed for pulse oximetry during cardiac surgery with cardiopulmonary bypass.
abstract: The lowest values of pulse pressure (dPP) and peripheral temperature (Tp) associated with reliable readings from three different pulse oximeters (Biox Ohmeda 3700, Datex Satlite, and Nellcor N-200) were assessed, along with the ability of the pulse oximeters to work immediately before and after total cardiopulmonary bypass (CPB). The lowest mean dPP with a reliable O2 saturation reading was 13 mm Hg and the lowest mean Tp was 23.6 degrees C. The dPP needed for a reliable reading before total CPB did not differ significantly from that needed after total CPB. No significant differences in performance were found among the three oximeters during the study.
