Pulse oximetry during low cardiac output and hypothermia states immediately after open heart surgery. 1989

Department of Anesthesiology, University Central Hospital of Turku, Finland.

Two commercially available pulse oximeters were found to read reliably early during periods of low cardiac index (CI) and low peripheral temperature (Tp). The lowest mean CI and mean Tp values at which a reading could be obtained were 2.4 L/min.m2 and 26.5 degrees C, respectively. The highest mean systemic vascular resistance index was 2930 dyne.sec/cm5.m2. The reliability of one monitor was equally good both in a normal and low perfusion mode (i.e., when the monitor displayed a low-quality signal message). The use of locally applied vasodilating creme widened the physiologic limits within which reliable measurements could be obtained. All oximeters and sensors overestimated slightly the saturation as compared to the hemoximeter readings, possibly because of a high mean carboxyhemoglobin concentration that was found to be present.

D002303	Cardiac Output, Low	A state of subnormal or depressed cardiac output at rest or during stress. It is a characteristic of CARDIOVASCULAR DISEASES, including congenital, valvular, rheumatic, hypertensive, coronary, and cardiomyopathic. The serious form of low cardiac output is characterized by marked reduction in STROKE VOLUME, and systemic vasoconstriction resulting in cold, pale, and sometimes cyanotic extremities.
