Cooximeter | definition of cooximeter by Medical dictionary
oximeter (redirected from cooximeter)
Also found in: Dictionary
a photoelectric device that measures oxygen saturation of the blood by recording the amount of light transmitted or reflected by deoxygenated versus oxygenated hemoglobin.
a pulse oximeter
whose sensor is attached to a finger, so that the oxygenation of blood flowing through the finger can be determined. See illustration.
Finger oximeter. Pulse oximetry transducer properly placed on a finger. Fold the Oxisensor over the end of the digit. Align the other end of the sensor so that the two alignment marks are directly opposite each other. Press the sensor into the skin. Wrap the adhesive flaps around the digit.

pulse oximeter an oximeter that permits measurement of oxygen saturation in an artery by recording the different modulations of a transmitted beam of light by reduced hemoglobin and oxyhemoglobin as seen during the pulse. A component of the oximeter analyzes the variations in light absorption and provides a readout of the per cent of saturation of the hemoglobin. A saturation above 90 per cent corresponds to a PaO2 of 60 torr or higher. The presence of fetal hemoglobin, carboxyhemoglobin, or intravascular dyes may alter the accuracy of a pulse oximeter. In these instances a SaO2 of 90 per cent may not be associated with a PaO2 of greater than 60 torr.
An instrument for determining photoelectrically the oxygen saturation of a sample of blood.
A device for measuring the oxygen saturation of arterial blood, especially a pulse oximeter.
ox′i·met′ric (-mĕt′rĭk) adj.
A laboratory instrument capable of measuring the concentration of oxyhemoglobin, reduced hemoglobin, carboxyhemoglobin, and methemoglobin in a sample of blood.
oximeter A device for measuring or monitoring the oxygenated fraction of the haemoglobin in the circulating blood. Oximeters use photoelectric methods to detect colour differences in blood of different oxygen saturation. They are valuable aids to safety and are widely used in operating theatres and in intensive care units. See also PULSE OXIMETER.
