was ist 'pulsoximetrie'?
Definition für
Pulsoximetrie
Oximetrie
Non invasive method of determining oxygen level in blood
|
Pulsoximetrie auch bekannt als:
Oximetrie,
Pulsoximeter,
Transkutane Sauerstoffmessung,
transkutanen sauerstoffsättigung
.
Pulse oximetry is a non-invasive method allowing the monitoring of the oxygenation of a patient's haemoglobin.
A sensor is placed on a thin part of the patient's anatomy, usually a fingertip or earlobe, or in the case of a neonate, across a foot, and a light containing both red and infrared wavelengths is passed from one side to the other.

Pulse oximetry is a non-invasive method allowing the monitoring of the oxygenation of a patient's haemoglobin.
A sensor is placed on a thin part of the patient's anatomy, usually a fingertip or earlobe, or in the case of a neonate, across a foot, and a light containing both red and infrared wavelengths is passed from one side to the other. Changing absorbance of each of the two wavelengths is measured, allowing determination of the absorbances due to the pulsing arterial blood alone, excluding venous blood, skin, bone, muscle, fat, and (in most cases) fingernail polish. Based upon the ratio of changing absorbance of the red and infrared light caused by the difference in color between oxygen-bound (bright red) and oxygen unbound (dark red or blue, in severe cases) blood hemoglobin, a measure of oxygenation (the per cent of hemoglobin molecules bound with oxygen molecules) can be made.
