A Pulse oximeter is a unit that monitors oxygenation of blood by measuring the percentage of haemoglobin saturated with O2. It is attached to the finger or ear lobe and measures the blood flow past a computerized probe in the meter.
A sound or graph is usually displayed to show each pulse beat. 650nm & 805nm are the wavelengths of light usually utilized in an oximeter’s probe to record absorption and saturation of the haemoglobin in a patient’s blood. Oxygenation in the blood is measured by this saturation level measured. Slow blood flow may introduce problems in normal pulse oximeter functions due to the units mechanism of measuring blood flow.
Several situations may cause a pulse oximeter to become inaccurate. Vasoconstriction and Venous congestion have been known to negatively affect readings. Some more less scientific causes of bad readings are due to bright overhead lights and nail varnish. Another cause of mis-readings can come in the form of there being carbo-xyhamoglobin (methaemglobin) in the blood being metered; because a pulse oximeter is unable to distinguish between types of haemoglobin.
In procedures requiring anaesthesia, pulse oximeters are put to use in monitoring oxygenation in blood as well as pulse rates. During situations of intensive care such as mechanical ventilation, pulse oximeters have been successfully used in the detection of oxygenation related problems before they manifest. Oximetry can also be used to analyze the efficiency of oxygen therapy.
Monitoring oxygenation in the blood haemoglobin is the primary function of a pulse oximeter as previously discussed. Oximeters of this type, can not and are not designed to measure, record or detect oxygen metabolism. The process of Oxygen metabolism requires carbon dioxide level data.
Operating aircraft in a non-pressurized cabin is a perfect example of an alternative use of a portable pulse oximeter that can be used to measure the amount of supplemental oxygen a pilot may need at varying altitudes. For extreme climbers and athletes, a decrease in oxygen in the blood may occur in the process of scaling a mountain or performing an exercise or sport at a high exertion level. In these cases, a portable pulse oximeter can be useful to ensure that oxygen levels in the blood are at optimal levels for continued performance without endangering the individual. Other applications for pulse oximeters have been developed.
A major development is the measuring of blood volume loss with pulse oximeter readings. The algorithm created attributes a correlation between oxygenation in blood haemoglobin and blood volume measurements. In home use of pulse oximeters have become popular and units can be found for sale at affordable prices. There are many companies like Nonin, Nellcor, and Checkmate that offer pulse oximeters for sale to the general public in the form of a portable oximeter, finger pulse oximeter, or a digital pulse oximeter.
