A finger pulse oximeter is a small, hand-held medical device that
measures the oxygen saturation of a patient's blood as well a patient's
heart rate without even trying. It clips onto the end of the finger,
over the nail,and measures the hemoglobin saturation. The oximeter
measures the difference in light absorption between the oxygenated
hemoglobin molecule and the deoxygenated version. The pulse oximeter
measures the saturation of the blood in relation to normal levels,
considered to be from 95 to 100% saturation.
Select the appropriate type of pulse oximeter that fits your needs.
There are several different styles of pulse oximeters can range from less
than a hundred dollars to a couple of thousand. Oximeters range in
capabilities and features like perfusion index, plethysmograph, or color
display may not be available on all models. Remember that a higher
price doesn't necessarily equal higher quality. You need a device that
will give you accurate, reliable oxygen saturation readings and pulse
