The purpose of a pulse finger oximeter is to monitor the oxygenation of a person’s hemoglobin. This effectively measures the amount of oxygen in your blood at tissue level.
A person’s need for oxygen is the most essential element for life as no-one thrives in the absence of oxygen. Hence the use of the finger oximeter whether it be in hospital in critical care or at home during the night.
There are several different styles of pulse oximeters, from the large models used in hospitals, to handheld units and portable fingertip oximeters.
There are also non-medical oximeters. One use is for pilots as hypoxia is a major concern for pilots who fly non-pressurized airplanes. Non-medical oximeters are essentially the sport versions of pulse oximeters and they are designed to meet the needs of the aviator markets and high altitude performance sports. They often use the fingertip oximeter in high-altitude situations as it can be relied upon by pilots and anyone else working under such environments such as mountain climbing and extreme sports.
They are designed to provide the correct blood oximetry and pulse rate measurement while they are in motion. This makes it perfect for pilots, who can receive inaccurate readings from some other oximeters under conditions of high-altitude and motion artifact.
The finger oximeter is a self-contained pulse oximeter incorporating the electronics and the sensor into one unit.

This pocket size digital pulse fingertip oximeter is very compact, and the unit s placed on the fingertip. It then shines two beams of light through the tissue of the fingertip to sort out the color of the blood and determine the oxygen level in the hemoglobin, the pulse rate and pulse strength measurements.
Finger pulse oximeters utilize their algorithms in a very handy, pocket size solution that provides accurate SpO2, pulse rate and pulse strength measurements on people aged from infants to adults. This digital fingertip oximeter provides clinicians with quick, accurate readings of oxygen saturation, pulse rate, and pulse strength.
This lightweight finger pulse oximeter combines the broad functionality of a standalone unit with the flexibility of a hand-held instrument, yet it is compact enough to fit in the palm of your hand.
Finger pulse oximeters provides exceptional monitoring performance and enable the device to offer unique sensors that address specific clinical challenges. The pulse oximeter remains a valuable tool in the care of intensive care patients, but an awareness of its limitations is an important component of enhancing the quality of care.
