A Little About the Science of Oximeters

All pulse oximeters for sale work in the same manner.  They all have a detector, a processor and a display of some type.  In the case of mobile fingertip oximeters those 3 elements are combined in a single compact unit that is small and lightweight enough to place on the conclusion of a finger.

A pulse oximeter operates by detecting the oxygen saturation of the oxygen carrying hemoglobin in the blood.  It does this by detecting the specific colour of hemoglobin molecules in arterial blood.  The colour of hemoglobin varies depending on how much oxygen it is carrying.  Almost all oximeters have a detector into which a fingertip is added.  Less commonly, a toe, an earlobe or nose may be the point of detection.  Light is shone through the fingertip and a photo detector reacts to fluctuations in the light after it’s passed through this translucent tissue.

This information is passed to a computer chip that uses it to ascertain the colour of the hemoglobin molecules in the blood and also changes in blood circulation.  By detecting changes in blood circulation due to pulse surges the oximeters can distinguish arterial blood from different tissues.  The readings are displayed on the display of the oximeter as percentage oxygen saturation in the blood (SPo2) and pulse rate (beats per second).

Medical Uses

Pulse oximeters have become increasingly used in medical settings and are used routinely in hospitals throughout operation and in the healing room.  They offer you a fast, non-invasive and painless method to confirm the oxygen saturation of the blood that gives a good indication of lung and circulatory function.  Their ease of use and the invaluable information they provide has led to more widespread use in recent years.

A Valuable Self Assessing Device for Those with Lung and Cardiac Conditions

Battery operated, portable models are now available, a fraction of the magnitude of operative components, nevertheless offering reliability and accuracy at affordable rates.  Nowadays anyone with a health problem this type of COPD or asthma may check on their illness throughout day to day activities.  This can offer reassurance and also determine if their prescribed medication or oxygen therapy should be used.  This permits patients to report back to their doctor if needed, who will be able to advise further.

Other Programs for Pulse Oximeters

Pulse oximeters are generally used by individuals with a condition which leads to shortness of breath that often means they’re lacking oxygen in the blood.  But there are numerous versions of pulse oximeters for sale suitable for different applications like sport or at elevation where it’s important to track the oxygen saturation of the blood.

As elevation increases air gets thinner, so there’s less and less oxygen to breath in every lungful of air.   In the same manner as a man whose lungs do not work correctly may not have sufficient oxygen in their blood, a typical person can suffer similar symptoms at elevation.

Pulse oximeters are a useful and important part of equipment for these tasks:

Sport at high elevation and high-altitude training.

Mountain climbers.  Hypoxia whilst climbing can be extremely dangerous.

Pilots of unpressurized aircraft such as small planes, helicopters, gliders, micro lights etc..  It’s particularly important to monitor oxygen levels in this case as passing out may have disastrous consequences if at the controls of an aircraft.

Free breath and diving hold coaching.  SpO2 can be tracked for security and to document improvements in lung performance because of training.

Some facets of sport instruction especially simulated altitude training such as intermittent hypoxic training. During sport when the patient has a formerly diagnosed lung illness.
