A finger pulse oximeter quickly and easily measures a patient’s blood's oxygen saturation and heart rate. These kinds of devices have to be attached to well perfused areas like earlobes, feet, or fingers. Finger pulse oximeter models have been proven to be specially easy to use and reliable. It's simple design and handling makes them perfect for using in hospitals, doctor’s offices, or even privately at home. Patients that use an oxygen supply machine or those with chronic lung diseases, asthma, lung cancer, or anaemia will find these instruments really helpful for self-monitoring their own values.
In the past, health professionals could only measure a patient’s blood oxygen supply by time-consuming examinations that included blood withdrawal. But in the 1980s, the pulse oximeter was invented. These devices allow for a non-invasive procedure that can detect potential oxygen deficiency before there is any cyanosis.
Using a finger pulse oximeter is fairly easy, non-invasive, and really quick. Simply place the device on the patient’s or your own fingertip. Their clips have a light source that emits light beams in different wavelengths which penetrate the skin. The sensor, which is on the clip’s other side, measures which light waves were not absorbed based on the blood’s colour. Red light means the haemoglobin is saturated, dark/burgundy red means the haemoglobin is not saturated enough. The photodiodes located at the oximeter’s bottom part measure the strength of the incoming light. These two values combined are used to determine the Spo2 oxygen saturation. The values determined should normally be between 93% and 99% and not fall below the 90% mark.
When used correctly, a finger pulse oximeter usually delivers very accurate results. However, there are a number of factors that can influence the shown data. Some of them are:
