Medically, measuring Oxygen Saturation is termed Oximetry due to the use of a pulse oximeter which uses infra red light to and spectrophotometry based principles to estimate the level of O2 bound to haemoglobin in the blood when sat on a peripheral extremity such as the toe, finger or nose.
Oxygen saturation, the percentage of hemoglobin oxygen binding sites that are occupied by an oxygen molecule, is usually measure with a pulse oximeter (also spelled oxymeter). This is a device that measures the absorption of specific wave lengths or red and ultraviolet light and compares their ratios to determine the saturation.
There are two main ways we measure blood oxygenation. The invasive way is by drawing an Arterial Blood Gas. The other method, which is non-invasive is the Oxygen Saturation or O2 Sat method. This is done with a clip on the finger or ear, or even a probe on the head.
The pulse oximeter sends red and infrared light through a spot that has a lot of blood flow such as a finger. A sensor on the other side measures how much light was absorbed, and in what wavelengths, and uses that information to calculate the comparative concentrations of oxygenated and deoxygenated blood.
Oxygen saturation describes the extent the to which hemoglobin in the red blood cells is saturated with oxygen.
90-100%.
Anything below 90% saturation is considered hypoxic.
Oddly enough, the blood haemoglobin oxygen saturation.
pulse oximeter
Maybe you mean pulse oximetry. It is the measurement of oxygen in your blood. It is measured when they put that clip on the tip of your finger.
Pulse oximetry is the procedure for measuring oxygen saturation or level of oxygen in the blood. It is non-invasive and painless.
To determine the oxygen saturation of hemoglobin.
SPO2 or pulse oximetry
There are several sites that one can find more information about pulse oximetry. These sites include the pulse oximetry page of Wikipedia, World Health Organization, and Pulse Ox.
Noninvasive ear or pulse oximetry for oxygen saturation; single determination
The need for supplemental oxygen is determined by inadequate oxygen saturation, indicated in blood gas measurements, pulse oximetry, or clinical observations.
Pulse oximetry measures the amount of oxygen that is being perfused in a person's blood. It is important in individuals with impaired lung function to be sure that their body is getting enough oxygen. It is an excellent tool to be sure that a person is breathing effectively, because if a person's oxygen level drops too low, they can lose consciousness, have brain damage, and eventually enter into respiratory failure and die.
A pulse oximetry (pulse ox) is a small clothes pin looking piece of equipment, usually placed on the patients finger, used to measure the amount of oxygen in the blood. The pulse ox. is noninvasive, very inexpensive, readilyavailable and it provides instant results. If a pulse ox. reading is low then the caregiver would likely apply oxygen to the patient. If it is a high reading the caregiver would likely remove or decrease the amount of oxygen the patient is on. Because there are factors that can interfere with an accurate reading, there are other ways to test the oxygen levels in the blood.
upper arm
First thing straight, you misspelled oximetry. Second thing is the definition of pulse oximetry is a noninvasive method allowing the monitoring of oxygenation of a patient's hemoglobin.
