Vital signs (also known as vitals) are a group of the four to six most crucial medical signs that indicate the status of the body's vital (life-sustaining) functions. These measurements are taken to help assess the general physical health of a person, give clues to possible diseases, and show progress toward recovery.
A pulse oximeter probe applied to a person's finger. A pulse oximeter is a medical device that indirectly monitors the oxygen saturation of a patient's blood (as opposed to measuring oxygen saturation directly through a blood sample) and changes in blood volume in the skin, producing a photoplethysmogram that may be further processed into other measurements.

The pulse oximeter is a small device that clips to the body (typically a finger, an earlobe or an infant's foot) and displays its reading, or transfers it to another device. Oxygenated and deoxygenated hemoglobin differ in absorption of light of different wavelengths.
[1] [2] A PPG is often obtained by using a pulse oximeter which illuminates the skin and measures changes in light absorption. [3] A conventional pulse oximeter monitors the perfusion of blood to the dermis and subcutaneous tissue of the skin. Finger pulse oximeter. With each cardiac cycle the heart pumps blood to the periphery. Even though ...

The term "blood gas monitor" is incorrect and confusing, so I moved this page to "pulse oximeter", which is a much more current term. I will adjust redirects. I don't think that the term "blood gas monitor" should redirect here, at least not with out clear information that pules oximeters do NOT measure blood gases.--
The functional oxygen saturation measured by this procedure is the basis for calibrating pulse oximeters. Pulse oximeters cannot be calibrated using physical procedures, but only by directly comparing the reported measurements and the parallel arterial oxygen saturation measured by hemoximetry in a group of healthy subjects.
