Pulse oximeters came along in the 1980s as an easy and painless alternative. The device shines a light through the fingertip, seeking out oxygen-rich blood. The more light that’s absorbed, the ...
The needs of the body's blood oxygen may fluctuate such as during exercise when more oxygen is required [5] or when living at higher altitudes. A blood cell is said to be "saturated" when carrying a normal amount of oxygen. [6] Both too high and too low levels can have adverse effects on the body. [7]
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.

An anesthetic machine with integrated systems for monitoring of several vital parameters, including blood pressure and heart rate. Monitoring of vital parameters can include several of the ones mentioned above, and most commonly include at least blood pressure and heart rate, and preferably also pulse oximetry and respiratory rate.

However this equilibration does not occur when the alveolus is insufficiently ventilated, and as a consequence the blood exiting that alveolus is relatively hypoxemic. When such blood is added to blood from well ventilated alveoli, the mix has a lower oxygen partial pressure than the alveolar air, and so the A-a difference develops.
While weight fluctuations in men can be perfectly normal, if they are significant or unexpected it may be cause for concern, according to an expert. Why does my weight fluctuate so much? Skip to ...
