The color determines your blood oxygen level - bright red blood has more oxygen, while dark red blood has less. Algorithms use this data to calculate the color of your blood. Photodiodes then measure the amount of light reflected. During a blood oxygen measurement, the back crystal shines red and green LEDs and infrared light onto your wrist.

For example, in the Apple Watch Series 6 and above, the optical heart sensor has also been redesigned to add blood oxygen measurement capabilities. Some smartwatches can measure your blood oxygen saturation level. Image of a Pulse Oximeter on a person's finger showing Blood Oxygen Level (SpO2) of 97% and pulse rate (PR) of 92 beats per minute. Remove any fingernail polish on that finger.Ĭontinued below image.

When placing the oximeter on your finger, make sure your hand is warm, relaxed, and held below the level of the heart.

Write down your oxygen levels with the date and time of the reading so you can easily track changes and report these to your health care provider.

Wait a few seconds until the reading stops changing and displays one steady number.

Sit still and do not move the part of your body where the pulse oximeter is located.

Always follow the manufacturer's instructions for use.

To get the best reading from a pulse oximeter:

NOTE: Several factors can affect the accuracy of a pulse oximeter reading, such as poor circulation, skin pigmentation, skin thickness, skin temperature, current tobacco use, and fingernail polish. They are used often in hospitals and clinics and can also be bought to use at home. The pulse oximeter can estimate the amount of oxygen in the blood without drawing a blood sample. Oxygen saturation gives information about the amount of oxygen carried in the blood. Measuring Blood Oxygen Level Pulse OximeterĪ pulse oximeter is a small device that clips onto a finger, an earlobe, or an infant's foot and uses light beams to estimate the oxygen saturation of the blood (how much oxygen is in the blood) and the pulse rate. Your blood oxygen level is the percentage of the amount of oxygen circulating in your blood. Low blood oxygen levels can lead to severe health conditions. Your body needs a certain amount of oxygen to function correctly. The amount of oxygen in your blood is called your blood oxygen level (blood oxygen saturation). When you breathe, oxygen goes through your lungs and enters your bloodstream. Arterial blood oxygen levels below 80 percent may compromise organ function, such as the brain and heart, and should be promptly addressed. If the level is below 90 percent, it is considered low and called hypoxemia. Normal arterial blood oxygen saturation levels in humans are 97-100 percent. The human body requires and regulates a very precise and specific balance of oxygen in the blood. Oxygen saturation is the fraction of oxygen-saturated hemoglobin relative to total hemoglobin (unsaturated + saturated) in the blood. In medicine, oxygen saturation, commonly referred to as 'sats', measures the percentage of hemoglobin binding sites in the bloodstream occupied by oxygen. Oxygen is carried around in your red blood cells by a molecule called haemoglobin. Oxygen saturation can be determined either outside the body via pulse oximetry or invasively with the aid of a blood gas analysis. Among other things, it provides information about the functional capacity of the lungs and the effectiveness of oxygen transport in the blood. Oxygen saturation (sO2) refers to the percentage amount of oxygen in the blood.
