• Observing oxygen saturation over time
• Warning to critically low oxygen levels, specifically in newborns
• Giving peace of mind to patients with cardiovascular conditions and chronic respiratory
• Determining the requirement for supplemental oxygen
• Checking oxygen saturation levels in patients under anesthesia
• Specifying dangerous side effects in people consuming drugs that affect oxygen saturation or breathing

What affects readings of pulse oximeters?

• Low blood pressure
• Anemia
• Skin with more pigment

How would you define a pulse oximeter?

A pulse oximeter is a small device used for monitoring the pulse rate and the oxygen saturation level in the body. This noninvasive tool clips onto a fingertip to measure how much oxygen is in a person’s blood. The device is often used in hospitals and clinics and can also be bought to use at home.

How blood oxygen levels are measured by a pulse oximeter?

A pulse oximeter works by passing a light beam through the fingertip (or earlobe), and then measuring the reflection of the light, how much light is transmitted through or reflected off from the sensor (present in the oximeter) on the other side. Then, by using a mathematical equation, the pulse oximeter is able to measure how much oxygen is present in the blood.
