Pulse Oximeters are designed to monitor and measure an individual's SpO2, Pulse Rate, and Perfusion Index. Measuring and tracking this personal health data enables a user to assess and make informed decisions when it matters most.
Pulse oximeter’s measure the percentage of oxygen in red blood cells. This is also known as oxygen saturation. Oxygen saturation or Sp02, is used as an indicator for measuring how effectively oxygen is being transferred throughout the human body.
Pulse oximetry uses a clip-on or wrap around sensor in conjunction with a pulse oximeter, to pass infrared light through the blood in the finger, toe, or earlobe. The infrared light is able to calculate the differences in light absorption. That difference is then interpreted by the device and displayed by the pulse oximeter as SpO2 (oxygen saturation).
See How to Interpret Pulse Oximeter Readings.
Typically, an oxygen saturation level of 95 – 100 is considered normal for most healthy individuals. An oxygen saturation below this range for an extended period of time can put strain on both the heart and brain. This can result in long term health consequences and is something that should be immediately addressed with your physician.
Please note, those with heart or respiratory conditions may have a lower oxygen saturation than what would typically be considered normal. It is important to keep in mind that pulse oximeters are only meant to be used as a measurement and or health monitoring tool. They are not intended for diagnosis or treatment of a medical conditions. Always consult with your physicians before any preventive action.
