SpO2 stands for Peripheral capillary oxygen saturation. It is a term that is used to evaluated the level of blood oxygen saturation. SpO2 Oxygen sensor or Pulse oximetry is a non-invasive method for monitoring a person’s O2 saturation. In its most common application mode, a sensor device is placed on a part of the patient’s body, usually on a finger or in a earlobe. The device passes two wavelengths of light through the body part to a photodetectors.
It measures the changing absorbance at the wavelengths and allow it to determine the absorbance due to the pulsing arterial blood alone, excluding venous blood, skin, muscle, bone and nail polish. Reflectance pulse oximetry is used as an alternative to transmissive pulse oximetry described above.
The latest Samsung flagship devices has a SpO2 Oxygen Sensor (Pulse Oximetry). Latest devices like Galaxy S5 and Galaxy Note 4 has a similar sensor and an official app that helps you to measure your heart rate and blood pressure. This is a very helpful feature and all people want to have it on their device. Not all Galaxy Note 4 devices come with a pulse oximetry sensor, so before buying a new Galaxy Note 4 check the list below to see which device has that sensor.
