        The fingertip oxygen meter can measure the oxygen level. By emitting light waves from above that are around the nail. through the finger down to the photoreceptor on the other side of the user's fingertip to measure hemoglobin that binds to oxygen in the blood Then it was taken to calculate the oxygen concentration in the blood. out as a percentage (percentage) and displayed on the screen of the device with the following measurement values: (reference information Lanna Hospital)
