With each heart beat the fluctuation of blood results in a color change in the fingertips. digiDoc Technologies use sophisticated software to analyze these changes and translate them into meaningful information.

BPM

Beats Per Minute is an approximation of the number of heart beats per minute - ie. the Heart Rate. This increases with physical or emotional stress and decreases with rest. The Pulse Oximeter is very susceptible to changes in Heart Rate and will therefore wary within a few beats. The app can measure Heart Rates between 50 and 180 BPM.

SpO2

An approximation of the blood oxygen saturation. This value will decrease with lower oxygen levels (e.g. asphyxiation, hypoxia, or anemia). The app measures SpO2 values of 93% and above.

Sources of error

Cold fingers, total darkness, tremors, and irregular heart beats off-set the measurements. Also, be sure to follow the App Instructions and read the FAQ in order to get the most accurate results. Low signal tests and SpO2 values below 93% are presented as LowSig. Tap STOP then START to redo the test.

Intended use

The Pulse Oximeter app is for use by sports users who are interested in knowing their blood oxygenation level (SpO2) and Heart Rate. The Pulse Oximeter app is NOT INTENDED FOR MEDICAL USE. The Pulse Oximeter app can be used in a wide range of settings, including between exercises, running, hiking, and in relaxation management.
