The OXM-A2-1 children's fingertip pulse oximeter measures blood oxygen saturation, pulse rate and strength, and perfusion index. Readings are displayed on an OLED screen within 8 seconds, with SpO2 accuracy of ±2% in the 70%–99% range.

Measurement starts at the press of a button, and the device switches off automatically after 8 seconds of inactivity. It fits different finger sizes, including the thumb or big toe, and features an alarm for low or high oxygen levels and heart rate.
