Clinical Accuracy

This device’s SpO2 accuracy is supported by a clinical study conducted on 12 healthy volunteers (6 males and 6 females, aged 18–45) with diverse skin tones (2 black, 8 light, 2 white). Measurements were compared against a secondary standard pulse oximeter, ensuring reliability across the 70%–100% SpO2 range. Note: Pulse oximeter readings can vary due to statistical distribution, with approximately two-thirds of readings falling within ±Arms of the reference value.

Pulse rate accuracy has been validated using a patient simulator, providing root-mean-square precision between the measured value and the simulator’s set value.

Why Choose This Oximeter?

This pulse oximeter is an excellent choice for individuals seeking accurate and easy-to-use health monitoring devices. Its clinically validated performance, lightweight design, and long battery life make it suitable for both home and clinical environments.

For optimal results, ensure the device is used as instructed, and consult your healthcare provider if you have concerns about your readings.
