Pulse oximeter

What is a pulse oximeter?

A pulse oximeter measures how much oxygen is in someone’s blood. It is a small device that clips onto a finger, or another part of the body. They are used often in hospitals and clinics and can be bought to use at home.

Pulse oximetry is essential for assessing oxygen saturation during respiratory compromise and for monitoring patients undergoing anaesthesia, who are critically ill, or whose condition is rapidly evolving. More immediately, during the ongoing COVID-19 pandemic, silent hypoxia

What are normal readings?

A normal level of oxygen is usually 95% or higher. Some people with chronic lung disease or sleep apnea can have normal levels around 90%. The “SpO2” reading on a pulse oximeter shows the percentage of oxygen in someone’s blood.


  • Measuring range for SPO2: 70-100%
  • SpO2 measurement accuracy: 91%–100%, ±1%; 70%–89%, ±2%; ≤70%, unspecified.
  • Storage temperature: -20°C to 50°C
  • Storage relative humidity: 10% – 95%. No condensation
  • Operation temperature: 5°C to 40°C
  • Operation relative humidity: 35% – 75%
  • If you have any questions regarding any of this information, please contact our Technical Service Department.
  • Latex Free. No toxicity, which meet biology compatibility request.

Calibrating the M-50 series Sensor

The functional tester cannot be used to assess the accuracy of the Oximeter.

Index2 that made by Bioteck company is a function tester. The user can use this function tester to measure the Oximeter.

The test methods used to establish the SpO2 accuracy is clinical testing. The Oximeter used to measure the arterial haemoglobin oxygen saturation levels and these levels are to be compared to the levels determined form arterial blood sampling with a CO-Oximeter.
