We look at eight pulse oximeters you can buy and how to make the most of these devices.

What is a pulse oximeter?

A pulse oximeter is a small device that measures your oxygen saturation level, or how much oxygen is in the blood.

Light emitting diodes, or LEDs, on the inside of the pulse oximeter probe give off a red light, or more than one color of light. The light shines through the tissues of your fingertip, and the sensor on the other side picks up the light that comes through.

Pulse oximeters measure how much light comes through your finger to estimate how many of your blood cells are carrying oxygen. This reading is called oxygen saturation, or SpO2, and displays a percentage.

A small screen on the probe displays a percentage, which estimates how much blood oxygen is in your limbs (arms, hands, legs, and feet) or other body parts.

Clinically tested

A very small clinical study from 2016 tested six low cost home pulse oximeters and found that two brands had devices with an error rate of less than 3 percent: the Contec CMS50DL and Beijing Choice C20.

None of the oximeters in the study had digital or analog displays, so the study participants recorded readings manually at the time.

A major difference between the models tested in the study and the two recommended here is that the current models from both brands have displays to show you your readings.

What can affect pulse oximeter readings?

  • Skin color. Skin with more pigment may cause some pulse oximeters to give slightly higher readings.
  • Local Chinese Brand : Local Brand doesn’t give proper reading and creates panic.
  • Conditions that cause circulation problems. Poor blood circulation in your hands and fingers may cause lower readings.
  • Cold hands. Having cold hands may cause lower readings.
  • Wet skin. Water or sweat on the skin may reflect the light and affect the measurement.
  • Thick fingernails. Thick nails can block the light penetration and may cause lower readings.
  • Fingernail polish. Black, blue, and green nail polish may cause significantly lower readings.
  • Bruises or tattoos on the fingertips. Both may cause inaccurate readings. Try choosing a different finger or limb for a more accurate reading.
