A fingertip pulse oximeter estimates oxygen saturation, commonly shown as SpO2, and measures pulse rate. Display layout, power supply and supported functions vary between models, so start with the instructions supplied with your device.
Prepare before measuring
Use the device in the conditions specified by the manufacturer. Keep your hand still and allow the reading to settle. Cold fingers, movement, poor circulation, nail coatings and other factors can interfere with measurement. Accuracy can also vary with skin pigmentation and the circumstances of use.
Compare useful features
Look at display size, viewing orientation, brightness and battery requirements. Some models offer Bluetooth transfer or additional recording functions. Confirm these features on the exact product page and check any app requirements separately.
Look at the whole picture
A single number does not explain how a person is feeling. Follow guidance from your healthcare professional about interpreting your readings and any personal action plan. Do not delay seeking medical care because of a reassuring device reading when symptoms are concerning.
Care for the device
Clean and store the sensor according to its manual. Avoid immersing it in liquid unless the manufacturer explicitly allows it, and remove batteries for extended storage when instructed.
