How to read a pulse oximeter at home?

Using a pulse oximeter at home is straightforward; here's how to do it:

Steps to Using a Pulse Oximeter

Prepare the Device: Ensure your pulse oximeter has working batteries or is properly charged.
Position Your Finger:
- Place your finger on the cushion inside the device as indicated in the reference (Part of a video titled How To Use A Pulse Oximeter - YouTube).
- Make sure it's comfortably in place.
Power On: Once your finger is correctly positioned, press the power button, as also mentioned in the reference (Part of a video titled How To Use A Pulse Oximeter - YouTube).
Wait for Reading: Allow a few seconds for the oximeter to display a reading, it can take up to a minute for a stable reading.
Understand the Display:
- SpO2: This is your oxygen saturation level, expressed as a percentage. A normal range is usually between 95% and 100%.
- Pulse Rate: This is your heart rate, measured in beats per minute.

Normal Readings:
- SpO2: 95% to 100% is generally considered normal for healthy individuals.
- Pulse Rate: Normal varies by age and activity level, typically between 60 to 100 bpm for adults at rest.
When to be Concerned:
- Low SpO2: A reading below 90% is considered low and needs medical attention.
- Very High/Low Pulse Rate: A pulse rate consistently outside of the normal ranges might need medical review.
Factors that may affect readings:
- Fingernail polish may impact accuracy.
- Cold hands may cause inaccurate readings, it may be better to warm your hand up before taking a measurement.
- Movement can also affect readings.

Consistency: Take readings at the same time each day if you're monitoring a condition.
Record Readings: Keep a log of your readings for tracking any changes.
Consult a Doctor: Always consult your doctor for medical advice when needed. The results displayed on an oximeter are not conclusive and may require verification.
