How Can I Take My Oxygen Level at Home?
You can easily check your blood oxygen levels at home using a pulse oximeter. This small, clip-on device measures the oxygen saturation in your blood (SpO2). Optimal levels typically range from 95% to 100%.
- Acquisition: Purchase a pulse oximeter from a pharmacy or online retailer.
- Usage: Follow the manufacturer's instructions carefully for accurate readings. Generally, you clip the device onto a fingertip and wait for a reading.
- Readings: Oxygen levels between 95% and 100% are considered normal for most people. [Source: Pulse oximeters are a quick and painless way to check your levels. Oxygen levels between 95% and 100% are optimal for most people.]
- Accuracy: Ensure you use the device correctly to get the most accurate readings, and consult with your healthcare provider if you have any questions.

- Limitations: Remember that pulse oximeters are not a substitute for professional medical advice. If you have concerns about your oxygen levels, consult your doctor. [Source: “In normal times, unless a patient has true lung disease, there is no need for them to use pulse oximetry monitoring,” ]
Alternative Methods (Under Development)
Research suggests that future technologies may allow you to monitor blood oxygen levels using your smartphone's camera and flash. This is currently under development, but offers a promising non-invasive alternative for future home monitoring.

Important Considerations
- Always consult your doctor before using any home monitoring device, especially if you have pre-existing health conditions.
- Regularly checking your oxygen levels at home without medical supervision is generally not recommended unless instructed by a healthcare professional.
