Which pulse oximeter to choose ?
Share
With more people monitoring oxygen levels at home, choosing the right pulse oximeter has never been more important. Whether you live with a lung condition, you’re tracking fitness recovery, or just want peace of mind, this guide helps you select the best pulse oximeter for your needs – including UK shipping from Healthcare UK™.
Why a Reliable Pulse Oximeter Matters
- A pulse oximeter estimates blood oxygen saturation (SpO₂) and pulse rate – key metrics for lung health, fitness recovery or everyday monitoring.
- Low quality devices may show inaccurate readings which can mislead health decisions. Accuracy is therefore crucial.
Key Standards and Accuracy to Check
When purchasing, you should look for:
- Standards such as ISO 80601-2-61 which outlines accuracy requirements for SpO₂ devices. (Many consumer models omit it.)
- A stated inaccuracy of less than ±4 % for SpO₂ in the 70-99 % range.
- CE marking (for UK/EU) or UKCA mark – demonstrating regulatory compliance.
Which Device Features Should You Prioritise?
- Display readability – clear screen, backlighting, good contrast (especially important for older users).
- Sensor quality – good fit on finger, minimal movement artefacts, suitable for smaller fingers (children).
- Additional features – pulse waveform, perfusion index, alarms for low SpO₂ or high pulse.
How to Use a Pulse Oximeter for Home Monitoring
- Ensure your hands are warm and still – cold or moving fingers can affect accuracy.
- Rest for 2-3 minutes before measurement to stabilise heart rate.
- Place the device on the fingertip and allow the reading to stabilise (typically a few seconds).
- Record your SpO₂ and pulse rate. If readings are consistently low (e.g. SpO₂ < 92 %) consult a healthcare professional.

Frequently Asked Questions (FAQ)
Can a cheap oximeter be trusted?
Not always. Some low-cost models lack proper certification, use inferior sensors or have small displays that are hard to read. For home health monitoring, opt for a device with reliable accuracy and clear interface.
What is a normal SpO₂ reading?
For a healthy adult at rest, SpO₂ normally ranges from 95 %-99 %. Consistently below 92 % may indicate hypoxia and warrants medical attention.
Can I use it while exercising?
Some models are designed with fast response times and programmes for exercise recovery. Make sure the specification mentions sports mode or fast reading for this purpose.
Conclusion
Choosing the right pulse oximeter for home use means focusing on accuracy, usability and trusted certification – especially in the UK market. With the right device from our curated collection at Healthcare UK™, you’re set for confident, reliable health monitoring at home.
