A pulse oximeter is an essential medical device used to measure oxygen saturation (SpO₂) and pulse rate in seconds. Whether for home health monitoring, elderly care, or COVID recovery, choosing the right oximeter ensures accurate and reliable readings.
In this expert Q&A guide, we answer the most searched questions about pulse oximeters to help you make the best buying decision.
What Is a Best Pulse Oximeter and How Does It Work?
A pulse oximeter is a small fingertip device that measures the oxygen level in your blood and your heart rate. It works by passing light through your finger to detect how much oxygen your red blood cells are carrying.
What Is the Normal Oxygen Level in a Pulse Oximeter?
The normal oxygen level (SpO₂) is:
✔ 95% to 100% – Normal
✔ 90% to 94% – Low (monitor closely)
✔ Below 90% – Medical attention needed
Maintaining healthy oxygen levels is essential for overall health.

🔹 CE/FDA certified (if available)
Can Pulse Oximeters Detect Breathing Problems?
Yes. Low oxygen saturation levels can indicate respiratory issues such as:
• Asthma
• COPD
• Pneumonia
• Sleep apnea
• Lung infections
Early detection helps seek timely medical care.
Are Cheap Pulse Oximeters Reliable?
Many affordable pulse oximeters under ₹1,000 in India offer good accuracy for daily home use. However, always choose trusted medical suppliers like MyGetWellStore.
How Long Does a Pulse Oximeter Take to Show Results?
Most fingertip oximeters display accurate readings within 5 to 10 seconds.
Can Children Use a Pulse Oximeter?
Yes, children can use pulse oximeters, but ensure the finger fits properly for accurate readings. Pediatric-compatible models are preferred.

What Is a Dangerous Oxygen Level on an Oximeter?
An oxygen level below 90% is considered dangerous and requires immediate medical attention. Levels between 90% and 94% should be closely monitored.
Why Does My Oximeter Show Low Oxygen Sometimes?
Low readings can be caused by:
• Cold fingers
• Poor blood circulation
• Movement during reading
• Nail polish
• Weak batteries
Always sit still and ensure proper finger placement.
Can a Pulse Oximeter Detect COVID or Lung Infection?
A pulse oximeter cannot diagnose disease but can detect low oxygen levels, which may indicate respiratory issues such as COVID-19, pneumonia, or lung problems.
Is 92 Oxygen Level Normal for Elderly People?
An SpO₂ level of 92% is slightly low and should be monitored, especially in elderly people. Consult a doctor if it remains low consistently.
Can Anxiety Affect Oximeter Readings?
Yes, anxiety may temporarily affect breathing patterns, but oxygen levels usually remain normal unless there is an underlying respiratory issue.
Which Finger Is Best for Pulse Oximeter Reading?
The index finger or middle finger usually gives the most accurate readings due to better blood flow.
Final Thoughts
A pulse oximeter is a must-have medical device for every home. It helps monitor oxygen levels quickly, detect health issues early, and provides peace of mind for families.
Choosing a reliable and accurate oximeter ensures better health monitoring every day.
