Pulse Oximeters

Normal blood oxygen saturation (SpO2) levels typically range from 95% to 100%. Readings between 90% and 94% may indicate mild hypoxemia and should be monitored. Readings below 90% indicate low oxygen levels and require immediate medical attention.

Pulse oximeter prices in India range from ₹800 for basic fingertip models to ₹3,500 for advanced units with additional features like perfusion index and respiratory rate. Handheld professional models range from ₹3,500 to ₹12,000, while tabletop clinical units cost between ₹15,000 to ₹45,000.

Quality fingertip pulse oximeters provide clinical-grade accuracy with ±2% deviation for SpO2 readings between 70-100% and ±2 BPM for pulse rate. Accuracy may be affected by poor circulation, nail polish, cold hands, or movement during measurement.

Pulse oximeters cannot detect COVID-19 directly, but they can help monitor oxygen saturation levels, which may drop in COVID-19 patients. Low SpO2 readings (below 94%) can be an early indicator of respiratory distress and should prompt medical consultation.

Remove nail polish, warm your hands if cold, insert finger fully into the device, keep your hand still at heart level, and wait 10-30 seconds for stable readings. Take measurements when relaxed and avoid movement during reading.
