Many FDA-cleared models on Amazon offer accuracy within ±2% of your actual SpO₂ level. For best results, use the device on a warm finger, while resting, and without nail polish or movement.
How do I use a fingertip pulse oximeter?
Simply place the oximeter on your fingertip, press the power button, and wait 5–10 seconds for your SpO₂ and pulse rate readings to appear on the screen.
Who should use a pulse oximeter?
Ideal users include:
People with respiratory or cardiovascular conditions
Athletes and high-altitude climbers
COVID-19 patients for home monitoring
Sleep apnea sufferers
Are pulse oximeters reusable?

What features should I look for in a good pulse oximeter?
Large, bright display (OLED or LED)
SpO₂ and pulse rate readings
Battery level indicator
Auto shut-off
Carrying case or lanyard
App connectivity (in smart models)
