Frequently Asked Questions
- Is a home pulse oximeter a diagnostic device?
- No. It is a wellness monitoring tool for spot-checking oxygen saturation and pulse at home. Share unusual or low readings with your doctor rather than self-treating, and do not use a home reading to decide against seeking care.
- What makes readings inaccurate?
- Cold hands, nail polish and poor circulation all reduce accuracy, and fit can be loose on very small or very large fingers. Warm the hand, remove polish and stay still — an unreliable reading is worse than no reading.
- How quickly does it give a reading?
- About 10 seconds, with one-button operation and a large LED display facing the user, which matters for someone reading it themselves. It ships with two AAA batteries, a silicone cover and a lanyard, with a 1-year warranty.
