Frequently Asked Questions
+212 expertsreviewed itVery dark or opaque polish can block the light sensor on any fingertip oximeter, including this one. Light or clear polish is usually fine. If the PI reading looks weak, try a bare finger for the clearest result.
Absolutely. The soft, flexible chamber adjusts to fit smaller fingers comfortably, so both children and adults can check their oxygen levels safely and easily.
Yes. The high-contrast OLED display is built for maximum brightness, so your results stay crystal clear even in dimly lit or completely dark rooms.
The PI reading reflects how strong your pulse is at the sensor. It's a helpful indicator of circulation quality and confirms your measurement is dependable.
OxiVantage measures oxygen using red and infrared light, the standard pulse oximetry method. The PI reading lets you confirm a strong signal on any skin tone before trusting the number. Many COPD patients use it for daily spot checks.
Cold hands lower blood flow to your fingertip, which can lower the PI reading. Warm your hands or rub your fingers for a few seconds, then check again. The pulse wave on screen shows you when the signal is strong enough to trust.
Small shifts in finger position or grip pressure can change your number by a point or two between checks. Watch the pulse wave: a steady, strong wave means you can trust that reading, a weak or jumpy one means it's time to reposition.
It runs on standard replaceable batteries, so there's no cord or charging dock to manage. The auto-sleep feature shuts it down after eight seconds of inactivity, helping a single set of batteries last for weeks of regular spot checks.
