## Questions & Answers

**Q: Will it eat the battery?**
A: Its meant for spot readings really, not left on for hours, as unlike ones in hospitals it is not connected to a permanent power supply. With 2 x AAA batteries it should last a decent time though.

**Q: Is it an nhs approved uk oximeter? can it measure the oxygen level in the blood?**
A: Yes, the oximeter is used to obtain heart rate and oxygen saturation values and it is an NHS approved pulse oximeter.

**Q: Why can't I put oil on my nails?**
A: Because it is easier to get inaccurate readings with dark nail polish or artificial nails, because the probe's sensor light does not count cells correctly through these surfaces. Often, it is difficult to obtain accurate readings if your fingers are cold or have poor blood circulation. After washing your hands, if they feel cold, warm them up and remove the nail polish from one finger.

**Q: Approval procedures for the Food and Drug Administration? ? ?**
A: Yes.
