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. ## Frequently Bought Together - Pulse Oximeter, Blood Oxygen Saturation Monitor, Heart Rate Monitor OLED Display with Alarm for Instant and Accurate Measurement Pulse Rate and SpO2 Level, with Battery and Lanyard (Blue) - Blood Pressure Monitor CE Approved UK, Vimmk Upper Arm Blood Pressure Machines for Home Use Accurate BP Cuff LED Backlight Display Heart Rate Detection 2x120 Records, Cuff 22-40cm --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.sn/products/449385363-pulse-oximeter-blood-oxygen-saturation-monitor-heart-rate-monitor-oled](https://www.desertcart.sn/products/449385363-pulse-oximeter-blood-oxygen-saturation-monitor-heart-rate-monitor-oled) --- *Product available on Desertcart Senegal* *Store origin: SN* *Last updated: 2026-09-14*
