What is the correct way to position my finger in the REACTHEALTH PO2BLK Pulse Oximeter?

[McVictoria]

Achieving accurate readings with your REACTHEALTH PO2BLK Pulse Oximeter depends on proper finger placement. Here's how to position your finger correctly: First, insert your finger between the rubber cushions of the device. Make sure your finger is aligned as shown in the manual's illustration, specifically Figure 7. Your finger should go in far enough for a good reading. During measurement, keep your finger still to avoid shaky readings. It's important that the SpO2 sensor and the photoelectric receiving tube are correctly aligned with the arteriole in your finger for best results. Also, avoid using the device on fingers with nail polish or artificial nails, as these can impact the accuracy of the reading. By following these steps, you will be able to get the most accurate results with your REACTHEALTH PO2BLK Pulse Oximeter.
