To get the most accurate readings from your REACTHEALTH PO2BLK Pulse Oximeter, correct finger placement is key. Here's how to position your finger properly: First, insert your finger between the rubber cushions of the device. Make sure you are following the illustration in your device's manual (specifically, Figure 7). Your finger needs to be deep enough within the device for the sensors to work effectively. Avoid moving or shaking your finger while the device is taking a measurement to ensure the readings remain stable. It's also important to make sure the SpO2 sensor and the photoelectric receiving are aligned with the arteriole in your finger for the most accurate results. Keep in mind that nail polish or artificial nails can sometimes interfere with the readings, so it's best to avoid using the device on fingers with these on. Following these steps will help you get reliable and accurate measurements with your REACTHEALTH PO2BLK Pulse Oximeter.
