Usage Precautions for Medical Grade Fingertip Pulse Oximeter

The Medical Grade Fingertip Pulse Oximeter is a small medical device used to measure the oxygen saturation in the human bloodstream. It is usually used to monitor patients with respiratory diseases, such as asthma or chronic obstructive pulmonary disease (COPD), as well as patients undergoing anesthesia or postoperative recovery.

Before using the device, it is important to make sure the instrument is in good condition and fully charged. Nail polish and toenail fungus can affect the accuracy of blood oxygen saturation monitoring, and should be avoided if possible. Finger tremors can also have an impact, so wait a few seconds until the pulse waveform stabilizes for a relatively accurate reading. In winter, due to poor blood circulation, the temperature of the fingertips may be lower, which can cause inaccurate readings or even no reading. It is recommended to wait for the body to warm up before conducting the test. If the blood oxygen saturation drops significantly (usually below 93%) when you are not receiving Medical Grade Fingertip Pulse Oximeter, you should seek medical attention immediately.

Thoroughly wash your hands with soap and water and allow them to dry completely. Turn on the oximeter, place it on your finger, and ensure it fits comfortably. Wait a few seconds for theMedical Grade Fingertip Pulse Oximeter to read your pulse and blood oxygen saturation. Read the result on the screen. Blood oxygen saturation between 95% and 100% is considered normal.
