A pulse oximeter, also known as a "portable finger pulse oximeter", can be easily clamped on the finger and detects the pulse of the artery to determine the oxygen percentage and heart rate in the blood. Blood oxygen testing is a very low-cost rapid testing method. According to the different absorption ratios of oxygenated hemoglobin and reduced hemoglobin to different wavelengths, the body can be quickly detected without damage. The oximeter commonly used in many hospitals is a finger clip type. Clamp it on your finger for a minute to produce blood oxygen readings. Normal blood oxygen saturation is higher than 98%. If it is less than 90%, it can be considered dyspnea.
