CMS-50B Finger Pulse Oximeter

The 50B is small and lightweight, with low power consumption. You just put your finger into the sensor of the device, and you blood oxygen level (SpO2) will appear on the screen within the first 5 seconds. The quickest device to monitor blood oxygen! It is equipped with an LCD screen and powers off automatically 4 seconds after you pull out your finger to save energy. This oximeter detects SpO2 and pulse rate through the patient's skin and indicates the pulse intensity with a bar graph. The device is ideal for use at home, in major hospitals (including internal medicine, surgery, anesthesia, pediatrics, emergency room, etc.), oxygen bars, and before or after physical activity. The CMS 50B is perfect for spot checking your blood oxygen levels, but is not appropriate for continuous monitoring over 2 hours. The measurement of SpO2 is taken from the arterial pulse, thus sufficient pulsating blood flow is required. For patients with weak pulse due to shock, low ambient/body temperature, major bleeding, or use of a vascular contracting drug, the SpO2 waveform (Pleth waveform) will decrease. In this case, the measurement will be more sensitive to interference, so make sure to keep your hand still on your lap or a surface during use of the oximeter.
