SpO2 sensors allow for the non-invasive monitoring of how much oxygen patients have in their blood. As there are SpO2 sensors designed to serve different purposes, there are finger sensors, ear sensors, and neonatal sensors. Finger sensors are easy and comfortable to use and therefore frequently used on adult patients. Ear sensors are more useful for patients who have poor blood circulation in the extremities. Neonatal sensors are specially made for babies so that they can get accurate readings most comfortably. Caremed Medical has an extensive range of SpO2 sensors that are useful for healthcare providers all around the world.
