The PO-210B pulse oximeter for children and toddlers measures oxygen saturation and pulse at the finger. Due to its smaller size, the little finger fits perfectly between the measurement sensors, and the measurement site is optimally shaded. Its colorful, child-friendly design makes it appealing to children. It provides reliable measurements of oxygen saturation and pulse rate. The clear, easy-to-read OLED display features large numbers and shows the results within a few seconds. An alarm function with individually adjustable alarm limits is included, as well as a pulse frequency tone for acoustic pulse playback. The screen brightness levels are adjustable, and there are six different display modes. The device is suitable for children aged approximately 3 to 10 years.
