The PO-210B pulse oximeter for children and toddlers measures oxygen saturation and pulse at the finger. Due to its smaller size, a child's finger fits perfectly between the measurement sensors, and the measurement site is optimally shaded. Its colorful, child-friendly design makes it appealing to kids. It provides reliable measurements of oxygen saturation and pulse rate. The clear, easy-to-read OLED display features large numbers and shows 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.
