The large and brilliant TFT screen makes the NANOX10 a valuable tool in daily practice. With a new set of AA alkaline batteries, the device works for about 40 hours, operating at full backlight. If you compare it with other instruments of its class, the major differences are the adjustable alarm limits with optical and audible alarm indicators, the memory and the saturation dependent pulse tone. The pulse tone can be switched off and has an adjustable volume. For documentation purposes, the stored SpO2 and pulse values can be transmitted to a printer or to a PC by using the integrated MiniSD card socket. Patient safety is guaranteed by the infrared transmission. The internal memory capacity is 55 hours, for SpO2 and pulse values, while the optional SD has nearly unlimited storage capacity.
