Radius PPG wireless receiver R25. A portable, battery-powered, electronic device designed to detect hypoxia(oxygen deficiency at the tissue level) via the transcutaneous multiwave measurement and display of carboxy-haemoglobin saturation (SpCO) and typically other related parameters such as haemoglobin oxygen saturation (SpO2), methaemoglobin saturation (SpMet), and haemoglobin concentration (SpHb); pulse rate and haematocrit may also be calculated. A light-emitting diode (LED) and a receiving detector in a probe applied to a body site (e.g., a fingertip) are used to make multiwave measurements using spectrophotometry. The device is used in healthcare settings or the home, often to evaluate carbon monoxide poisoning. Packaging: 1/ea
