DEVICE: Nonin (00849686073492)

An electrically-powered photoelectric device designed for the transcutaneous measurement and display of haemoglobin oxygen saturation (SpO2). The signals are produced by light-emitting diodes (LEDs) and received by a photodetector. The device displays the SpO2 values and may also measure/display pulse rate. It is typically applied to the fingertip or around the wrist, may be single-component (with built-in probe) or multi-component (includes external probe), and may in addition wirelessly transmit measurements to a receiving location (e.g., central station, bedside monitor); it is intended to be operated by laypersons and healthcare providers.

A mains electricity (AC-powered) photoelectric device that noninvasively measures the brain tissue blood oxygen saturation and venous oxygen saturation in the brain. It is typically used as an adjunct monitor for the regional haemoglobin oxygen saturation of blood in the brain of a paediatric or adult patient. It uses a cerebral sensor(s) having a light source and photodiode detector that is/are placed on the scalp/head. Position-1 detector detects infrared light absorption of extracranial blood and position-2 detector detects infrared light absorption of cerebral blood. Cerebral oxygenation is calculated by subtracting the absorption measured at site 1 from that measured at site 2.

A mains electricity (AC-powered) photoelectric device intended for the continuous transcutaneous measurement and display of haemoglobin oxygen saturation (SpO2). The signals, typically produced by light-emitting diodes (LEDs) and a receiving detector in a probe, or directly built-in, are used to make the measurements using the principle of spectrophotometry. The oximeter displays the SpO2 values and may calculate/display other parameters, e.g., pulse rate, electrocardiogram (ECG). The device is typically used bedside.
