Abstract
Described is a method and a system for detecting the arterial oxygen saturation of hemoglobin (also called blood oxygenation, SpO2 or SaO2 measuring), comprising a measuring device for performing a blood oxygenation measurement and a controller unit. The measuring device is controllable by the controller unit so that the blood oxygenation measurement can be performed non-continuously. In a first step the measuring device is powered on, in a second step the blood oxygenation measurement is performed, and in a third step the measuring device or parts thereof are powered down, whereby the three steps are repeatable periodically. This provides SpO2 measurement applicable in telemetric or handhold instruments. The system is preferably used in telemetric or handhold instruments.
