intermittent measurement of the arterial oxygen saturation of hemoglobin

摘要

Described is a method and a system (5) for detecting the arterial oxygen saturation of hemoglobin (also called blood oxygenation, SpO2 or SaO2 measuring), comprising a measuring device (10) for performing a blood oxygenation measurement and a controller unit (40). The measuring device (10) is controllable by the controller unit (40) so that the blood oxygenation measurement can be performed non-continuously. In a first step the measuring device (10) is powered on, in a second step the blood oxygenation measurement is performed, and in a third step the measuring device (10) or parts thereof are powered down, whereby the three steps are repeatable periodically. This provides SpO2 measurement applicable in telemetric or handhold instruments.
