Classification: CPC A  G | IPC A  G

Claim 12:
13. A method of measuring a blood parameter, preferably related to the presence or concentration of oxygen in blood, comprising the steps of:
exciting a photosensitive element in contact with blood by a series of excitation pulses, blood circulating in an extracorporeal blood circuit,
dimming or terminating the excitation step between consecutive pulses of the series of excitation pulses,
detecting a plurality of light responses of the photosensitive element corresponding to the series of excitation pulses, the light responses providing respective luminescence decay curves,
analyzing the plurality of luminescence decay curves, said step providing to analyze each luminescence decay curve at a least two time windows,
detecting one or more light response analog information regarding the decay of the luminescence curve at each time window,
converting the light response analog information, detected during at least two time windows for each light response, into light response digital data,
processing said light response digital data and the actual temperature value of blood considering a plurality of data of previous measures of said blood parameter performed during previous training, and
determining, as a result of the processing step, at least one value of said blood parameter.
