Field: Medical technology (Instruments)
Classification: CPC A | IPC A

Claim 5:
6. The method according to claim 5, wherein the transfer function uses the relation:

T(t)=−a1T(t−1)−a2T(t−2)− . . . −anaT(T(t−na)+b1P(t−1)+ . . . +bnbP(t−nb)  (1)

where T(t) and T(t−I) [I=1, 2 . . . na] are present and are previous output (radial tonometer) discrete measurements, respectively, and P(t−I) are previous input (aortic pressure) discrete measurements, a1, a2, ana and bnb are parameters of the model, and na and nb represent a number of previous input-output values used to describe the present output.
