Fetus risk class includes at least monitoring each parallel clinical parameter (one) FHR during a kind of identification childbirth, b) baseline FHR variability, (c) FHR accelerates, (d) FHR slows down, (5) maternal uterine activity determines whether that each parameter is independently presented at least one non-reliable feature, and to the corresponding concurrent clinical parameter (one) of the current quantity of fetus risk by (multiple) simultaneously with one another, it is individually non-reliable. For implementing the computer of this method, FHR and the movable patient of maternal uterine are indicated to receive an at least input signal at least. Computer is performed from the data and determines baseline FHR FHR variabilities, FHR accelerates, FHR slows down, to determine when any one or more parameters (one) are by (multiple) each at least one non-reliable characteristic of presentations, with determining current risk to the corresponding parameter of fetus quantity (one) by (multiple) simultaneously with one another, individually it is non-reliably. Airtight petite persons output is operatively coupled to current risk determined by the instruction of at least one computer to fetus.
