Problems solved by technology

So far, several public attempts have been made to normalize EFM interpretation, but biases are common, and interpretations remain highly subjective and rarely physiologically justified

Embodiment Construction

[0034] As required, detailed embodiments of the present invention are disclosed herein. It is to be understood, however, that the disclosed embodiments are merely illustrative of the invention, which may be embodied in various and alternative forms. The figures are not necessarily to scale and some features may be exaggerated or minimized to show details of particular components. Therefore, specific structural and functional details disclosed herein are not to be interpreted as limiting, but merely as a representative basis for teaching one skilled in the art to employ the present invention.

[0035] Referring now to the drawings, methods and apparatus for objectively determining and confirming fetal risk during labor are disclosed. The method most commonly includes the step of monitoring at least each of the following concurrent clinical parameters— (a) fetal heart rate, (b) baseline fetal heart rate variability, (c) fetal heart rate acceleration, (d) fetal heart rate Heart...

Abstract

Provided is a method for identifying the level of fetal risk during labor comprises monitoring at least each of the concurrent clinical parameters of (a) FHR, (b) baseline FHR variability, (c) FHR accelerations, (d) FHR decelerations, and (e) maternal uterine activity, to determine whether each parameter independently exhibits at least one non- reassuring characteristic, and indicating a present level of risk to the fetus corresponding to the number of the concurrent clinical parameters (a) through (e) that are simultaneously, independently non-reassuring. An apparatus for implementing the method comprises at least one computer operative to receive input signals indicative of at least FHR and maternal uterine activity in a patient. The computer is operative to determine from the FHR baseline FHR variability, FHR accelerations, and FHR decelerations, to determine when any one or more of the parameters (a) through (e) each exhibit at least one non-reassuring characteristic, and to determine a present level of risk to the fetus corresponding to the number of the parameters (a) through (e) that are simultaneously, independently non-reassuring. At least one output operatively connected to the at least one computer indicates the determined present level of risk to the fetus.

Description

[0001] Cross-references to related applications [0002] This application is related to and claims priority to US Patent Application Serial No. 12 / 345,090, filed December 29, 2008, the disclosure of which is hereby incorporated by reference in its entirety. technical field [0003] The present invention relates to a method and apparatus for confirming the current risk level of the fetus during childbirth by: monitoring a number of parameters related to the risk of the fetus, and comparing the number of those parameters simultaneously, independently non-reassuring Transformed into a corresponding indication of the level of risk to the fetus during delivery. Background technique [0004] It is well known that, when fetal reserve is reduced, any reduction in maternal cardiac output, maternal blood oxygenation, or maternal uterine blood flow, if labor is allowed to continue, will subsequently place the fetus in a fetal position. Significant risk of hypoxia and asphyxia (metabol...
