Apparatus and method for signaling fetal distress and uterine contraction monitor for use therein

摘要

An alert system continuously monitors the heartbeat rate of a fetus and pressure in the maternal uterus and from this information measures parameters indicative of the condition of the fetus including heart rate, heart rate variability, heart rate deceleration, and uterine pressure, both steady state and peak. The measured parameters are compared with corresponding outer limits of acceptability and when those limits are exceeded the system alerts, sounding an audio alarm and actuating an appropriate indicator lamp which identifies the condition parameter that has transcended its assigned tolerance for more than a permissible time period.
