Manufacturers : Safety and surveillance electronics : Fetal monitors
Fetal monitors are employed for monitoring both maternal and fetal vital signs prior to, during and after delivery. These vital signs typically include fetal heart rate measured by ultrasound, maternal and fetal ECG's and pulse oximetry; maternal blood pressure and uterine activity. It is conventional to ascertain the status and health of a human fetus by ultrasound. Typically a pregnant female may undergo 1 to 4 ultrasound examinations during her pregnancy. Electrical signals associated with the motions of the heart can be directly derived through electrodes connected to a patient and an electrocardiograph instrument to produce a display of an electrocardiographic, ecg, signal indicative of the heart motions. The circuit controls a chart recorder and/or other data presenting apparatus at which the fetal heart activity may be monitored by attending medical personnel. The heartbeat of a normal fetus has associated with it a frequency which varies between statistically acceptable limits. Variations in heart beat frequency patterns and/or deviations in such patterns from a norm can be correlated with occurrences of fetal distress. In gynecology and obstetrics, two medical parameters are important to assess the condition of the fetus. These two parameters are the fetal beat-to-beat heart rate and uterus (or labor) activity. Monitors measuring and recording both parameters are called fetal monitors or cardiotocographs (CTG monitors). Maternal blood pressure is typically monitored using a conventional pressure measuring system. Such blood pressure measurements may be initiated manually or automatically on a periodic basis.
