Apparatus for Continuous Monitoring of the Fetal Heart Rate *
APPARATUS FOR CONTINUOUS MONITORING OF THE FETAL HEART RATE.* By Edward H. Hon, Department of Obstetrics and Gynecology, Yale University School of Medicine. During the past four years continuous monitoring of fetal heart rate during labor and delivery has permitted the accumulation of accurate, permanent records which may be of value for the assessment of fetal heart rate as an index of fetal e...
متن کاملThe future of fetal heart rate monitoring.
Medical technology is developing at an accelerated rate. Advances and refinement in techniques of electronic fetal heart rate (FHR) monitoring are continually being designed and tested. Many of these show real promise for the future. Never-theless, for the next several years there are two major considerations. First, a more universal application of FHR monitoring i.e., to the "normal" patient ä...
متن کاملA portable recorder for long-term fetal heart rate monitoring
A PIC17C44 microcontroller development board and a real-time algorithm were developed with the capability of monitoring the fetal heart rate (FHR) as well as recording both the FHR and maternal heart rate for long-term. This paper describes the development of the microcontroller board and implementation of a real-time algorithm which were used to develop the portable recorder. Two set-up were d...
متن کاملIntrapartum fetal heart rate monitoring. VIII. Atypical variable decelerations.
A total of 1,996 fetal heart rate (FHR) tracings were analyzed to assess the prognostic significance of variable decelerations. Nineteen percent (186 cases) of 988 tracings with variable decelerations in the last 30 minutes of monitored labor exhibited signs of atypia listed in order of frequency: (1) loss of initial acceleration, (2) slow return to the baseline FHR, (3) loss of secondary accel...
متن کاملSpontaneous prolonged contractions during antenatal fetal heart rate monitoring.
Uterine contractions of more than 2 minutes' duration occurred spontaneously in 1.4% of 6,399 antenatal fetal heart rate (FHR) recordings. All recordings were made in the Department of Obstetrics and Gynaecology at Tygerberg Hospital. The patients with spontaneous prolonged contractions (SPC) were compared with a randomly selected control group. Patients who had an SPC during antenatal FHR reco...
