The aim of the study is to assess the change of fetal heart rate in response to the amount of pressure exerted on the maternal abdomen. The amount of pressure will be quantified using an electronic pressure sensor (FSR 400- Round Force Sensor, Interlink).
Previous studies have shown a fetal cardiovascular effect to the pressure exerted on the maternal abdomen. Our null hypothesis is that there is a correlation between fetal heart rate changes and pressure exerted on the fetus through the maternal abdomen. Women at term pregnancy coming for a routine cardiotocography monitor, will undergo 5 minutes of quantified pressure on their abdomen, using the electronic pressure sensor. The amount of pressure will be recorded as well as the fetal heartbeat baseline and changes to the heart rate following the application of pressure.
Study Type
OBSERVATIONAL
Enrollment
100
The fetal cardiac response of either acceleration, deceleration or no change at all to the fetal heart- will be recorded and later on analyzed in reference to the amount of pressure applied from the 20th minute of CTG and for 5 minutes, using the FSR 400 sensor.
Meir Medical Center
Kefar Sava, Israel
Changes in fetal baseline heart rate, including accelerations and decelerations
pressure will be applied after the 20th minute of CTG monitoring and for a total of 5 minutes
Time frame: immediately after applying pressure to the maternal abdomen
