Fetal monitoring of fetal heartbeat is very stable without acceleration indicates that the fetus may be in a sleeping state, fetal distress, umbilical cord compression and other conditions. 1. Fetus is in sleeping state: when doing fetal monitoring fetal heartbeat, the fetal heartbeat will accelerate after fetal movement, if the fetal heartbeat is very smooth without acceleration, it is likely that the fetus is in sleeping state, at this time, you can gently push the abdomen to wake up the fetus, and then do fetal monitoring fetal heartbeat. 2. Fetal distress: this may be the phenomenon of intrauterine oxygen deprivation, the fetus does not get enough oxygen, fetal movement is reduced, and in severe cases, it may cause fetal death. 3. Umbilical cord compression: Umbilical cord compression will affect the fetal activity, which will also lead to fetal hypoxia, and then show a steady fetal heartbeat without acceleration. If the fetal heart rate is stable without acceleration, it is recommended to repeat the examination several times. If there is no improvement, it suggests that the fetus is suffering from functional hypoxia, and it is recommended to carry out further treatment under the guidance of the doctor.
