Introduction
At 22 weeks of gestation, fetal movements are generally clearly felt. Normal fetal movement occurs about 3 to 5 times per hour. If fetal movements suddenly increase or their intensity rises by 50% compared to the previous day, or if movements suddenly decrease, these changes may be related to fetal hypoxia. The normal fetal heart rate ranges between 110 and 160 beats per minute. Fetal hypoxia in utero can cause the fetal heart rate to become either abnormally fast or slow.
Under normal circumstances, the main symptoms of fetal hypoxia at 22 weeks gestation are changes in fetal movement and fetal heart rate. Close monitoring of fetal movements and heart rate is essential during pregnancy. If any abnormalities occur, prompt medical evaluation and treatment are necessary.
1. Fetal Movement
At 22 weeks of pregnancy, fetal movements are usually clearly noticeable. Normal fetal activity ranges from 3 to 5 movements per hour. A sudden increase in movements—specifically, an increase in intensity by 50% compared to the previous day—or a noticeable decrease in movements may indicate fetal hypoxia.
2. Fetal Heart Rate
The normal fetal heart rate ranges between 110 and 160 beats per minute. Intrauterine hypoxia can cause the fetal heart rate to become either abnormally fast or slow.
Fetal hypoxia poses significant risks. If abnormal fetal movements or heart rate are detected, immediate hospitalization for oxygen therapy is required to prevent harm to the fetus.
