Is the fetal movement a shake of hypoxia?

Fetal movement is not hypoxia, fetal movement how to move is OK, as long as the fetus in the activity can be considered normal, some are big roll, some limbs or arms, legs stretch out movement, some are slight small movement, even some like hiccups, are fetal movement way, each fetal movement way is different. But the fetus a shake, does not represent hypoxia, hypoxia performance for fetal movement decreased, such as less than three times an hour fetal movement, or abnormal fetal movement for an hour without stopping, back and forth movement, all indicate that the fetus has intrauterine hypoxia.
