Question

At the time of delivery of baby which moment of time consider as a birth time

Answer 1

When the female dialates to about 10 cm active labor begins. During a normal healthy birth the fetal head is facing downwards helping the cervix to flatten and dialate. Birth feet first (breech) is generally avoided due to possible delivery complications, and only about 3-4% of births end up being breech . Women are reccomended to perform certain yoga postures to insure the head emerges first.

While in the womb, the fetus does not breathe or digest, the placenta (aparā) does all this for the fetus. Carbon dioxide and waste products from the fetus are sent back through the umbilical cord and placenta to the mother’s circulation to be eliminated. The fetal lungs are collapsed and are not used for breathing since all oxygen and nutrition is supplied through the umbilical cord. The fetal heart is pumping blood through the body but only using two chambers, this ‘fetal circulation’ changes at birth. With the first few breaths, the collapsed lungs expand into air filled sacs. This change of pressure at birth allows blood to flow into the lungs activating all four chambers of the heart to begin to work.
