Babies do not “breathe” in the womb. Infants, on the other hand, get oxygen for their growing organs from their mother’s breathing. The placenta of the mother provides oxygen to the baby. The placenta sends oxygenated blood to the umbilical cord, which subsequently travels directly to the infant. Beginning in the first trimester, pregnant women must ensure that their unborn children get enough oxygen. The first breath of a newborn, on the other hand, occurs shortly after delivery. The initial few breaths cause substantial circulatory rearrangement, nearly filling the lungs to capacity while simultaneously lowering lung pressure and resistance to blood flow significantly.
The placenta and the umbilical cord are two organs that enable a developing baby to get all of the nutrition it need from its mother. The umbilical cord, which links the infant’s abdomen to the placenta, transports oxygen, nourishment, antibodies, water and other elements to the baby from the mother’s bloodstream. The mother’s diet must be well-balanced, and she must avoid toxins and alcohol, both of which may be harmful to the kid.
In most pregnancies, lung development is completed around week 35-36. There is still no way for the unborn child to breathe until after delivery, even with fully formed lungs. Baby’s lungs are filled with amniotic fluid, which surrounds and surrounds them throughout development. When a baby is about 10 and 12 weeks old, it begins to take “practice” breaths. However, these breaths do not deliver any oxygen to the fetus and instead just replenish the lungs’ amniotic fluid reservoirs.
What happens when a kid takes its first breath?
The body of a newborn undergoes changes to adapt to life outside the womb. During labour, the contractions press and push the baby out of the delivery canal. Constant contractions force amniotic fluid from the baby’s lungs, making it ready to breathe on its own. While the baby is being born, it’s possible that it will be exposed to some oxygen. However, as long as the baby is still attached to its mother through the umbilical cord and the placenta, it is not necessary for the infant to attempt to breathe just yet.
The baby’s first breath will be a sharp inhalation, which will occur within a few seconds after delivery. The doctor will clip the umbilical cord around thirty seconds after the baby is born, physically separating it from its mother for the first time. After birth, this transformation occurs in a series of quick shifts. When a newborn is delivered, the cells in the lungs that secrete fluid begin to absorb it, freeing up space for the incoming oxygen. As soon as the lungs are empty, they fill with air. Though their lungs are now able to meet all of their oxygen requirements, babies’ respiratory systems still have eight to ten years of development ahead of them.
Once the newborn inhales for the first time, many changes occur in the infant’s lungs and circulatory system
- The lungs expand and start functioning on their own, bringing oxygen into the circulation and exhaling CO2.
- Increased oxygen in the lungs reduces pulmonary blood flow resistance.
- The respiratory system drains or absorbs fluid.
- The baby’s blood flow resistance rises.
Neonatologist and Cincinnati Children’s Hospital Director Dr. Jae Kim explains that when a newbaby is born, the right side of the heart is dominant. This is due to the fact that it has been supplying the whole body with oxygenated blood through the two temporary shunts. The vascular system, on the other hand, changes after birth. After birth the left ventricle takes over the charge of transporting blood throughout the body, while the right ventricle is now in charge of delivering oxygen-poor blood to the lungs.
What should a pregnant woman avoid?
The baby’s lungs may not be completely developed if he or she is born prematurely. RDS (respiratory distress syndrome) is a disorder that may occur as a consequence of the infection. Preventing an early delivery may be as simple as paying close attention to your food and lifestyle choices while pregnant.
In accordance with the advice of the American Pregnancy Association, pregnant women should avoid the followings:-
- Smoking and Cigarettes
- Uncooked seafood & High mercury fish
- Raw or undercooked meat and eggs
- Raw or semi ripe papaya & Pineapple
- Raw sprouts & Pre-packaged salads
- Too much caffeine
- Junk foods
- Unpasteurized dairy products and unpasteurized juices
- Drinks with artificial sweeteners, like diet soda
- Processed meats such as hot dogs and deli meats
- Mould-ripened soft cheese
- Liver products & Supplements containing vitamin A
Pregnancy doesn’t require major lifestyle changes for most women; they just have to make a few small adjustments. A woman’s and her unborn child’s health and well-being come first during pregnancy, so it’s better to avoid certain foods and activities that may be harmful.
