Female diving. Diving and pregnancy
Diving pregnancy is the subject of much discussion and research. We advise you to refrain from diving during this time. Since adverse effects can be both for the mother and the fetus.
Possible consequences for mother
1. The second and third months of pregnancy are often associated with nausea and vomiting, which underwater can create a risk of drowning.
Starting from the 2nd trimester of pregnancy, exposure to all kinds of barotraumas becomes especially topical. Blowing out becomes problematic due to swelling of the mucosa of the upper respiratory tract.
As the fetus grows and its pressure on the diaphragm increases, breathing difficulties begin to progress, and this leads to an increased risk of lung barotrauma and hypoxia.
Significant deviations in the circulating regimen and blood structure increase the risk of DB.
The flow of amniotic fluid, which occurs in the last months of gestation, creates a risk of penetration of infected bacteria into the body.
In the third trimester of pregnancy, a woman has an incomparably reduced reaction to external circumstances, as a result of which she is not able to take decisive responsible actions.
In the last 3 months of pregnancy, mobility is lost and fatigue increases, due to which scuba diving is unacceptable.
Effect on the child
When floating to the surface, even a tiny bubble of gas can have a terrible reaction to the embryo. When vesicles appear in the vein of an adult, they are filtered and removed in the lungs. The lungs of the embryo are not yet functioning, and the circulatory system includes only one circle of the circulatory system, passing through the interatrial septum. In view of this, any vesicle formed in the veins, at the time of the mother’s ascent, enters the arterial system and continues to grow, resulting in a fatal embolism of the child. Hypoxia, which occurs when salt water is inhaled or in a state close to drowning, carries a mortal danger to the embryo.
There is also a double danger to the embryo when treating the mother with pure oxygen or increasing the partial oxygen pressure in the pressure chamber or under water. The first is the likelihood of blindness due to an increased sensitivity of the eyes to oxygen. The second is the possible risk of “opening” a small circle of the circulatory system and untimely closure of the atrial valve. During measurements made by the Doppler counter, bubbles were detected in the blood of pregnant women even with shallow dives without decompression. This suggests the conclusion that the high tendency of women to DB during pregnancy increases. American doctors who tracked the fate of more than one hundred submariners who were immersed in water during pregnancy, a high percentage of miscarriages, early births and children with unnaturally low weight. Between the famous Japanese divers Ama, this figure reaches 44%.
To summarize: immersions affect the unborn child adversely. It’s a paradox, but among pregnant scuba divers, the leading place belongs to the Americans – the same emancipated Americans leading the campaign against abortion. In their opinion, abortion is a murder. In this case, the victim is an embryo that is unable to respond. But, the painful thirst for equality with submariners men makes them bravely dive, while forgetting to consult with their unborn child.
What to do if a woman dives while pregnant?
Although diving during pregnancy is not recommended, it may happen that a woman dives without knowing that she is pregnant (i.e. at the very beginning of the term). In principle, this should not be a cause for serious concern, and short-term exposure to the fetus of high pressure does not require an artificial termination of pregnancy. However, if during the dive there were problems that led to any damage, you should discuss everything that happened with the gynecologist and, if necessary, with a specialist in high pressure medicine.
How long after the birth of a child can I resume diving?
This decision should be made by the woman herself and her gynecologist. It all depends on how quickly the woman recovered after giving birth, how they proceeded, whether a cesarean section was done, whether any complications arose, etc. The only thing that can be recommended is to resume diving classes only after full restoration of health and obtaining permission from doctors for large physical activities.
