2. Things to avoid when drowning
Most victims of asphyxiation when taken to the emergency department of hospitals do not receive first aid or improper first aid resulting in death or brain sequelae due to lack of oxygen. Incorrect first aid methods include:
– Spending a lot of time on the water shock: the upside down movement is unnecessary and should not be done because often the amount of water entering the lungs is very little, not the lungs filled with water like people think. This very small amount of water is expelled when the victim breathes again. In addition, flushing also slows down the emergency time and increases the risk of choking.
– Roller roll: for children to lie on their stomach on a pot to let the burning straw inside roll back and forth in order to “drain the water” in the child’s body. This method is ineffective, and also causes burns to the child.
– The victims of cardiac arrest apnea are not given first aid to suffocate and press the heart at the place where the accident occurred or while transporting the victim to the medical facility. This causes the brain and organs to be chronically deprived of oxygen, brain cell death leads to death and severe brain sequelae. So, it is best to have ambulance as soon as possible to get the victim’s head out of the water before bringing it ashore.
3. The following factors increase the risk of asphyxiation
- Can’t swim or appreciate his swimming ability.
- Risky behaviors such as bathing in the river, playing on the banks of lakes, …
- Lack of adult supervision.
- Hypothermia leads to rapid exhaustion and inability to swim.
- No primary arrhythmia was detected.
- In older children it can be caused by drinking alcohol, drug use …
- Injury, cerebral vascular accident , myocardial infarction .
- Increasing ventilation before jumping into water reduces PaCO2, while PaO2 decreases to 30-40 mmHg due to consumption. Because the PaCO2 is reduced, it does not stimulate respiration. This causes cerebral hypoxia, convulsions, loss of consciousness leading to drowning.
