According to the World Health Organization (WHO), drowning is the process of experiencing respiratory impairment from submersion/immersion in liquid, which is accompanied by the inability to breathe and heartbeat.
Drowning, the WHO explains, can occur in any body of water - from bathtubs and pools to oceans and rivers. It's a global health concern. It's estimated that over 236,000 people die from drowning each year worldwide, according to the WHO's data.
Understanding Drowning Mechanics
Drowning is primarily an oxygen deprivation process rather than a water swallowed issue. When a person's mouth, nostrils, and/or pharynx (throat) become submerged, they instinctively try to breathe, taking water into their lung passages. This can cause frantic gasping, chest pain, and may ultimately lead to collapse.
Initially, the person may not display obvious signs of struggle, which often surprises bystanders. Even seasoned swimmers can get into trouble, so it's crucial to immediately respond if you suspect someone is drowning.
Instinctive Drowning Response
Any person who is drowning typically exhibits an Instinctive Drowning Response (IDR). authors Franko & Bishop, in their article in the American Red Cross First Aid and Safety Handbook, describe IDR as follows: "The individual's body becomes completely vertical with their mouth at the surface, providing minimal buoyancy due to(Action-basis=Emphasis=tone*strong*) the sculling and clawing movements produced by their elbows and upper body, which bear no resemblance to the familiar actions of a tired or frantic swimmer.
Controlling the sequence of events crucial for survival - getting the face out of the water to breathe - is unsuccessful due to a futile struggle for air, leading to unintentional body re-submergence.
Signs of Drowning in Adults and Children
Adult and child drownings can both clinically present in similar ways. However, the circumstances surrounding them may be different. An adult may find themselves in deep, cold water or have fallen through thin ice, whereas a child might be playing unsupervised around water or have slipped out of sight in a bathtub.
Common signs of drowning in both adults and children include:
- Head low in the water, mouth at water level
- Head tilted back with mouth open
- Eyes glassy and empty, unable to focus
- Eyes closed
- Not calling for help
- Trying to roll over on their back
- Appearance of being climbing an invisible ladder (this is a sign of hyperventilating)
Preventing Drowning Incidents
While swift action is crucial in suspected drowning events, preventing such incidents in the first place can save lives. Modifiable risk factors include access to safe water, swimming lessons, supervision, and legislation enforcing safety restrictions.
Efforts aimed at improving access to safety, teaching water safety skills, and ensuring adequate surveillance around water bodies, particularly for children, are key prevention strategies, as highlighted by studies in public health journals like Injury Prevention.
Swimming Lessons and Water Safety Education
Swimming lessons and water safety classes can drastically reduce drowning risks. They not only teach swimming skills but also educate about safety practices around water, signs of drowning, and what to do in emergency situations.
According to the Journal of the American Medical Association, swimming lessons can reduce the drowning risk for young and minority children by up to 88%. Moreover, ensuring these lessons are standardized and adhere to safety standards can maximize their efficacy.
Supervised Swimming and Safe Play Environments
Proper supervision is crucial around water. Drownings – even in shallow water – can happen quickly and quietly. It doesn't take much water for a child to drown. In fact, according to the American Academy of Pediatrics, toddlers can drown in as little as 2 inches of water.
Creating safer aquatic play environments – with barriers, fences, and alarms – can further deter drowning incidents. Additionally, having clear safety rules and ensuring everyone knows how to swim and perform CPR can save lives.
Finally, Promote drowning prevention awareness through educational campaigns, and support regulations that enforce water safety. By Pool safety barriers, life jackets, and adequate surveillance – everyone can play a role in reducing drowning risks and saving lives.
