How long does drowning take

How do you spot someone in trouble? And how proficient should Australian children be in the water? Contrary to the Hollywood stereotype, nobody in any of the 23 videos reviewed by international experts waved or called for help. The videos had been sourced from closed-circuit cameras and from people who had realised they had filmed a drowning only after the event.

That backs up what lifesavers see on beaches and in pools and rivers. In November , a video went viral that captured the recovery of a year-old Chinese student who fell in a river. She made no noise, and floated face down until she was rescued by year-old Stephen Ellison, a British diplomat and consul-general.

In half the videos studied by experts, bystanders swam, walked or waded near the person in trouble. In the video of the boy, he is seen trying to reach the edge of the pool.

He makes it momentarily, only to drop in exhaustion next to adults chatting in the shallows. Face down beneath the water, his limp and unconscious body is carried by the movement of the water across the pool. He comes to rest next to a woman who raises the alarm. They are not playing; they are fighting for their lives. Other videos show people swimming laps over the top of people who have sunk after only a few strokes, and children whose flotation devices have capsized, trapping the child upside down beneath the water in both a pool and a large bath.

In the case of the boy in the video, his mother had left the pool to have a sauna with a friend, presuming he would be safe surrounded by adults and children. Peden studied the drowning deaths of children under five in which coroners ruled distraction was a factor. A child can die in the time it takes to hang out a load of washing or stir food on the stove. Housework inside the home — ironing and cooking — were contributing causes in about deaths about 28 per cent. Hanging out washing and other outdoor jobs and chores contributed to 13 per cent, and talking, socialising and playing with mobile phones about 21 per cent, found a paper by the University of NSW, James Cook University and Royal Life Saving Society Australia.

Peden says this provides an excellent reason to ignore the chores and play with your kids instead. Until the advent of mobile phone and surveillance cameras, there was only anecdotal evidence from survivors of non-fatal drownings about what happened and how they reacted.

But the videos of people drowning found 19 were rescued before they became unconscious and five were unconscious. Baker says the videos show that people who are trained to respond — lifesavers and lifeguards — are able to spot someone in trouble much faster than untrained bystanders.

In more than half of the videos, bystanders failed to recognise any signs at all. Baker says when weak swimmers begin to tire, they usually have trouble with any over-arm action. This is followed by changing to underwater arm action and then they are more upright in the water and are looking about for the closest point of safety or exit. He says they tend to lose any capacity to propel themselves forward. They often look like they are attempting to climb an underwater ladder or pushing their arms down behind them.

Most swimmers don't have the experience or skills to know to float and raise an arm. It sounds obvious, but watch for people whose faces drop below the water and don't surface fully to take a breath. When someone falls into water, they involuntarily hold their breath.

That causes their pulse rate and blood pressure to rise until they reach "break point," says Pearn, who is also the national medical adviser to the Royal Life Saving Society Australia.

There comes a time, though, when everyone has to take a breath and you can't get your head above the water, says Pearn. Think of what it is like to have a drop of water go down the wrong way, he says. In a drowning situation, water rushes into the lungs, causing the person to become unconscious. It takes an average of two minutes for someone drowning to become unconscious.

Would holding your breath delay this response? It may but even if you could, you shouldn't. Most people can hold their breath for only 30 to 60 seconds. Female Japanese divers can last two minutes — long enough to retrieve pearls. To learn more about Healthwise, visit Healthwise.

Topic Overview What is near-drowning? Near-drowning is a common but out-of-date phrase for surviving a drowning event. Going without oxygen has a rapid effect on the body.

Within 3 minutes underwater, most people lose consciousness. Within 5 minutes underwater, the brain's oxygen supply begins to drop. A lack of oxygen can cause brain damage.

What happens after a person survives a drowning? Right after a drowning, a person may: Be unconscious, unable to breathe, or without a heartbeat. Gasp for air, cough up pink froth, vomit, or breathe rapidly. Seem to be fine. When to call your doctor Call or other emergency services immediately if a drowning victim has: Lost consciousness. Stopped breathing.

No heartbeat. Most people who die by drowning are children. Drowning is a form of death by suffocation. Death occurs after the lungs take in water. This water intake then interferes with breathing. The lungs become heavy, and oxygen stops being delivered to the heart. Without the supply of oxygen, the body shuts down. The average person can hold their breath for around 30 seconds. For children, the length is even shorter. If a person is submerged after breathing in water for 4 to 6 minutes without resuscitation, it will result in brain damage and eventually death by drowning.

Every year, people drown in bathtubs, shallow lakes, and even small puddles. Some studies indicate that a person can drown in 1 milliliter of fluid for every kilogram they weigh. So, a person weighing around pounds A person can drown on dry land hours after inhaling water in a near-drowning incident.

Dry drowning , which refers to drowning that takes place less than an hour after someone inhales water, can also occur. However, the medical community is trying to distance itself from the use of this confusing term. If you or your child has inhaled a significant amount of water in a near-drowning incident, seek emergency care as soon as possible, even if things seem fine. Drowning happens very quickly, but it does take place in stages.

The stages can take between 10 and 12 minutes before death occurs. If a child is drowning, it may happen much more quickly. Children between the ages of 5 and 14, as well as adolescents and adults over 65, are at a higher risk for drowning. Children under 5 years old face an extremely significant risk of drowning.
