The other day I was writing a story on aquatics safety tips in a facility, when the guy I was interviewing said something along the lines of, “Yeah, and we try to prevent shallow water blackout, since it’s a huge concern for the industry right now.”
I immediately had to Google “shallow water blackout” after getting off that phone call. I kept trying to guess what it was, but my definition was vastly different than the definition from the one on shallowwaterblackoutprevention.org, which states:
“Shallow Water Blackout is an underwater ‘faint’ due to a lack of oxygen to the brain brought on by holding your breath for long periods of time. Without immediate rescue, the swimmer quickly drowns; or more formally:
“Shallow Water Blackout results from hypoxia — low oxygen — to the brain. What triggers one to breathe in elevation of carbon dioxide, not low oxygen. One basically ‘blacks out’ or faints in the water. For some, their lungs will take on water leading to drowning. Others simply suffocate or die of other causes brought on by the breath-holding.
“Death can be a result of the prolonged breath-holding, even if not from so called ‘Shallow Water Blackout.’ Breath-holding may stimulate genetic triggers leading to various causes of death.”
It can occur in an olympic pool or the bath tub. It’s caused by breath-holding, regardless of where it occurs.
So, my first assumption: it probably happens to amateur swimmers and pool-goers, right?
Sure, it can. But, it’s most common among physically fit swimmers, spear fishermen and free drivers. While it has been a worrisome trend in Australia for a while — due to the coast and snorkeling adventures — it may be a worry you’ve never heard about. Many know it as a silent killer. In fact, it occurs in only two minutes, opposed to regular drowning which takes six to eight minutes.
25-year-old Gene “Whitner” Milner was interested in spear fishing and began to practice his breath-holding. But on April 17, 2011, Whitner died from shallow water blackout in his family’s swimming pool.
The website, shallowwaterblackoutprevention.org went live in June 2011 following his death. It hopes to shed light on shallow water blackout and help prevent these deaths that the website refers to as “completely preventable.”
Here the story from the website:
“The day Whitner died he was full of joy and happiness. He had spent the day at the Atlanta Steeplechase with his friends and little sister, Scottie. Following the Steeplechase, a group of his friends and his sister’s friends came back to his parent’s house to cool off and enjoy the pool and hot tub. The group were swimming laps, racing each other and competing to see who could hold their breath the longest.
“The last anyone remembers seeing Whitner is when friends were getting out of the pool around 10:30 to 11 p.m. that evening. The pool lights were not on and his friends were coming and going. Whitner likely tried to hold his breath one last time, unnoticed by those around the pool. He experienced shallow water blackout and passed out in the water without any forewarning sinking directly to the bottom of the pool. His friends thought that he had gone inside to call his girlfriend, Laura Dobrosky, who was out of town.
“Several people were by the pool during the day collecting towels and personal items. No one ever saw him at the bottom of the pool, showing how difficult it can be to detect a drowning. He was not found until the following Sunday evening around 7:45 p.m. by his mother because she went out to turn off lights by the pool.”
Share the information you learned with others, both in your facility and outside of. Inform your lifeguards to try and monitor those who are training for swim meets by making sure they come up for a proper breath. Never allow breath-holding games. Inform pool goers to breathe when they have the urge.
