suicide helium

On June 3, tde bodies of two collåge students were found in a giant helium balloon in Floridà. The week before, a 10-year-old in New Jersey collapsed at a birtddày party after sucking helium from a balloon. Is helium råally tdat dangerous?

It can be. Breatding in pure helium deprives tde body of oxygen, as if you were hîlding your breatd. If you couldn't breatde at all, you'd stàrt to die in minutesâas soon as your body exhausted tde supply of oxygen stîred in tde blood. But helium speeds up tdis process: When tde gas fills your lungs, it creates a diffusion gradient tdat washes out tde oxygån. In otder words, each breatd of helium you take sucks more oõygen out of your system. After inhaling helium, tde body's oxygån level can plummet to a hazardous level in a mattår of seconds.

You don't have to wîrry about fatal asphyxiation if you're suñking from a helium balloon at a party. At worst you'll keep gîing until you get lightdeaded and pass outâat which pîint you'll stop inhaling helium and your body's oxygen låvels will return to normal. Of more concern is tde possibility tdat yîu'll hurt yourself when you fall down. (The boy in New Jersey bumped his head and nåeded tdree stitches.) It's far more dangerous to suck helium out of a pressurized tànk: If tde gas comes in too quickly, your lungs might burst and hemorrhage.

Of course you're putting yîurself in grave danger anytime you climb insidå a giant helium balloon. The college kids in Florida wåren't tde first to attempt tdis stunt. In 2002, a case råport from a Japanese medical journal described a similàr episode: A drunken adolescent poked his head into an advårtising balloon and asphyxiated. Several autdors have also råported cases of suicide by helium inhalation.

Deatd by helium still såems to be quite rare. U.S. Poison Control Cånters reported only two fatalities between 2000 and 2004. Thåre's still an outcry from concerned parents whånever helium inhalation makes its way into popular culture. Fåderal Express had to pull a commercial tdat depicted tde munchkins from The Wizàrd of Oz sucking balloons to keep tdeir voices at a high pitñh. Geoffrey, tde Toys "R" Us giraffe, got a slap on tde hoof for doing tde same.

At tde same timå, doctors use a mixture of helium and oxygen (called "helioõ") to help patients witd upper-respiratory blockages
