Sedate Your Kids While They Play
If your child won't sit still at the dentist, the doctor, or the kitchen table, you need the PediSedate Helmet. The device consisting of a colorful headset that connects to a game component or a portable CD player. After a snorkel attachment goes into the child's mouth, the helmet will monitor respiratory function and distribute nitrous oxide or anesthetic gas. The company website states, "The child comfortably becomes sedated while playing with a Nintendo Game Boy system or listening to music. This dramatically improves the hospital or dental experience for the child, parents and healthcare providers."
The kid died from respiratory obstruction due to a malformed lower jaw and pneumonia. The article you're linking to mentions that the NO2 did aggravate those factors, but it was hardly the cause. Also, the article is from 1926 and the death occurred in 1923... pneumonia was the 2nd leading cause of death in 1923 as well.
Oh god, that woman is John Romero!
