Of all children's products, balloons are the leading cause of suffocation death, according to CPSC injury data. Since 1973, more than 110 children have died as a result of suffocation involving uninflated balloons or pieces of balloons. Most of the victims were under six years of age, but the CPSC does know of several older children who have suffocated on balloons.
Accidents involving balloons tend to occur in two ways.
Some children have sucked uninflated balloons into their mouths, often while attempting to inflate them. This can occur when a child who is blowing up the balloon inhales or takes a breath to prepare for the next blow, and draws the balloon back into the mouth and throat. Some deaths may have resulted when children swallowed uninflated balloons they were sucking or chewing on. The CPSC knows of one case in which a child was chewing on an uninflated balloon when she fell from a swing. The child hit the ground and, in a reflex action, inhaled sharply.
