Can you believe that the child can get out of the water, and die from drowning hours later?! Yet, this is entirely possible. 4000 people die from dry drowning each year, 1400 whom are kids. What IS dry drowning?

Dry drowning is basically drowning without water. With dry drowning, you are not drowning from an immediate immersion in water; it is more of a delayed effect of a small amount of water in the lungs. This can cause result in laryngospasms, which minimize the amount of water aspirated into the lungs. Respiratory arrest may follow, leading to an inadequate supply of oxygen in the blood, cardiac arrest, and eventually brain death.

Are there any signs of dry drowning?

Yes, there are some signs that a person may have a dry-drowning episode. They include persistent coughing, shortness of breath, or pain in chest. All of those things are signals that something could be wrong. If someone comes out of the water and coughs for a minute, then calms down -- that is much different than if the child keeps coughing or complaining of pain. Like the child involved in the incident in South Carolina, a change in mental status and/or lethargy may also indicate that something is wrong.

So what do you do? Call a doctor. This is not something that a parent can do at home and the results can be lethal.

Who is at risk?It appears that kids who are first time swimmers, or simply can't swim, or have asthma are in greatest risk to the dry drowning.
