Excellent article about what a drowning victim actually looks like/experiences. My own experience as a lifeguard and training lifeguards bears this out.
Drowning Doesn't Look Like Drowning
Secondary Drowning:

Secondary drowning happens when a person has already been saved from drowning, but sometimes several hours later the lungs start filling up with fluid again. this is usually because the lining of the lungs have been severely irritated during the first drowning if a significant amount of water has gotten into the lungs, and the reaction to that creates fluid excretion that ends up inside the lung. especially when a person has drowned in salt water, the salt can draw more water out of the lung tissues. So, a drowned person can be revived, then feel OK for while afterwards, but then become extremely ill again afterwards and sometimes even die from the secondary drowning.
Therefore, even if the victim feels OK after the initial drowning experience, always take them to a hospital for observation.
Compare it to when you have a bad cold and the membranes inside your nose produce a lot of watery stuff (runny nose). A similar thing happens inside the lungs when they are irritated by the effects of the first drowning. Mainly salt water, and heavily chlorinated pool water will make this worse. Pure fresh water is not as bad (but fresh has other side effects as it gets absorbed in the blood stream and affects the chemical balance of the blood.
I never heard of this until I read the article in the New York Daily News. I believe this would get past the most seasoned rescue personnel. Bottom line. Take any drowning victim to a hospital for observation if you believe he/she fits the criteria above.
