The person should pass out in 6 - 20 seconds. Depending on the person, irreversable brain damage will begin somewhere around 4 to 6 minutes. At 7 minutes, the brain will be dead but the drowning person missed it all as they passed out at 6 - 20 seconds.
Secondary Drowning: What It Is. Secondary drowning, also known as delayed drowning, is extremely rare but can be fatal if you overlook the symptoms. Anytime a liquid (like water, after a near-drowning experience) gets into the lungs, it can cause irritation. The body sometimes then sends fluids from other areas to the lungs in hopes of helping out. But instead of helping, the fluids leave little to no room for breathing, which can cause cardiac arrest or death. Secondary drowning can happen minutes or up to three days after the water first got into the lungs.
