Salt water and fresh water drown you in different ways

Factual Questions

"When salt water is inhaled the fluid in the lungs is hypertonic to the blood passing nearby, so plasma fluid fills the lungs (edema) and prevents gas exchange.

When fresh water is inhaled the fluid in the lungs is hypotonic to the blood; the fresh water moves into the blood stream, dilutes the plasma/electrolytes, and stops the heart."

I find this fascinating for some reason. But I was thinking it would be easier to recover from near-drowing in salt water. If you are able to cleat the lungs of that accumulated plasma you can begin gas exchange by forcing air into the lungs.

But in fresh water, the water has moved into the blood stream, and I don’t know how that can be remedied.

Of course there comes a point of no return in either scenario. But am I generally right here?

Either way a fluid enters your lungs and prevents gas exchange. That will cause death much faster than liquid exchange across the lungs.

Think about it: you have lungs full of saltwater but still need to add plasma to it to drown?

So what happens in merely brackish water that is blood neutral?

You develop gills and buy a catamaran. Very useful once global warming drowns the world.

That is true in cases where someone just sinks to the bottom of the ocean, but if someone has a near drowning experience and they inhale salt water, then the pulmonary edema becomes nearly as hazardous as the water inhaled. Remember that when you inhale salt water, salt can be deposited in the lungs which can cause edema long after the water has been expelled. This is all important stuff when you rescue someone who has been drowning and try to resuscitate him on shore. In general, it is far better to almost drown in fresh water than it is in salt water. But drowning in either makes you equally dead.
