Shallow Water Blackout

This is the raw footage I was shooting when I got hit with a blackout - no editing. My dive buddy recognized what had happened immediately, and saved my life. I had done this dive 100 times before, and I never felt any panic or contractions. I did not hyperventilate, and my surface interval was not overly short. SWB can happen at any time to any of us. Watch your buddy. Be smart. Dive safely.

...and I still have no idea why I hit the shutter when I blacked out. I wish I hadn't, and allowed the camera to keep rolling.

So it would be a pretty good suicide method then?

@bonchasilark Seems like a lot of work for suicide. Shallow water blackout is more likely to occur when you come up from depth. If you take water into your lungs, while conscious, it would be extremely painful - not a nice way to go. So, you'd need to train heavily and become a good freediver be able to kill yourself. But, once you were good at freediving, you would no longer want to kill yourself. :) So, NO, I would say this is NOT a good way to commit suicide.

i dont t get it dont u still breathe wile  unconcious?

[unirdna]

Not if the air passages in your nose is cut off from oxygen/air. It's the bodies reflex against drowning (letting water into the lungs). So, when you black out, you do not try to breath in... until someone removes your mask, and lets fresh air into your nasal airway.

if thats true how do people die from water black outs

[unirdna]

When you black out, you float face down in the water. If someone isn't there to remove your mask, and lift your head above water, you die.

Shalow water Blackout is! You dive deep using up your oxygen and building up CO2,

more then doubles when you resurface because the biggest pressure change is at surface in around 0-16 feet! than every 33 feet 1 bar!

Important for free diving is Hyperventilating does not increase o2 level in the blood, it just blocking the need of breathing! Take breakes between every dive minimum 3 minutes, and do not hyperventilate more than 3 times! Or do freedive classes, many people would be still alive...

Holy shit man! I hope it will never happen to you again. How did you feel while you were passed out? I heard from an US Special Forces Instructor that you'll see black than you'll hear a noise coming up to you and your awake.

@bonchasilark basically tricking their body into thinking they have more oxygen in their lungs than they do, this is because when u hyper ventilate they believe that doing so increases oxygen saturation, when in fact what they are doing is actually messing up the rhythm of normal breathing. If you do this you get shallow water blackout. You simply lose consciousness by hypoxia. You die end of story unless there is a trained lifeguard who spots you...!!!!

@bonchasilark Unless you are really really lucky, you drown. I have blacked out three times. All three times my buddy was right next to me and stopped me from sinking. Without their intervention, I would have certainly died.

[bonchasilark]

Hey, say if you pass out and no ones there, do you drown or do you gain conscious again?
