The bite actually doesn't kill you, it just shuts down your nervous system so you can't breath.

People if given cpr immediately (kind of need someone to know it's what bit you) till it wears off / get on a ventilator will live.

I remember reading about someone who survived. They got but, and a team started doing cpr. The only issue was his eyes were open the entire time on a hot sunny day. So he was blind after the damage the hot sun did.

Blind as permanently blind?

[-] Wooki@lemmy.world 39 points 5 days ago

Correct, nothing can move, not your lungs, not your eye lids, nothing. So he went very blind from staring at the sun for 30mins straight while people did cpr until ambulance arrived

[-] 50MYT@aussie.zone 15 points 5 days ago

Yep.

They couldn't close their eyelids.

Better blind than dead.

Too bad no one had a shirt or something they could've covered their eyes with...

Hindsight is 20:20. It may seem obvious when you’re sitting here reading about it, but if my buddy was suddenly paralyzed I’d probably be too preoccupied with keeping his blood moving and oxygenated to have the extra processing power to think about whether his eyes needed to be closed.

Hindsight is 20:20

😂

Is it though?

What about the heart?

It would take a very large dose to affect the heart and even then it would just lead to a slower heart rate instead of stopping it. The heart does not need nerves to tell it to beat and it's action potential triggering is different than muscles and nerves. They'll be brain dead from being without oxygen before they're heart dead, similar to opioid overdoses.

Thus the CPR, I would imagine.

[-] abfarid@startrek.website 2 points 5 days ago

Does it just automatically restart beating after effects wear off?

[-] ggppjj@lemmy.world 3 points 5 days ago

I would personally imagine that you may need to be defibrillated at some point but otherwise probably yes? The toxins are causing the paralysis and people do survive it so I can only imagine that the heart takes back over after a certain amount of effort. Otherwise, I don't actually know.

[-] RedditRefugee69@lemmynsfw.com 9 points 5 days ago

Defibrillation is only useful if the problem is your heart is doing some kind of fibrillation.

If it's not beating at all, other methods like manual massage or chemical restarts (epinephrine) are the right move.

Gotcha. My CPR training was so long ago, and the only relevant information that really stuck with me was "the AED will directly instruct you if it thinks a shock is helpful based on what it detects", after that the specifics just kinda fell through my brain.
