The Core

Can we compare notes on things that might be useful when getting quick/any help from a hospital or ambulance is not an option ?
I hope I'm just exaggerating but it seems possible that may be a (temporary) reality at some point.

My wife has severe astma and we live far away from any hospital so just buying some time for ourselves (or neighbours and friends in the area) may be important.
No medical training worth mentioning so I am counting on the internet to stay available and teach me things when I need it.

I bought a couple of manual resuscitators. I figure these things can buy some time when someone is developing breathing problems. I'll have to study on how to use it properly as they can be dangerous as well.

We already had some pure oxygen bottles in stock (Single use). I know from experience they can buy time and are a relief for somebody (astmatic) grasping for air for an extended period of time. Example: https://www.amazon.co.uk/Gox-Oxygen-Liters-Inhalation-Caps/dp/B001EHM5JC

Look for larger sizes of the Sure Seal bandages, too. They have a pad of hydrogel that swells to apply pressure directly to the wound. The adhesive is very, very strong and with withstand washing & showers.  These are 'field dressing' quality and will stop bleeding when little else will.  I know that some commercial emergency kits have Sure Seals for bullet wounds.

There is also a powder that emergency technicians use to clot a big wound, but I don't have that.

Yes, thanks. They sell for crazy prices now (if you don't have a kindle) so I searched for 'title + PDF'
Found all three with three clicks.
