We bought a few cans for an elderly relative that has a compromised respiratory system. They have a medical oxygen bottle, but if it runs out or their cannula stops working for some reason we wanted them to have another option besides asphyxiation. There are not many minutes of oxygen in one of those cans, but if you’ve got nothing even a few minutes is a gift.
They’re sold at the checkout at Dick’s sporting goods. Pretty sure some woo woo people are picking up on them.
