Q: Is this item returnable if it doesn't work for me?

NO! Not at all, Amazon says it's hazardous therefore non-returnable. What a JOKE! They can ship it but can't take it back? BTW, these are nearly empty upon arrival, not a hint of liquid in the cans, 50 breaths in each can? For a one lung baby maybe.

Q: how much does each canister weigh?

Each canister weighs about 1.3 oz

Q: Is there a propellent? What is the other 1-2%?

We are the only company that uses Vacuum Crimping. The only thing inside the can is Pressurized Oxygen. Video shows how we do this.
