Good kit!
To anyone that doesn't have any sort of training on this stuff I recommend trying to find a "Stop The Bleed" seminar in your area if you're in the US. It will cover tourniquet and pressure bandage use. I don't believe they get into airway problems or treating a tension pneumothorax at the classes.
Thanks! Yes, the hope is that the person qualified will be there, and then you'll have the supplies they need.
