Some other points I will address here from my perspective and experience...
I would not advise the use of a tourniquet unless it is the absolute last/only resort. They have not been used in our medical response protocol for many years now. They are likely to cause far more damage than good, and may lead to the loss of a limb. In cases of severed limbs and severe bleeding, stop the bleeding with whatever you have. Kotex are great, I carry many. If the bleeding does not stop, add more bandages. If it still does not stop, add more bandages. We do not use the gel blood coagulants on the MHSP for several reasons, but we train with it and it may help in severe bleeding situations. I would advise that you make your own first aid packs. I have several, and if anyone wants to know what I carry and why, I can list them here.
If you live in the PNW I would advise that you get LifeFlight or similar air rescue insurance. It is about $60 a year and will cover all costs of an air lift rescue for you and your family in all or parts of the states of OR, WA, ID, MT, NV, WY and CA. A typical Lifeflight rescue from Mt Hood to any of the hospitals in Portland, OR will cost you at least $30,000, and it is NOT covered by 90% of medical insurance plans, including Obamacare. In cases where life or limb is in peril, I call LifeFlight, regardless. Its protocol. Here is the LifeFlight Network web page:

As for law suits from rendering first aid, it completely depends on the state (and country) that you are in. In Oregon there are strong Good Sam laws and we first responders are protected from legal suits for rendering first aid, but only as non-paid volunteers and only when we follow protocol. Also that still does not stop people from filing lawsuits. Sometimes the first thing out of people's mouths when they have been rescued or helped is that they are going to sue! We always ask people if they want to be helped, and if they decline, we ask that they sign a waiver. If they are unable to respond, we must assume that they would want first aid.
CPR varies every time I renew my card. I have a Medical 2 person CPR card, which uses several methods of CPR, including the use of a defibulator. My latest CPR course advised more rapid chest compressions than previously, and gives a lower priority to rescue breaths. It always changes. Triage protocol also varies every time I take training in it. Triage does not always mean a mass casualty incident. It can be a tree falling incident with 2 guys and only one responder. You then have to decide what to do in what order. I have done a lot of triage scenarios, (some real ones) and every time I feel like I have failed miserably. You always miss and overlook something, and you simply cannot herd cats.
