Perhaps the most important question would be, "How long would it take for a capable paramedic to respond to your 911 call?" Transport in a private vehicle might or might not be a good idea. The paramedic will be in communication with the ER, and will have expanded capabilities over even a well trained layperson. They can best utilize the "Golden Hour."

Would love to hear comment from some of the PMs on this forum...
