Is emergency medical transport deductible?

yes

• Ambulance service and other travel costs to get medical care. If you used your own car, you can include what you spent for gas and oil to go to and from the place you received the care; or you can include 18 cents a mile for January 1 through June 30, and 22 cents a mile from July 1 through December 31. Add parking and tolls to the amount you claim under either method.

Yes, as a Medical Expense. 

That expense would be added to your other medical expenses, and reported on Schedule A if you Itemize Deductions.
