Let's have fun with this but keep it as realistic as possible. Feel free to ask for any medication, treatement, or assessment tool you want, with the caveat that 1) you need to actually know how to use/do/administer it without checking Google, and 2) it's routinely carried on a 911 ambulance (though there'll be exceptions for that).
You are working on a primary 911 ambulance with a partner of the same skill level as you. Other than a helicopter there is no intercept with a higher level of care available. You are authorized by your medical control to perform any intervention/give any med that you feel is appropriate (as long as you follow the 2 rules above). You are currently working in an area that goes from urban to very rural, and are currently 60 minutes away from the nearest hospital by ground. A medic/RN helicopter with blood products and a few more advanced interventions/meds is available and will decrease your transport time by 20 minutes but will take 15 minutes to reach you. The first responders are minimally trained to the EMT level and there are as many available as you want. There is a Level 1 Trauma Center/Academic Hospital 75 minutes away, Level 3 Trauma Center/Stroke Center 70 minutes away, and a Level 3 Trauma Center/Community Hospital 60 minutes away. All have cath labs with interventional cardiologists, fully staffed ICU's, and are capable of at least general emergency surgery.
You are dispatched for an unconscious female with the local fire department and arrive on scene as the same time as an engine company with 3 FF/EMT's. The house is generally rundown and unkempt with no apparent danger. You are met by an unhurried adult male who tell's you that "my girl isn't feeling good and I can't wake her up." He leads you down a long narrow hall filled with junk to a back bedroom. Upon entering you see a adult (early 50's by appearance) female laying in bed not moving.
Go.
