I'm an EMT in NY State. Here's what we do for shock (hypoperfusion):
1. Give oxygen, preferably 10-15 L/minute via non-rebreather mask, or by bag-valve if necessary.
2. Keep the patient warm (put a blanket over them)
3. Have them lie down supine (face up) with legs elevated (exceptions being cardiogenic shock when you don't want to elevate the legs, sometimes in cases of pulmonary edema and other respiratory compromise where lying down inhibits breathing, and trauma cases where leg elevation may compromise the spine - in the latter you can elevate the foot end of the rigid backboard.)
4. Provide calm reassurance
5. RAPID transport to the hospital where definitive care can be obtained, regularly monitoring the patient's vitals.
In particular, we DO NOT push meds, we DO NOT give food or liquids, and we (where I am) do not use shock trousers (MAST).

Paramedics have a broader scope of training and may have a wider set of tools available, but I'm not a paramedic, and unless you are you shouldn't be providing paramedic care.
