Septic Shock: caused by bacteria
Anaphylactic Shock: caused by hypersensitivity or allergic reaction
Cardiogenic Shock: from heart damage
Hypovolemic Shock: from blood or fluid loss, and neurogenic shock from spinal cord trauma

Lay the patient down and elevate their legs and feet slightly. Do not attempt if you think this may cause pain or injury.
Loosen tight clothing, to free them of constraint. If the patient is shivering, cover them with a blanket.
Don't let the person eat or drink anything.
Keep them calm by speaking with them until help arrives.
If the person vomits or begins spitting up blood, turn them onto a side to prevent choking.
