Request ALS if not already en route. If the BLS crew is able to deliver the patient to an emergency room within the same time it would take for the ALS crew to respond to the scene, the BLS crew should transport the patient.
If evidence of trauma or hemorrhage present see Initial Trauma Care Protocol
Consider other causes of shock
Apply cardiac monitor
Initiate two large bore IVs (or IO, if IV access in not available) of NaCl and titrate to a systolic BP of 90 mmHg if patient has no signs or symptoms of fluid overload
Reassess vital signs and peripheral perfusion; reassess for signs of pulmonary edema.
