Final answer:
EMS providers should continue performing CPR while transporting a patient on a stretcher.
Step-by-step explanation:
When it is necessary to perform CPR while transporting a patient on a stretcher, the EMS provider should continue performing CPR while transporting the patient. Performing CPR maintains the flow of blood until the heart can resume beating. By applying pressure to the sternum, the blood within the heart is squeezed out and into circulation, helping to maintain vital blood flow.
