What is the first step in controlling arterial bleeding?

The first step in controlling arterial bleeding is to apply manual pressure to the wound. This method directly addresses the source of bleeding by compressing the injured area, which can help immediately slow or stop the flow of blood. This technique is critical in emergency situations where quick action is needed to prevent significant blood loss and stabilize the patient.

While the other options may have their places in managing blood loss, they are typically secondary interventions. Applying a tourniquet is appropriate in cases where direct pressure is not effective or when dealing with severe extremity injuries, but it’s not the first action. Elevation of the limb can assist in reducing blood flow to the area, but its effectiveness may be limited in severe bleeding. Application of ice can help reduce swelling or pain, but it does not directly address the blood flow. Therefore, manual pressure remains the most immediate and effective initial response in controlling arterial bleeding.
