What is the first step in the chest pressure arm lift method?

The first step in the chest pressure arm lift method is to press. This step involves applying downward pressure on the chest, which is crucial for creating the necessary clearance in the airway during a rescue or first aid situation. By pressing firmly on the chest, you help to ensure that any blockage is addressed, and it allows for more effective movements in the following steps, such as lifting the arms. This foundational action is critical as it sets the stage for the subsequent techniques used to assist someone in distress, particularly in cases of choking or cardiac arrest scenarios. The other options do not accurately represent the initial action required in this method, making "press" the definitive starting point.
