What is the purpose of rescue breaths before lowering a victim?

The purpose of administering rescue breaths before lowering a victim is primarily to prevent throat tissue swelling. When a person is unresponsive and not breathing, it may indicate a potential airway obstruction or compromise. Providing rescue breaths helps inflate the lungs with air, which can facilitate oxygen exchange and ensure that the airway is open, reducing the risk of swelling in the throat tissues.

The other options do not align with the primary goal of rescue breaths. Increasing blood pressure, for instance, is not a direct effect of administering rescue breaths and does not align with the immediate needs of the victim at that moment. Establishing trust and ensuring a comfortable landing are also not directly relevant to the immediate action of delivering rescue breaths, which is focused on preserving the victim’s airway and ensuring adequate oxygenation until further help can be rendered.
