Which rescue method is primarily used for patients needing immediate evacuation due to their condition?

The blanket drag is a rescue method particularly suited for evacuating patients who are in immediate need of assistance due to their critical condition. This method is effective in situations where a quick extraction is essential, allowing for the rapid removal of a patient from a hazardous environment without the need to move them into a different carrying position. The blanket drag involves placing the patient on a blanket and dragging them to safety, which can often be executed swiftly and with minimal disruption to the injured individual's condition.

This method is advantageous because it can quickly cover distance and allows for the transport of patients who may be incapacitated or unable to assist in their own evacuation. It is also useful because it requires fewer personnel than some other methods, making it a practical choice when there is an urgency to evacuate multiple patients or when resources are limited. Hence, the blanket drag stands out as a suitable technique for immediate evacuations under pressing circumstances.
