Which method is not considered a way to drag a patient in an emergency?

Dragging a patient in an emergency typically involves methods that allow for quick and effective movement while minimizing further injury to the victim. The use of clothing, a blanket, or a technique employed by firefighters are all recognized methods of patient transport. These techniques focus on ensuring the safety and stability of the patient during the drag.

In contrast, submersion is not a recognized or safe method for dragging a patient. This action could lead to drowning or exacerbate any injuries the person may already have. Submersion does not provide a quick and controlled way to move someone who may be injured, especially if they are unconscious or unable to assist themselves. Therefore, it is not an appropriate or effective method in emergency situations.
