Which of these actions does NOT stop the irrigation process?

The action that does not stop the irrigation process is the continued saline supply. In the context of wound irrigation, the goal is often to remove contaminants and debris while ensuring that the affected area is kept moist and clear. As long as saline is available and being utilized, the irrigation can continue, allowing for effective cleaning and treatment of the wound.

The other choices involve circumstances that would genuinely halt the irrigation. Running out of supplies directly prevents further irrigation, as there would be no saline available to continue the procedure. Once a casualty reaches a medical treatment facility (MTF), the responsibility shifts to medical personnel, and the actions taken there would represent a change in protocols that typically conclude pre-hospital care interventions, including irrigation. Lastly, if too much time has elapsed—such as 20 minutes—without continuing irrigation, it could indicate that the situation needs to be reassessed or that the current efforts are ineffective, leading to a cessation in the irrigation process while more appropriate actions or treatments are considered.
