What is the difference between 'Hot' and 'Cold' loading in patient transport?

• A. 'Hot' loading refers to loading patients while the helicopter is running, while 'Cold' loading is done when the helicopter is off.
• B. 'Hot' loading is for children only; 'Cold' loading for adults only.
• C. 'Hot' loading uses more oxygen; 'Cold' uses less.
• D. There is no difference; they are the same.

Answer: (A)

The difference is about whether the helicopter is running and the rotor is turning during the loading process. Hot loading means you load a patient while the helicopter is on and the rotor is turning, which conserves time for urgent transports but introduces risks from rotor wash, debris, and aircraft movement. Because of that, hot loading requires tight safety procedures, quick securement, and clear communication to minimize the danger.

Cold loading, on the other hand, is done with the helicopter engines off and the rotor not turning, providing a calmer, more controlled environment. It takes more time but reduces the immediate hazards to crew and patient, making it the safer choice when the situation allows.

The other statements don’t describe loading conditions and aren’t relevant to the difference between hot and cold loading.
