OK, we want to provoke some thoughts here.
An emergency trolley, or crash cart, is used to deal with critical situations, and should be available in all wards (except first aid and intensive care: they are already organized for that).
The trolley (have a look at our Persolife) must contain emergency medications, a defibrillator, an Ambu bag, a small oxygen bottle, a cardiac massage board, an IV pole and a suction pump and must allow responders to use it as a mobile station.
An emergency situation requires rapid action, and tools, instruments and medications must be at hand.
