Ambulance plays a very important role in rescuing critically ill patients and responding to natural disasters and emergencies. However, domestic ambulance can only provide basic emergency treatment as equipments in it are still relatively backward. It was suggested in this paper that ambulance should be outfitted with portable endotracheal intubation and ventilator system for critically ill patients from the perspective of improved ambulance equipment, so as to create artificial airway quickly for dyspnea patients, which gains time and opportunity for further treatment to greatly improve the survival rate.
