I guess you're thinking this way because you've watched a foreign TV series about it ......
But have you ever thought about how much money it would cost to set up a rescue system like this? How many large hospitals in China have been built with helipads on their roofs for rescue helicopters to land on? And these aprons must also have a direct medical green channel for emergency patient transportation, otherwise this is all meaningless fantasy.
It is important to know that there are still many areas in China where even the most basic pre-hospital ambulance configurations via highway are still quite inadequate (local ambulance configurations and population ratios are not up to snuff; ambulances lack adequately trained paramedics; and vehicles are not equipped with the necessary first-aid equipment) and so on.
So in the current situation, it is clear that air medical rescue will not be listed as the first pre-hospital emergency development trend.
