Nobody wants it, but sometimes you still need an ambulance.
First and foremost, the patients themselves or the practices or hospitals are responsible for organizing an ambulance transport via one of the private ambulance companies.
This is not a rescue service operation.
The City of Bremen Rescue Service is only responsible if no private ambulance company can be reached or if transportation is only possible after more than 3 hours.

Unfortunately this specification of service has not yet been completely translated.
