I don't think that would be a concern here - donor organs don't just suddenly show up at the blink of an eye, they need to be carefully extracted and prepped in an operating room. There's certainly enough time to prep a helicopter crew, if there isn't any on standby. That said, at least in Germany and the surrounding countries, there's a fairly dense network of rescue helicopters which are usually ready on the pad, crew on standby. They're supposed to be airborne within minutes.
