Table 2

Transport characteristics.

	Transport method	Mean (95% confidence interval)
Relative transport Time^@*	Ambulance	79 (77.1–80.3)
	HEMS	39 (37.1–41.3)
Distance in km (road)*	Ambulance	29 (27.6–30.0)
	HEMS	62 (57.2–66.6)
Average speed in km/h*	Ambulance	79 (76.8–81.1)
	HEMS	131 (125.4–136.3)
Average time benefit in minutes*	Ambulance	7 (6.3–7.4)
	HEMS	32 (29.5–33.6)

* Results differ significantly (P < 0.001) between ambulance and HEMS
