Varies.. We work 24 and run approximately 12-16 per 24, however; about 1/4 are critical care transports, the remainder are 911 calls. As well, about 50 % are in rural areas as the others are mixed in metro area.
Even though our area is lower population, I have to state that we use ALS skills quite a bit. Our medics intubate at least twice to three times a month (working 10 days a month) and that is with full medic trucks. So in ratio of response area of only 70K, we have some unhealthy folks to respond to.
