An EMT friend told me that the best times to call an ambulance are when you need immediate medical attention, if it would take you much longer to get to the hospital yourself, or if there's a reasonable chance you would distract the driver (e.g. screaming pregnant woman, someone heaving and clawing for air during an asthma attack). While having broken/severed fingers sounds awful, I would probably make the same call (take this as hearsay + a non-medical opinion)
