i have benn ufortunate enough to be involved in a couple of nasty motorcycle vs pedestrian RTC's... any suction is better than sticking your fingers into the patients mouth to remove blood clots... personally, i now carry a Vitalograph hand sucker... worth the £135 so that if i ever come across / end up involved in a nasty RTC again, i can hopefully clear their airway until some more help arrives...
