Believe me they can and do leave patients with bleeding gums, had a guy just the other week with a bleeding gum while on the response car, came in as a red as it was classed as a haemorrhage, his family demanded a lift to the hospital as they said he would be safer with us, and not in one of there 2 cars outside, then the guy had the audacity to ask why we wernt using blue lights to get him there. the worse thing was that it had been bleeding since the previous night, he had waited till after they closed there chinese takeaway and then his family took him to hospital in there car, they had told him to wait till the next day and see his dentist. what a joke realy. then straight after that job a red call to ?bleeding from nose unknown origin. what a night cheers
