Tim,
2 months ago my medical control was suspended because the BP for my patient was 80/50. The only other symptom possibly indicative of hypotension she exhibited was a headache. She also had drank alcohol earlier that day, it was hot and humid with no A/C, and her husband was very annoying to her. On scene she appeared stable- normal skin color, and able to recall information (with time- she had a substance abuse history which didn't help). While she was definitly a priority patient, her hypotension wasn't the primary reason I was concerned with. I was concerned about the longer- evolving renal failure.
Where did you get this definition?
