prettyinpink Posted December 31, 2009 Report Share Posted December 31, 2009 I just finish my cardiopulmonary class so I can tell you what the currents ranges are SBP 120-139 pre-hypertension DBP 80-89 140-159 stage 1 hypertension 90-99 160+ stage 2 hypertension 100+Low bloodpressure can depend on the person. I read that when your brain loses 20% of its bloodflow you pass out as a safety mechanism ie to get you on the floor so blood gets back to your brain. I have a friend whose resting pressure is 85/60 and she feels fine where as if my pressure is that low I'm a half sec away from falling to the floor. Low blood pressure is defined by the symptoms a person experiences and not actual numbers typically. Quote Link to comment Share on other sites More sharing options...
potsgirl Posted December 31, 2009 Report Share Posted December 31, 2009 Low BP is usually considered anything under 90/60, but as PinP wrote, it's not too much of a problem if you're not symptomatic. My BP can get down to about 65-70/55, but I feel pretty horrible at that pressure. Cheers,Jana Quote Link to comment Share on other sites More sharing options...
