*”blood pressure” (BP) is the pressure of circulating ‘blood’ on the walls of ‘blood vessels’*
.
(when used without further specification, “blood pressure” usually refers to the ‘arterial pressure’ in the ‘systemic circulation’)
(‘blood pressure’ is usually expressed in terms of the ‘systolic’ (maximum during one heart beat) pressure over ‘diastolic’ (minimum in between two heart beats) pressure and is measured in ‘millimeters of mercury’ (mmHg), above the surrounding ‘atmospheric pressure’ (considered to be ‘zero’ for convenience))
(it is one of the ‘vital signs’, along with ‘respiratory rate’, ‘heart rate’, ‘oxygen saturation’, and ‘body temperature’)
(normal ‘resting blood pressure’ in an adult is approximately 120 mmHg systolic, and 80 mmHg diastolic, abbreviated “120/80 mmHg”)
(traditionally, ‘blood pressure’ is measured non-invasively using a ‘mercury manometer’ because these gauges are dependent upon only ‘gravity’, thus inherently more accurate than alternative types of ‘pressure gauges’)
(in research, the values obtained by an experienced knowledgeable physician using a ‘mercury manometer’ and ‘stethoscope’ listening for the ‘Korotkoff sounds’ are typically within 10 mmHg of the pressures measured via higher sophistication internal measurements of ‘central aortic pressures’ at ‘heart level’)
(other methods, which have become more dominant (for cost, time, convenience and concerns about potential ‘mercury toxicity’ issues) are inherently less accurate.
(‘blood pressure’ is determined, moment by moment, by the balance between ‘heart output’ versus ‘total peripheral resistance’ and varies depending on ‘situation’, ’emotional state’, ‘activity’, and ‘relative health/disease states’)
(it is ‘regulated’ by the ‘brain’ via both the ‘nervous’ and ‘endocrine’ systems)
(‘blood pressure’ that is low due to a ‘disease state’ is called ‘hypotension’, and pressure that is consistently high is ‘hypertension’)
(both have many causes which can range from ‘mild’ to ‘severe’)
(both may be of sudden onset or of long duration)
(long-term ‘hypertension’ is a risk factor for many diseases, including ‘heart disease’, ‘stroke’. and ‘kidney failure’)
(long-term ‘hypertension’ is more common than long term hypotension in ‘western countries’)
.
(long-term ‘hypertension’ often goes undetected because of ‘infrequent monitoring’ + the absence of ‘symptoms’)
