Document Summary
Normal blood pressure (bp) is considered to be 120/80 mm hg. Hypertension is considered to be consistently elevated blood pressure. Systolic blood pressure above 140 mm hg. Or diastolic blood pressure above 90 mm hg. Blood pressure created by the exertion of blood against the arterial walls during contraction of the heart"s ventricles (during pumping) Blood pressure created by the exertion of blood against the arterial walls during relaxation of the heart"s ventricles (not during pumping) The difference between systolic and diastolic bp (pp = sbp - dbp) Mean arterial the average pressure exerted against the arterial walls per cardiac cycle. Map = dbp + ( ( sbp - sdp ) ) Map = cardiac output x total peripheral resistance. Cardiac output (co) the amount of blood ejected through the heart over a minute (co = sv x hr) The amount of blood pumped out of the left ventricle and into the body (systemic circuit) with every single contraction.
