Related to mean arterial pressure: pulse pressure

## mean arterial pressure

The intraarterial pressure that would exist at the output node of the heart if there were no arterial pulse, calculated as diastolic pressure + (systolic pressure minus diastolic pressure)/3.

## mean arterial pressure

An average of the blood pressure over the cardiac cycle, roughly equal to the diastolic pressure plus one third of the difference between the diastolic and the systolic pressure (i.e. the pulse pressure).

The experimental groups did not differ with respect to blood pressure at baseline as measured via Riva-Rocci (systolic blood pressure: t(78) = 0.23, p = .82, diastolic blood pressure: t(78) = 1.18, p = .24, mean arterial pressure: t(78) = 0.59, p = .56), heart rate at baseline (t(78) = 0.55, p = .58) and in terms of Body Mass Index (t(78) < 0.001, p = .99).
There was a statistically significantfaii in the heart rate, systolic, diastolic and mean arterial pressure (p-0.000) during infusion of dexmedetomidine.
Hypotension was treated with IV phenylephrine 50-100mcg boluses aiming to restore mean arterial pressure within 20% of baseline values.

The primary efficacy endpoint was the percentage of patients with a mean arterial pressure >= 75 mmHg or a 10 mmHg increase from baseline MAP at 3 hours following the initiation of study treatment without an increase in standard-of-care vasopressors.
Forty-eight hours into his admission, his lactate normalized but he was still requiring 0.9 mcg/kg/ min of norepinephrine and 0.04 unit/min of vasopressin to maintain a mean arterial pressure greater than 60 mmHg.
We next examined the risk factors for development of PH using logistic regression analysis of systolic blood pressure, diastolic blood pressure, mean arterial pressure, the proportion of arteriovenous fistula, serum BNP levels, phosphorus levels, CRP levels, albumin levels, hemoglobin levels, hypertensive nephropathy, right ventricular diameter, right ventricular outflow tract diameter, main pulmonary artery, left atrial diameter, interventricular septum thickness, ejection fraction, mitral regurgitation, and pericardial effusion.

Mid-BP predicts overall cardiovascular disease better than systolic BP alone, diastolic BP alone, pulse pressure, or mean arterial pressure, and its use permits researchers to study the effects of systolic and diastolic BP simultaneously.
