Why do we calculate the rate pressure product?
This allows you to calculate the internal workload or hemodynamic response, as represented by rate pressure product, given the maximum heart rate and maximum blood pressure achieved.
What does rate pressure product indicate?
Both heart rate and blood pressure are incorporated in the rate pressure product (RPP), an indirect index of myocardial oxygen consumption that predicts cardiac function, morbidity, and mortality in patients with cardiovascular disease.
What is RPP a surrogate measure of?
Rate pressure product (RPP), calculated by multiplying SBP and HR, is a valid non-invasive surrogate measure of myocardial oxygen consumption. Coronary blood flow, cardiac workload and left ventricular hypertrophy have also been found to be relative to RPP.
How do you find a double product?
The double product was calculated by multiplying SBP by HR (mmHg/min).
What is normal rate pressure product?
Blood pressure and HR is a determinant of physical fitness since they both increase during exercise, but not at the same pace [20, 24, 25]. In subjects with BP between 110 to 120 systolic and 60-80 diastolic whereas resting heart rate (RHR) is 65 to 70 beats per minute (bpm) is considered normal .
How do you calculate the pulse pressure?
Advertisement. The top number (systolic) minus the bottom number (diastolic) gives you your pulse pressure. For example, if your resting blood pressure is 120/80 millimeters of mercury (mm Hg), your pulse pressure is 40 — which is considered a normal and healthy pulse pressure.
What is good pulse pressure?
The normal range of pulse pressure is between 40 and 60 mm Hg. Pulse pressure tends to increase after the age of 50.
What is the double product?
BACKGROUND. The double product (DP), consisting of the systolic blood pressure (SBP) multiplied by the pulse rate (PR), is an index of myocardial oxygen consumption, but its prognostic value in the general population remains unknown.
How do you calculate systolic blood pressure?
While palpating the radial pulse, inflate the cuff and note the pressure reading at the point the pulse is extinguished. This estimates the systolic blood pressure.
What is cardiac workload?
Cardiac oxygen demand is determined by workload, which is determined by cardiac output, which is determined by the heart rate and stroke volume (CO = HR x SV) and by the back pressure against the aortic valve (diastolic blood pressure) — which the heart must push against to open the valve and deliver the blood.

How do you calculate a map?
While MAP can only be measured directly by invasive monitoring it can be approximately estimated using a formula in which the lower (diastolic) blood pressure is doubled and added to the higher (systolic) blood pressure and that composite sum then is divided by 3 to estimate MAP.
What is the formula for calculating mean arterial pressure?
Physiology Fundamentals: Mean Arterial PressureMAP = SBP + 2 (DBP) MAP = 83 +2 (50) MAP = 83 +100. MAP = 183.
