Systolic blood pressure is the measurement of standard clinical systolic blood pressure. Measured using standard oscillometric algorithms, and closely represents values taken by auscultatory techniques using mercury cuff sphygmomanometry and Korotkoff sounds (K1). Reference
Diastolic blood pressure is the measurement of standard clinical diastolic blood pressure. Measured using standard oscillometric algorithms, and closely represents values taken by auscultatory techniques using mercury cuff sphygmomanometry and Korotkoff sounds (K4). Recommended for children. Reference
Diastolic blood pressure is the measurement of standard clinical diastolic blood pressure. Measured using standard oscillometric algorithms, and closely represents values taken by auscultatory techniques using mercury cuff sphygmomanometry and Korotkoff sounds (K5). Recommended for adults, and for comparison with JNC-7 guidelines (K1/K5). Reference
End systolic blood pressure measures central arterial blood pressure at end-systole. Measured using proprietary Pulse Dynamics waveform pattern-recognition algorithms.
End diastolic blood pressure measures central arterial blood pressure at end-diastole. Also equivalent to K5. Measured using proprietary Pulse Dynamics waveform pattern-recognition algorithms.
Mean arterial pressure is the average blood pressure over time, measured using proprietary Pulse Dynamics pattern-recognition algorithms. It can also be estimated using MAP = 1/3 Systolic + 2/3 Diastolic.
This is an index that is used clinically to characterize the contractile ability of the heart.
It is believed that maximum dP/dt is a reasonable index of the initial velocity of myocardial contraction.
The maximum left ventricular dP/dt, which is normally about 1600 mm Hg/sec, tends to be less than
1200 mm Hg/sec in patients with disorders of the left ventricular myocardium.
Cardiac output is one of the most basic measurements of cardiovascular function. It is usually defined as the
volume of blood ejected per minute by either ventricle, and since the two ventricles are usually in balance, the
two outputs are essentially equal.
Cardiac Output (CO) is calculated as: CO = SV X HR [L/min]
The compliance is a relatively new cardiovascular parameter that was developed to assess the elasticity or rigidity
of the heart and arteries. The compliance is calculated as
Change in Volume/Change in Pressure
In order to assess the systemic compliance, which is the compliance of the heart and large arteries, the change in
volume of the heart (stroke volume) is divided by the change in pressure within the heart (systolic pressure minus the diastolic pressure):
SVC = SV/(SBP-DBP) x [ml/mmHg]
The systemic vascular resistance is the effect of the vessels
resisting flow. This resistance is primarily a function of vessel size and of the number of vessels open. It can be calculated by:
SVR = MAP/CO [mmHg/(L/min)]
Brachial Artery Distensibility is defined as the compliance divided by the arterial volume [(dV/dP)/V],
or the percentage change in volume per mmHg change in pressure
BMI = Weight/(Height * Height) * 10000 (kg/(cm*cm))
Numerical value of weight in relation to height. Can be used to assess whether patient is underweight, normal weight, overweight, or obese. Weight value used in calculation is latest value entered for patient.
