Use this calculation to summarize the supplied cardiovascular measurements with the stated equation and units, or to reproduce a value reported by a monitoring system.

Systolic pressure

A finite measured or assumed value from 70 through 300, expressed in mmHg.

Diastolic pressure

A finite measured or assumed value from 40 through 200, expressed in mmHg.

The implementation follows this calculation rule: Classify a blood pressure reading as normal, elevated, stage-1 or stage-2; systolic must exceed diastolic.^[1]

Blood pressure category

The calculated blood pressure category.

This is an arithmetic implementation, not a diagnosis. Hemodynamic measurements depend on acquisition method, timing, body size, rhythm, loading conditions, and clinical context; thresholds may differ among guidelines and patient groups. Its cutoffs are implementation rules and may not match every laboratory, species, population, or guideline.

Interpret the value with the underlying vital signs and measurement method. Direct clinical assessment, repeat measurements, and related indices such as stroke volume or cardiac index provide context that one summary value cannot.

• Total Blood Volume Estimate

  Estimate total blood volume from body weight using the documented reference value of 70 millilitres per kilogram.

• Cardiac Power Output

  Compute cardiac power output from cardiac output and mean arterial pressure.

• Ejection Fraction %

  Compute ejection fraction as a percentage of end-diastolic volume.
