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.

Height

A finite measured or assumed value greater than or equal to 5e-324, expressed in cm.

Weight

A finite measured or assumed value greater than or equal to 5e-324, expressed in kg.

The implementation follows this calculation rule: Estimate body surface area with the DuBois formula.^[1]

Body surface area

The calculated body surface area in m^2.

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. The output is explicitly an estimate or proxy; preserve that label when reporting it.

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.

• BSA Mosteller

  Estimate body surface area with the Mosteller formula.

• Cardiac Index

  Compute cardiac index as cardiac output divided by body surface area.

• Total Blood Volume Estimate

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