Target Blood Pressure Calculator

Check if BP is in target range.

About Target Blood Pressure Calculator

Mean arterial pressure for Target Blood Pressure weights the longer diastolic phase of the cycle, giving the number that drives perfusion to vital organs. MAP is what organs actually see, so it is the value that matters for perfusion, not the peak systolic.

Formula

Target Blood Pressure

MAP = diastolic + (systolic - diastolic) / 3

MAP
The average arterial pressure during one cardiac cycle

Worked example

With the default values below, Target Blood Pressure Calculator returns Mean Arterial Pressure of 93.3. Change any input above and every figure here is recalculated in your browser.

Assumptions and limits

  • The result is derived only from the 3 inputs listed above. Anything not among them is not part of the calculation.
  • In particular, this calculator does not take inflation, tax, fees or charges or compounding frequency into account.
  • Figures are rounded for display to 1 decimal place, so totals built from several rounded parts can differ slightly from the unrounded arithmetic.
  • These are educational and reference calculations only. They are not a diagnosis, not a substitute for measurement or laboratory testing, and must not be used to start, stop, time or change any medication or treatment. Reference thresholds differ between national guidelines and do not account for your individual clinical context. Discuss any result that concerns you with a qualified healthcare professional, and seek urgent medical attention for acute symptoms rather than relying on a calculator.
  • This is an estimate for general information and not professional medical advice. See the full disclaimer for the limits that apply to this kind of calculator.

How these calculators are built and tested is described on the Methodology page. If a figure looks wrong, please report it.
