Mean Arterial Pressure
Compute mean arterial pressure from a cuff systolic and diastolic using the standard physiology approximation MAP = (2*DBP + SBP) / 3.

Example
- Systolic BP
- 120 mmHg
- Diastolic BP
- 80 mmHg
Result: MAP 93.3 mmHg

What this is
Sophie Well returns the MAP in mmHg, the pulse pressure (SBP - DBP), and the rounded ratio so the bedside math matches the monitor display.
When to use it
Reach for this when the chart shows only the SBP/DBP cuff value and you need a perfusion proxy - sepsis bundle targets (MAP >=65), neuro-ICU thresholds, or post-cardiac-arrest goals. The formula assumes a normal heart rate and a roughly sinusoidal pressure waveform; on an arterial line or in shock, the monitored MAP is more accurate than this estimate.
How this is calculated
Standard physiology: MAP = ((2 * DBP) + SBP) / 3.
