Formula
MAP = DBP + 1/3 x (SBP - DBP)
Enter SBP and DBP to see the worked formula.
Reference bands
Critical low-perfusion risk
MAP below 60 mmHg can signal low perfusion risk.
< 60 mmHg
Below common septic-shock target
This sits below the common MAP >= 65 mmHg septic-shock target.
60-64 mmHg
Common adult reference band
A common adult reference band for mean arterial pressure.
65-100 mmHg
Elevated pressure context
Higher MAP can reflect elevated arterial pressure context.
> 100 mmHg
