Mean Pulmonary Arterial Pressure


Mean Pulmonary Arterial Pressure


Mean Pulmonary Arterial Pressure is calculated by all of the following formula Except


[A] MPAP = (SPPA + 2 x DPPA ) / 3
[B] MPAP = (0.61 x SPPA ) + 2 mmHg
[C] MPAP = 4 x PR peak velocity2 + right atrial pressure (RAP)
[D] MPAP = 120 – (0.62 x RVOT acceleration time)



Mean Pulmonary Arterial Pressure is calculated by

  • MPAP = (SPPA + 2 x DPPA ) / 3
  • MPAP = (0.61 x SPPA ) + 2 mmHg
  • MPAP = 4 x PR peak velocity2 + right atrial pressure (RAP)
  • MPAP = 90 – (0.62 x RVOT acceleration time)

SeverityPVAT
Normal PAP> 130 msec
Borderline PAP100 – 130 msec
Mildly elevated PAP80 – 100 msec
Severely elevated PAP< 80 msec / systolic notch
