Does echo measure both diastolic and systolic pulmonary artery pressure

[Dentalmaniac]

Does an echo measure both diastolic and systolic pulmonary artery pressure. My echo result says estimated pulmonary artery pressure both at rest and post excercise was 25-35 mm Hg. Would this be a range for the systolic pulmonary artery pressure or is 25 diastolic and systolic 35? Can an echo measure diastolic pressure as well?

Does this mean my mean pulmonary artery pressure is around 23. I read online how the formula to calculate mean pulmonary artery pressure is (0.61 multiplied by systolic pulmonary pressure) +2

Is 23 towards the elevated side. Should I be concerned? I've also read that echo measures are just estimates and they can be off by as much as 10 mm Hg?

Someone's reassurance would be very helpful

There should be some clarification made after reading what I had posted.
QUOTE Analysis:  "CO (volume of blood pumped with each heartbeat) there is a variation of volume of blood pumped with each stroke to maintain a balance between left and right side blood flow) and abviously PAP will vary accordingly (stronger heartbeat,higher PAP".

Correction: Cardiac output (CO) is the stroke (each heartbeat) times 60 (one minute).  The correction doesn't change calculation methodology PAP = (CO x PVR) + PVP just the calculation of the variable.

As stated previously 35 mm Hg would be the systolic pressure (pumping phase).  Diastolic (chamber filling phase) about 15 mm Hg.

I gave you verbal expression with the posted question on your other post on the subject.. You seem very intelligent so I will give you the formula.  PAP is not as you have stated or if it is it is not very definitive.
Equation:  PAP = (CO x PVR) + PVP where CO = cardiac output, PVR = pulmonary vascular resistance, and PVP = pulmonary venous pressure. The PVP is essentially the same as left atrial pressure.

Ananlysis:  CO (volume of blood pumped with each heartbeat) there is a variation of volume of blood pumped with each stroke to maintain a balance between left and right side blood flow) and abviously PAP will vary accordingly (stronger heartbeat,higher PAP.

If there are blockages (clots) in the lungs or pulmonary artery (increase of resistance the heart pumps against,  and/or if there is narrowing, stiff pulmonary vessel the more resistance (increase of resistance will cause higher PAP). Also, normally there will be a variation of the diameter of the pulmonary vessel to maintain and compensate for a balance of blood flow between right and left side.  Plus pulmonary artery pressure (estimate with an echo, or better measurement with rightside cath.

Normally, mean pulmonary artery pressure is about 15 mmHg, and the pulmonary artery systolic and diastolic pressures about about 25 and 10 mmHg, respectively.
There are outer parameters of an acceptable, normal range for PAP.  Cardiac output has an acceptable range of 50 to 75% of filling capacity...obviously if the cardiac output is higher at a particular time interval there will be a higher PAP.  The difference of normal cardiac output has a variation of about 34%.  Therefore. just based on cardiac output variation the PAP can vary by 34%.

I have read your doctor's report (what you provide) to you, and there is not any opinion that is not in keeping with a good analysis and evaluation.  I think you may be reading information that is confusing, however, if you don't trust your doctor's evaluation then see another doctor.  Your doctor believes your PAP is within the acceptable range, and I have given you an insight to the measurement of PAP.  I hope this helps you by giving you an insight.
