HW appreciates our members and I did a search last night for you and found this thinking it may be helpful for you. I am also glad you are using the search feature here in the forum.
The left side of the heart is associated with systemic blood pressure, and the right side involves pressures associated with the pulmonary valve, pulmonary artery, and the lungs. It is accepted any value greater than 40 is in the range of pulmonary hypertension.
In medicine, pulmonary hypertension (PH) is an increase in blood pressure in the pulmonary artery, pulmonary vein, or pulmonary capillaries, together known as the lung vasculature, leading to shortness of breath, dizziness, fainting, and other symptoms, all of which are exacerbated by exertion. Pulmonary hypertension can be a severe disease with a markedly decreased exercise tolerance and heart failure.
In order to establish the cause, the physician will generally conduct a thorough medical history. A detailed family history is taken to determine whether the disease might be familial. A history of exposure to cocaine, methamphetamine, alcohol leading to cirrhosis, and smoking leading to emphysema are considered significant.
A physical examination is performed to look for typical signs of pulmonary hypertension, including a loud P2 (pulmonic valve closure sound), jugular venous distension, pedal edema, ascites, hepatojugular reflux, clubbing etc. Evidence of tricuspid insufficiency (pulmonary valve regurgitation/stenosis) is also sought and, if present, is consistent with the presence of pulmonary hypertension.
The pulmonary artery systolic pressures derived from a transthoracic echocardiogram are estimates based on the Bernoulli equation which uses with peak velocity from tricuspid regurgitation to estimate right ventricular systolic pressure. Normal values are less than 30 mmHg at rest. The point is that these are derived values and may vary as much as 5 to 10 points from examination to examination.
I do not have PH however, I do hope another member will be along to help answer your question.
Meanwhile I wish you a very pleasant week-end and look forward to getting to know you better.
