What is the normal diastolic pressure for the pulmonary artery?

10-15. Pad will often reflect as a surrogate for left atrial pressure (lap), and therefore should range in the 10-15 range. In pulmonary htn, these values may be elevated above the level of lap, in which case the 2 do not correlate.
4-12 mmHg. Normal pulmonary diastolic pressure is 4-12 mm of mercury. There are many conditions that may raise this pressure. Low pressure readings may indication volume loss (ie loss of blood or dehydration).
Around 10. Normal pulmonary artery pressure is about 25 over 9. We don't diagnose pulmonary hypertension unless the mean pressure is 25 or higher together with a normal left atrial pressure and increased pulmonary vascular resistance.
