What is the normal diastolic pressure for the pulmonary artery?

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).

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.

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.
