It also discusses the common causes of pulmonary hypertension. Detail the Dana Classification of pulmonary hypertension, into 5 groups. Discuss the use of PR jet in the evaluation of the end diastolic and the mean pulmonary artery gradients. The mean TR velocity is also a method of calculating the mean pulmonary artery pressure. Discuss how the pulmonary artery pressure may not be a prognostic marker, as it can be of the same value at two different stages of cardiac output.
