a) Outline the WHO classification system for the causes of pulmonary hypertension.
b) Discuss measures to optimise right ventricular function in a patient with known pulmonary hypertension who is intubated for pneumonia. (70% marks)
In brief, the WHO recognises 5 major groups of disease which fall under the pulmonary hypertension heading:
These "PH WHO" groups are also known as the Dana Point classification system, so named because the original 2008 symposium on pulmonary hypertension was held in Dana Point, Ca.
