Abstract

In this single-blind, crossover pilot study, supplemental oxygen at 2 L/min during 6-min walk test reduced Cardiac Effort in patients with pulmonary arterial hypertension, while 6-min walk distance remained unchanged. This decrease suggests improved physiology for an unchanged workload. Continuous electrocardiogram heart rate monitoring adds considerable value to the 6-min walk.
