Why the study?
Does body position affect exercise capacity and pulmonary vascular pressure-flow relationships during exercise testing?
Does body position affect exercise capacity and pulmonary vascular pressure-flow relationships during exercise testing?
Body position does not affect maximum exercise testing of the pulmonary circulation when results are expressed as mPAP-cardiac output, though maximum workload is decreased in the semirecumbent position.
No takes yet. Share an insight, caveat, or question.
Semirecumbent and upright positions yield equivalent mPAP-CO slopes and VO2max; confirms interchangeable protocols for standardized pulmonary vascular exercise testing.
Forton et al. (2016) studied this question.
