Does the pulse contour method applied to pulmonary artery pressure records accurately measure stroke volume compared to indicator dilution curves in patients?
Measurement of stroke volume from the pulmonary artery pressure contour correlates well with dye dilution methods and is a potentially valuable technique for serial haemodynamic monitoring.
Zacharoulis et al. (1975) studied this question.
