Why the study?
Does the pressure profile after pulmonary artery occlusion provide a more precise measurement of pulmonary capillary pressure than pulmonary wedge pressure?

Pulmonary capillary pressure may diverge from wedge pressure; leaves open whether occlusion profiles refine estimates in thoracic surgery.
Does the pressure profile after pulmonary artery occlusion provide a more precise measurement of pulmonary capillary pressure than pulmonary wedge pressure?
Measurement of effective pulmonary capillary pressure using the pressure profile after pulmonary artery occlusion provides a more precise capillary filtration pressure than pulmonary wedge pressure.
Cope et al. (1986) studied this question.
