Key result
Pressure oscillations were transmitted with less loss from the pulmonary artery to the occluded lobar pulmonary vein than from the pulmonary vein to the occluded lobar pulmonary artery.
Why the study?
Does the direction of pressure wave transmission affect the loss of pressure oscillations in the pulmonary circulation of patients without pulmonary hypertension?
Population

Asymmetric transmission may reflect compliance differences; hypothesis-generating for pulmonary pressure analysis without supporting practice change.
Observational
Does the direction of pressure wave transmission affect the loss of pressure oscillations in the pulmonary circulation of patients without pulmonary hypertension?
Asymmetric pressure wave transmission in the pulmonary circulation, likely due to compliance differences, provides a physiological basis for analyzing arterial and wedge pressure oscillations.
G. et al. (1967) conducted an observational in Without pulmonary hypertension. Pressure wave transmission from pulmonary artery to occluded lobar pulmonary vein vs. Transmission from pulmonary vein to occluded lobar pulmonary artery was evaluated on Pressure oscillation transmission loss. Pressure oscillations were transmitted with less loss from the pulmonary artery to the occluded lobar pulmonary vein than from the pulmonary vein to the occluded lobar pulmonary artery.
