Default ventilation perfusion defect

Hi all
I know that Ventilation defect is normal perfusion with impaired oxygen delivery to alveoli.
My question is, is pulmonary edema a ventilation defect too as oxygen is not delivered completely bcos of fluid in it?
So pulmonary edema both ventilation defect and diffusion defect?

ventilation should be affected cos the diffusion distance across the alveoli to the capillaries has increased, but then, from the pathophysiology of pulmonary edema; there is congestion from left sided heart failure so perfusion is basically reduced too. i think v/Q would increase

v/q decreases, it is certainly a ventilation defect.
