The answer to the question is-
Blood flow though some areas of your lungs is decreased even though you are taking adequate breaths.
<h3>
What is pulmonary embolism?</h3>
A ventilation-perfusion mismatch results from a pulmonary embolus that reduces blood flow but has no impact on ventilation. It describes a diffusion issue when it says, "Oxygen transfer into your blood is delayed because of thick membranes." The final two comments discuss a ventilation-perfusion mismatch with sufficient blood flow but inadequate ventilation.
A blood clot in the lung's arteries blocks one or more of them, causing pulmonary embolism.
Blood clots that leave the legs or, in rare cases, other parts of the body are what typically cause a pulmonary embolism (deep vein thrombosis).
Chest pain, coughing, and shortness of breath are symptoms.
