A pulmonary shunt is the passage of deoxygenated blood from the right side of the heart to the left without participation in gas exchange in the pulmonary capillaries. It is a pathological condition that results when the alveoli of parts of the lungs are perfused with blood as normal, but ventilation (the supply of air) … Visa mer If every alveolus was perfectly ventilated and all blood from the right ventricle were to pass through fully functional pulmonary capillaries, and there was unimpeded diffusion across the alveolar and capillary membrane, there … Visa mer • Shunt equation • Cardiac shunt • Shunt (medical) Visa mer An irregular distribution of ventilation can occur in asthma, bronchiolitis, atelectasis, and other conditions, which have the effect of reducing the amount of oxygen present in some alveoli relative to others.
