, -normal ratio is 0.8=amount by which perfusion exceeds ventilation


What is V/Q mismatch? - ANSWER✔✔-Ideally, ventilation is matched to perfusion in

order for adequate gas exchange. (normally with exercise V/Q approaches 1)


- imbalance in ventilation and perfusion of the alveoli




Apex of lung, V/Q = 3 (wasted ventilation)


Base of lung, V/Q = 0.6 (wasted perfusion)




*Both ventilation and perfusion are greater at the base of the lung*




V/Q = 0 --> airway obstruction/shunt physiology (100% O2 does not improve PO2)




PO2 - 40


PCO2 - 46
