- Which<br/>one is not correct about ventilation/ perfusion ratio? () A: the<br/>normal value is 0.84 in resting state B: its<br/>decreasing means the increasing of physiologic dead space C: its<br/>value reaches to 3 at apex of lung D: its<br/>value decreases at inferior part of lung because there is not<br/>sufficient gas exchange there E: when<br/>it undergoes embolism in pulmonary artery, its value decreases
