A V/Q lung scan was obtained in a patient with LLL collapse who was receiving IPPV and PEEP. This revealed absent ventilation and hyperperfusion to the collapsed lobe. After a reduction in PEEP from 12 to 5 cm H2O, a repeat V/Q scan showed a more even distribution of pulmonary perfusion. Arterial hypoxemia improved.
对一名正在接受间歇正压通气（IPPV）和呼气末正压通气（PEEP）的左肺下叶萎陷患者进行了通气/灌注（V/Q）肺扫描。结果显示萎陷肺叶无通气但血流灌注过多。将呼气末正压从12厘米水柱降至5厘米水柱后，重复进行的通气/灌注扫描显示肺灌注分布更为均匀。动脉低氧血症有所改善。
