- POEMS syndrome is a rare plasma cell dyscrasia that presents with polyneuropathy and other systemic findings. Patients with 1-3 bone lesions and a negative bone marrow are often treated with involved field radiation therapy as the initial and potentially definitive therapy. Long term outcomes of pat

概念
- 肺胞気から肺毛細血管に至るガス移動効率の指標
- 肺毛細血管内を通過する血液の気層との接触時間は0.75sあれば酸素化に影響はない。この接触時間が短くなる、すなわち血流速度が増加した状態では酸素化が不十分となり拡散能の低下として認められる。血流速度は運動時や、あるいは毛細血管が破壊されたり閉塞したりして血管床が減少した病態で上昇する。(SPU.24)
- 20-30ml/min/Torr(YN.I-27)
方法
- 4種混合ガスを用い、最大呼出後急速に最大吸気位まで吸気し、10秒息止めをした後、急速に最大呼出をしCOガスの吸収量を測定して肺拡散能を検査する。
DLCOを低下せしめるファクター
- 肺間質、気道、肺血管の異常
- (1) 肺胞から肺毛細血管赤血球内ヘモグロビンに至るまでの拡散距離の増加
- (2) 肺胞・肺毛細血管の有効拡散面積の減少
- (3) 換気、血流、拡散能力の肺内不均等分布
- YN.I-27

DLCO上昇
- 軽度肺うっ血 → 肺血流量の増加により軽度上昇(SPU.354)
