In this study 100 cases of C. O. P. D were classified according to dialectical method of traditional Chinese Medicine. By infusion lung imaging it was shown that 76 cases were abnormal in blood supply in which the category of "fei xin qi xu" ("weak in heart and lung breath") got the first place and followed by the category of II order "fei qi Xu" ("weak in lung breath"). It was considered that the change in lung infusion imagings were the evidence of "fei xu zheng" ("weak-lunged symptom") "xin xue yu zu"("stasis of heart blood") and might be used to guide the treatment and to observe the efficiency of "huo xue hua yu" ("invigorating blood circulation and eliminating stasis") therapy
