| ABSTRACT Objective：To study thecorrelation between the degree of pulmonary ventilation function and nocturnal hypoxia occurs
in patients with chronic obstructive pulmonary disease.Methods： Selected 60 patients with stable chronic obstructive pulmonary diseasefrom
January 2012 to June 2013 in our hospital, divided into mild, moderate, severe , very severe four groups by pulmonary function, 15
cases in each group, monitoring records studied pulmonary function indicators and nocturnal oxygen index , comparing the differences of
indicators in each group , and analyze their relevance.Results： Among four groups COPD FEV1/FVC, FEV1, FVC, PEF, RV, RV / TLC,
MsaO2, ODI, WsaO2, LsaO2, SIT90% had differences (P<0.05);compared very severe and severe group FEV1/FVC, FEV1, RV, MsaO2,
ODI, WsaO2, LsaO2, SIT90% had differences (P<0.05); compared very severe and moderate group FEV1/FVC, FEV1, FVC, PEF, RV,
RV / TLC, MsaO2, ODI, WsaO2, LsaO2, SIT90% had differences (P<0.05);compared very severe and mild group FEV1/FVC, FEV1,
FVC, PEF, RV, RV / TLC, MsaO2, ODI, WsaO2, LsaO2, SIT90%had differences (P<0.05 ) ; compared severe and moderate group FEV1/
FVC, FEV1, FVC, PEF, RV / TLC, MsaO2 had differences (P<0.05); compared severe and mild group FEV1/FVC, FEV1, FVC, PEF, RV
/ TLC, MsaO2, ODI, LsaO2 had differences (P<0.05); compared moderate and mild group FEV1/FVC, FEV1, FVC, PEF, ODI had differences
(P<0.05). Pulmonary function in patients with COPD MsaO2 was positively correlated with FEV1 (r = 0.783, P<0.05).
Conclusion：pulmonary ventilation function correlated with the degree of chronic obstructive pulmonary disease in patients with nocturnal hypoxia. |
