Abstract：Objective:To discuss the influence of the different suction depth on blood oxygen saturation of patients with chronic obstruc-tive pulmonary disease(COPD). Methods:66 COPD patients who could not have self - cough expectoration and change their body position by themselves and did not have the establishment of artificial airway were randomly divided into the experimental group and the control group(33 cases in each group). The shallow suction method was used in the experimental group and the deep suction method was used in the control group,SpO2 before and after suction,the decline of SpO2 and the time of SpO2 return to normal and to stability after suction, change of wheezy phlegm by auscultation and other safety indexes were compared between the two groups. Results:There were statistically significant differences in the comparison of SpO2 and the decline of SpO2 after suction in different depth,the time of SpO2 return to normal and to stability after suction between the two groups(P < 0. 01). Conclusion:Application of the shallow suction method can effectively help the patients with expectoration,and it has little influence on SpO2 of COPD patients,little injury of airway mucosa and less complication.
