Objective:To observe the effectiveness of extrasomatic vibration sputum discharge machine to patients with COPD.Methods:A total of 65 cases of COPD were randomly divided into experimental group(n=33) and control group(n=32)

patients in experimental group accepted extrasomatic vibration sputum discharge machine

while patients in control group accepted aritificial beat sputum elimination.The daily sputum volume within 1 week

heart rate

respiration

SPO2 and artery blood gas index in 1d and 4d with oxygen inhalation 3L/min

SPO2 in 7d without oxygen inhalation were compared for the 2 groups.Result:The daily sputum volume in 1d

2d

3d

4d

5d increased obviously and in 6d

7d decreased notably in experimental group compared with control group and the difference was significant.For the experimental group

the heart rate and respiration decreased notably in 3d compaed with those before hospitalization

and the artery blood gas index had significant difference between 1d and 3d.The heart rate and respiration of control group did not decrease significantly in 3d

and there was no significant difference of the artery blood gas index between 1d and 3d.After 30min without oxygen inhalation

SPO2 of experimental group increased that of control group.Conclusion:The extrasomatic vibration sputum discharge machine is better than aritificial beat sputum elimination

which decrease the labour intensity of medicine and nursing staff as well as improves nursing quality and shortes hospitalization time.Further

it is easy for the patients to accept it.
