Abstract:
Objective To investigate the clinical value of pulsed pulmonary function in the diagnosis of chronic obstructive pulmonary disease (COPD).Methods 32 patients with chronic obstructive pulmonary disease admitted to Haiyang People's Hospital from March 2016 to March 2017 were selected as observation group .Another 32 cases without COPD were selected as control group .All the patients received pulsed pulmonary function test .The relevant indicators of oscillation technology and pulmonary function test indicators were compared between the two groups.Results The resonance frequency , total respiratory impedance , central airway resistance and peripheral airway resistance in the observation group were (16.9 ±1.5)kPa · L-1· s-1,(0.46 ±0.03)kPa· L-1· s-1, (0.56 ±0.05)kPa · L-1· s-1 and (0.15 ±0.03)kPa · L-1· s-1,which were significantly higher than those in the control group [(9.5 ±0.3)kPa· L-1· s-1,(0.26 ±0.01)kPa · L-1· s-1,(0.24 ±0.01)kPa· L-1· s-1, (0.02 ±0.01)kPao· L-1· s-1] (t=30.595,40.000,39.691 and 26.000,all P<0.05).The FEV1％ in the observation group was (41.5 ±1.9)％,which was lower than (81.1 ±2.0)％ in the control group(t=47.229,P<0.05).The FEV1/FVC level in the observation group was (49.5 ±3.3),which was lower than (81.9 ±2.6) in the control group(t=21.678,P<0.05).Conclusion The results of pulsed pulmonary function are synchronous and consistent with routine pulmonary function test ,especially for elderly ,pediatric and critically ill patients .
