Title : FEV1 / FEV6 microspirometry – as a screening tool for chronic obstructive pulmonary disease.

Abstract:

Background: Various studies in India have found that the prevalence of undiagnosed COPD is between   4  to  18.2   %.  The  microspirometry,   which is based on measurements  FEV1  (forced expiratory volume in 1 second),  FEV6 (forced expiratory volume in 6 seconds), and their ratio, has been found 'a reliable screening tool' in various studies, which can reduce underdiagnosis of COPD in primary care.   
Aim:  Validation of handheld FEV1/FEV6  micro spirometer in an   Indian population.  
Method:  A  pilot sample of  141  patients was taken for the study.  Patients with respiratory symptoms and exposure to risk factors for COPD were subjected to pre-bronchodilator (BD) FEV1/FEV6 microspirometry and post-BD FEV1/FVC (Forced vital capacity) full spirometry. A pre-BD FEV1/FEV6 value < 0.88 as measured with the Piko-6 micro spirometer was compared with a post-BD FVC < 0.70  from diagnostic spirometry.  
Result: The majority of our study participants (53.9%) were having COPD, while 46.1%  didn't have the condition.  For an FEV1/FEV6 ratio of 0.88, the sensitivity and specificity of the test are 84% and 51% respectively.
Conclusion: The situation of underdiagnosis of COPD could be improved through screening using portable/hand-held devices simpler than conventional spirometers in specific health care settings to reach a higher percentage of the at-risk population.
