A study of effect of duration of ac exposure on spirometric parameters
Life without machines is impossible nowadays, may it be Air conditioners (AC),vehicles or mobiles.ACs are being commonly used in homes and offices. AC causes air to become cold and dry. This can adversely affect the health of the AC users, particularly respiratory system. The present study was done to compare the spirometric parameters of AC users with non users and to study the effect of duration of AC exposure on spirometric parameters.100 healthy, non smokers of age 25 – 50 yrs exposed to AC were selected as study group.
