A study was carried out on 62 asthmatic children for observed the acute effects of one hour of passive cigarette smoking on pulmonary function test before and after 1-hour exposure. Three parameters were measured: Forced vital capacity (FVC), Forced expiratory volume in one second (FEV 1), and Mid-Maximum expiratory flow rate (MMEF). Of those measurement MMEF showed the most important changed in 23% of patients. Passive smoking produced changed on 32.2% on asthmatic patients in any of pulmonary function test. Finally, correlation were made between parental cigarette smoking habits and skin test sensitivity at tobacco antigen, we didn't found correlation between this parameters.
