ABSTRACT
Pulmonary function is a long-term predictor for overall survival rates in both genders. This study was undertaken to investigate the duration of facemask use and its effect on some respiratory parameters among apparently healthy normal weight male undergraduates. The aim of this study is to evaluate the effect of long duration of face mask use on some respiratory parameters among normal weight male undergraduates. Forty (40) subject were used for the study and when they came into the laboratory, they were made to sit while measurement of respiratory parameters were done in the following order: Pre-exposure to facemask, one hour after exposure to facemask, two hours after exposure to facemask, three hours after exposure to facemask, four hours after exposure to facemask, twenty four hours (24hrs) post exposure to facemask, the facemask used in this study was a surgical facemask. The respiratory parameters includes; respiratory rate, breath holding time, oxygen saturation level, peak expiratory flow rate. The results revealed no statistically significant difference among the test groups when compared with the control. It was therefore concluded that the prolonged use of facemask has no harmful effect in some respiratory parameter.
