Summary

The aim of this study was to compare the acute effects of second hand smoke exposure between nasal and oral breathing and to assess the potential protective role of the nose during acute exposure, in exposure conditions similar to those within a bar where smoking is permitted.

Conditions

  • Second Hand Smoke Exposure

Interventions

OTHER

exposure to second hand smoking

The duration of the exposure to second hand smoke both days was for 20 minutes within a 250mgr/m3 concentration box room. A smoking machine was used, which mimics the smoker (up to 6 breaths per minute in tobacco volume 80ml for each inhalation). The exposure was sometimes with closed mouth and others with closed nose in random sequence.
