  1. The mean air flow, the average volume of air flow passing through a certain position of the nasal cavity; the mean air flow pressure, the average pressure of air flow passing through a certain position of the nasal cavity; the mean air flow velocity, the average velocity of air flow passing through a certain position of the nasal cavity; the mean air flow ratio, the mean ratio of the air flow through a certain section of the nasal olfactory cleft to the total air flow through the nasal cavity.
