Pressures Generated During Nose Blowing
“Pressures Generated During Nose Blowing in Patients With Nasal Complaints and Normal Test Subjects,” Peter Clement and Hana Chovanova, Rhinology, vol. 41, no. 3, 2003, pp. 152-158.
The authors compared nasal resistance and pressures generated during breathing and nose blowing in patients with chronic sinusitis, septal deviations and a control group consisting of normal test subjects. The chronic sinusitis group generated pressures during nose blowing that were significantly higher (898 daPa for the left side and 913 daPa for the right side) than in the other two groups. The decongestion didn’t change the generated pressures very much. Pressures generated during nose blowing with both nostrils closed are much higher than pressures generated during nose blowing with one nostril open.
