Addendum to 'Continuous Assessment of Nasal Airflow Resistance by Adaptive Modeling'

This addendum adds to the analysis of 'Continuous assessment of nasal airflow resistance by adaptive modeling' (Seppänen et al 2009 Physiol. Meas. 30 1197–209). The technical repeatability tests of the new nasal resistance measurement system presented here show that the resistance values remained very stable during two successive measurements indicating excellent repeatability.
