CONTINUED medical contributions have been made in the field of pulmonary physiology, especially in the last decade, with the development of medical electronics. However, little attention has been paid to nasal breathing by most pulmonary physiologists. By applying the methods which are widely employed for pulmonary function tests, to nasal as well as mouth respiration, we have shown that nasal obstruction has a definite influence on pulmonary functions.1-4
This paper deals with changes in pulmonary mechanics in patients with nasal obstruction, through the separation of pulmonary resistance into its components, airway and pulmonary tissue resistance. Preoperative and postoperative data is presented showing the return of various abnormalities in function to normal following successful nasal surgery upon the obstructed nose.
Review of Literature
A few pulmonary physiologists such as Speizer et al5 and Ferris et al,6 using their own techniques, measured the resistance of various parts of the
