[Blood gases and acid-base balance in patients before and after treatment of obstruction of the nose].
Poor patency of the nasal passage has a negative impact on respiration. In 52 patients with increased nasal resistance blood gases and acid-base balance were measured according to the method of Astrup before and after surgical treatment of the upper respiratory organs. We found a significant increase of paO2 (on the average by 0.656 kpa; p less than 0.05) and of the buffer bases. The other parameters did not change to a statistically significant extent. The lower paO2 value in increased nasal resistance is most likely not due to hypoventilation. Altered nasopulmonary and nasothoracis reflexes exercise a negative influence on pulmonary mechanics and the laryngotracheobronchial tonus with subsequent alteration of the intrapulmonary distribution of the inspired air, and on ventilation-perfusion conditions of the lungs.
