Nasal eupnoeic inhalation of cold, dry air increases airway resistance in asthmatic patients.
The aim of this study was to establish a relationship between bronchial hyperreactivity to carbachol and reflex bronchomotor response to the activation of cold receptors in the nose, and also to examine whether any differences exist between asthmatic patients with or without symptoms of rhinitis. The changes in interrupting resistance (Rint) induced by nasal eupnoeic inhalation of cold (-5 degr...
متن کاملChanges in airway resistance induced by nasal inhalation of cold dry, dry, or moist air in normal individuals.
Nasopulmonary bronchomotor reflexes elicited by mechanical or irritant stimulation of the nose have been described in animals and asthmatic patients. However, few studies were devoted to the consequences of nasal breathing of cold and dry air or of only dry or only moist air on the bronchomotor control in normal individuals. The present study reported changes in interruption resistance (Rint) m...
متن کاملActive anterior rhinomanometric (AAR) evaluation of nasal airway resistance in normal Iranian sample
Abstract: Background: The most important and complex phenomenon of respiratory function of the nose is related to different nasal anatomy. The differences in facial anatomic structure between different races may also be reflected in nasal resistance and airflow. Caucasians has different facial anatomic structure which is the reflection of intranasal resistance or consequence of airflow. The...
متن کاملImpact of endoscopic endonasal pituitary surgery on nasal airway patency
Background: Nose is used as a corridor in endoscopic endonasal transsphenoidal approach (EETSA) for pituitary adenoma. Thus, it may affect the nasal airway patency, function and sinonasal-related quality of life. The aim of this study is to objectively and subjectively evaluate these effects. Methods: In this prospective study, 43 patients with pituitary adenoma who were c...
متن کاملHandgrip-induced airway dilation in asthmatic patients with bronchoconstriction induced by MCh inhalation.
We investigated the effects of static and rhythmic handgrip on the time course of recovery of airway resistance measured with the interrupter technique (Rint) following bronchoconstriction induced by methacholine (MCh) inhalation in 17 asthmatic patients. On three separate occasions, a 100 +/- 5% increase in baseline Rint was induced by MCh inhalation. Subsequently, patients either rested [cont...
