[The effectiveness of measurement of nasal resistance in patients with sleep disordered breathing].
Nasal breathing disorder has been associated with the condition and treatment of sleep disordered breathing (SDB). In the current study, we investigated the utility of measurement of nasal resistance in patients with SDB. We examined the relationship between nasal symptoms and nasal resistance in 219 patients, and how the results affected the administration of nasal continuous positive airway pressure (nCPAP) in 34 SDB patients. Total nasal resistance was not significantly different between patients who were divided into two groups: those with nasal symptoms, and those without. The left-right ratio of nasal flow in the group with nasal symptoms was higher than in the group without nasal symptoms (p < 0.01). The mean percentage of nCPAP use was not significantly different between two groups divided by total nasal resistance. The mean percentage of nCPAP use > or = 4 hours was lower in the group in which total nasal resistance was more than 0.25Pa/cm3/sec (p < 0.05). The left-right ratio of nasal flow does not affect nCPAP use. We conclude that measurement of nasal resistance for confirming nasal breathing disorder is effective in patients with SDB, whether a patient complains of nasal symptoms or not.
