ABSTRACT
It is known that the nasal cycle (NC) alongside with the mucociliary transport (MCT) plays an important role in the protection and restoration of the ciliated epithelium from exposure of various triggers including tobacco smoke. The objective of this work was to study the NC during smoking. The objectives of the study were to conduct daily registration of NC in active and passive smokers, determining MCT time before and after tobacco smoke inhalation, comparison of the results with those of healthy volunteers and correlation of the recorded NC and MCT indices of smokers and non-smokers.
Patients and methods. Daily nasal cycle monitoring was performed using rhinoflowmeter “Rhinocycle” in 40 smokers and 40 healthy adults aged 18–90 years. In the course of the study the changes of NC and MCT parameters were obtained.
Results. During the daily activity irregular nasal flow fluctuations predominated (77.5%) in most non-smokers. During night sleep NC had the classic nature in 42.5% of non-smokers. In 92.5% of cases smokers had irregular airflow fluctuations. The classic NC during day time was not recorded in any of the smokers. In active and passive smokers the relative volumetric flow (RVF) significantly changes from the age of 25 years in men and 30 years in women, which corresponds to the average smoking history of 10 years.
Conclusions. In most active and passive smokers the similar pattern of nasal airflow fluctuations was registered. Smoking reliably reduces RVF, decreasing the current fluctuation duration and resulting in the occurrence of acyclic NC intervals.
