Rhinomanometric Assessment of The Impact of High Altitude on Nasal Airway Resistance

Abstract

Aim of this study is to carry out a rhinomanometric assessment for the impact of altitude variation (1050–2215m) on nasal airflow. First of all, rhinomanometry standard values were specified in 100 healthy people (0.53 on the left; 0.55 Pa/cm³/sec on the right). 42 people were enrolled into the study. Nasal resistance was calculated for Group 1 when ascending from 1050m to 2215m and for Group 2 when descending from 2215m to 1050m. Nasal resistances and total nasal resistances were compared. Mean nasal resistances were determined as 0.54 Pa/cm³/sec on the right and 0.54 Pa/cm³/sec on the left for Group 1 and as 0.52 Pa/cm³/sec on the right and 0.59 Pa/cm³/sec on the left for Group 2. Altitude variation in Group 1 and 2 was detected to have no statistically significant effects on right and left nasal resistances. No variation in total resistance was determined either. Although ,Altitude variation from 1050 m to 2215 m or from 2215 m to 1050 m does not affect the nasal resistance in this study, due to the many factors that affect the physiology of the nose at high altitude a decisive conclusion can not be said. multi-factorial studies are needed.

Öz

Bu çalışmanın amacı yüksek irtifa değişikliğinin burun havayolu direnci üzerine etkisinin rinomanometrik olarak değerlendirilmesidir. Öncelikle 100 sağlıklı kişide rinomanometri standart değerleri belirlendi(sagda 0, 53 solda 0, 55 Pa / cm³ /sn).Çalışmaya 42 kişi alındı.2 gruba ayrıldı.Grup 1 de 1050 den 2215 m ye çıkışta grup 2 de ise 2215 den 1050 ye inişte nazal direnç hesaplandı.Nazal dirençler ve total nazal dirençler karşılaştırıldı. Grup 1 de sagda 0,54 solda 0,54 grup 2 de ise sagda 0,52 solda 0,59 Pa / cm³ / sn ortalama nazal direnç tesbit edildi. Grup 1 ve 2 de irtifa değişikliğinin sag ve sol nazal dirençlerde istatiksel olarak anlamlı bir etkisinin olmadıgı gözlendi (Mann Whitney u testi). Total dirençte de degisiklik tesbit edilmedi (Student t testi). Bu çalışmada alçaktan yükseğe veya yüksekten alçağa irtifa değisikliği nazal direnci etkilememektedir şeklinde sonuç çıkmasına rağmen yüksek irtifada burun fizyolojisini etkileyen çok sayıda faktör olduğundan kesin sonuç söylenemez.Çok faktörlü çalışmalara ihtiyaç vardır
