Introduction. Negative inspiratory pressure is an important
factor in the pathomechanism of sleep apnoea syndrome. It
causes pharyngeal walls collapse. This pressure depends on
upper airway resistance. Anterior rhinomanometry (ARMM)
and pulsoxymetry are methods used to measure the nasal flow
Aim. The aim of the study was to investigate the nasal resistance
in patients with sleep-disordered breathig (SDB) and how the
body posture changes rhinomanometry results in patients with
SDB, as well as to assess the saturation from the results of sleep
Material and methods. The study group consisted of 60 patients:
26 women and 34 men, average age: 51. According to the results
of pulsoxymetry, the patients were divided into two groups:
1. examined group: with SDB (desaturation index (DI4)>5);
2. control group: without SDB (desaturation index (DI4)<5).
The next step was active anterior rhinomanometry (ARMM). The
test was carried out in two postures: 1. sitting posture (vertical);
2. supine posture (horizontal) – performed after about 15 minutes
of resting in that posture. We compared the number of pathological
results of ARMM in both groups in two postures.
Results. The nasal flow resistance evaluated by ARMM in both
postures was more frequently elevated in patients with sleep
apnoea syndrome. The number of pathological results of ARMM
was significantly higher in the group of patients with sleep apnoea
syndrome in supine posture compared to the sitting posture.
Conclusions. There is a relationship between increased nasal
resistance and SRB. Active anterior rhinomanometry should be
routinely performed in supine posture, especially when sleep
apnoea syndrome is suspected.
