Objective:
To study the effect of OSAHS on adult nasal-cycle.
Method:
The nasal cycle of 20 healthy adults, 18 patients of snoring and 22 patients of OSAHS were examined with acoustic rhinometry, which was performed every 30 minutes in 7 hours.
Result:
The ratio of nasal cycle in healthy adults was (19/20, 95.0%), in snoring patients was (15/18, 83.0%), in patients of OSAHS was (15/22, 68.2%). The mean alteration amplitude of nasal cycle in healthy adults was significantly larger than that in patients with OSAHS (P < 0.05). The distribution of the healthy adults and patients with OSAHS between the typical cycle categories was significantly different (P < 0.05).
Conclusion:
The characteristics of nasal-cycle in of OSAHS patients were different with healthy adults, which maybe owing to change of physical function of basal cavity.

Special considerations while measuring oxygen saturation
Ensuring accuracy in vital sign recordings while prioritizing patient comfort and minimizing anxiety is important.
Assessment of Ventilation I: Respiratory Rate
A Ventilation assessment is critical for monitoring a patient's health status. Respiration, one of the most accessible vital signs, provides insights into the function of numerous body systems and can indicate serious health issues, such as brainstem injuries from head trauma.
Critical Guidelines for Assessing Ventilation:
Suctioning the Nasopharyngeal Airway
Equipment Required
Assessment of Ventilation II: Respiratory Depth and Rhythm
Respiratory depth measures the volume of air inhaled or exhaled during a breath. It can vary from shallow to deep and typically remains consistent when a person is at rest or asleep. Occasionally, individuals will automatically inhale deeply, known as sighing, which inflates the lungs with more air than normal breathing.
To assess respiratory depth, observe the degree of chest excursion or movement:
