Objective:
To explore the correlation between childhood obstructive sleep apnea-hypopnea syndrome and tympanogram.
Method:
A prospective clinical study was carried out. Polysomnography and tympanogram were analyzed in 72 cases.
Result:
Among the 144 ears 37 ears had type C or B tympanogram. There was no correlation between tympanogram and LSaO2. It was found correlation between tympanogram and AHI (P < 0.05).
Conclusion:
Hypoxemia may affect middle-ear function. It was necessary to do the examination of acoustic impedance routinely in children with moderate and severe OSAHS.

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:

Breath Sounds
Breath sounds are categorized into vesicular, bronchovesicular, and bronchial.
