Brief summary

Detailed description

Obstructive sleep apnea (OSA) is associated with altered respiratory mechanics, including diaphragmatic function. Ultrasonography provides a non-invasive tool to assess diaphragmatic structure and performance, which may correlate with OSA severity. The aim of the study is to evaluate diaphragmatic function in OSA patients using ultrasonography and to investigate its relationship with OSA severity and sleep-related parameters.
