What is obstructive sleep apnea?
Obstructive sleep apnea (OSA) is a common sleep disorder affecting between 9 and 38% of adults. It is characterized by breathing pauses during sleep, which can lead to intermittent hypoxia (lack of oxygen) and sleep fragmentation.
The importance of diaphragmatic function
The diaphragm plays a crucial role in breathing, accounting for 60 to 80% of the ventilatory effort. However, functional changes in the diaphragm in patients with OSA have not been sufficiently studied so far.
The study results
This study included 62 patients evaluated for suspected OSA. Researchers used ultrasonography to measure diaphragmatic function and found a correlation between left diaphragmatic excursion and the severity of OSA. While ultrasonography showed potential to help assess the risk of OSA, further validations are needed.
What does this mean for patients?
For patients affected by obstructive sleep apnea, these results suggest that ultrasonography could be a useful tool for assessing diaphragmatic function. However, it is important to note that these results need to be confirmed by other studies before they can be used in clinical practice.
