What Are The Signs And Symptoms Of Sleep Apnea?
ABG
Detailed Answer:
Hello and thank you for asking in HCM
I can understand your concern
Sleep study (Polysomnography) is mainly for detection of sleep apnea however we can get from it some information about hypoventilation status of the lungs too.
In my opinion Arterial blood gases test and Difussion lung capacity test (ABG and Dlco) may be more helpful for evaluation of lung ventilation status.
The most important function of the lungs is gas exchange which means that hypoventilation itself leads to hypoxemia.
Spirometry test can help too (if you can do it)
Nevertheless i don't think that the first test may have missed something don't worry
Please discuss with your doctor for the above.
Take care and feel free to ask me again
