Obstructive sleep apnea (OSA) is characterized by intermittent breathing during sleep.

This comes up whenever the airway becomes blocked or partially blocked as you sleep.

How is sleep apnea currently diagnosed?

The traditional method for diagnosing sleep apnea involves an overnight sleep study.

This can be conducted at home, but will often take place in a sleep clinic or hospital.

Using nocturnal polysomnography, these sleep studies measure how many times breathing is interrupted during sleep.

The results are then analyzed against the apnea-hypopnea index, to determine a potential diagnosis.

Sleep studies are accurate, but often disruptive and sometimes hard to access.

However, while these techniques are more convenient than traditional diagnostic methods, they’re not currently readily available.
