Sleep disordered breathing (SDB) describes a group of disorders characterised by:
An apnea is when a patient stops breathing for 10 seconds or more, and they wake up just enough to take a breath.
A hypopnea is when a patient doesn't stop breathing, but the patient's breathing becomes shallow (i.e., at least a 30% decrease in airflow) for 10 seconds or more, with an associated oxygen desaturation or arousal.
Either way, sleep disordered breathing disrupts the patient's sleep pattern, night after night, which not only makes the patient tired and exhausted the next day, but may also put excessive strain on the their nervous system and major organs.
The first sign of a sleep disorder is snoring, even though many patients won’t identify that as a sign of something more serious. There are other common symptoms too.
There are three main types of sleep-disordered breathing which are manifested in sleep apnea. Discovering the specific differences between them can help you recognise how best to treat your patients.
Adherence to therapy can be the biggest challenge for patients with sleep apnea. Comfortable equipment, proper replacement, follow-up and education are critical to helping patients adapt to and stay on therapy.
