Key facts about obstructive sleep apnoea
Obstructive sleep apnoea (OSA) is the most common form of sleep-disordered breathing (SDB), affecting more than 3 in 10 men and nearly 1 in 5 women.1
Patients who suffer from OSA often experience partial or full upper airway collapse during sleep, leading to either:
- An apnoea, which is the cessation of airflow for 10 seconds or more.
- A hypopnoea, which is a decrease in airflow lasting for more than 10 seconds, with a reduction of 30% in airflow and at least 3% oxygen desaturation from baseline, or an arousal from sleep.
If your patients have sleep-disordered breathing, they are most likely suffering from disruptive sleep, daytime fatigue and a reduced quality of life.
Symptoms of OSA
One of the most recognisable symptoms of OSA is snoring, even though many patients ignore this sign or fail to recognise it as a symptom of a more serious condition.
Other symptoms of SDB may include:
- excessive daytime sleepiness (EDS)
- poor concentration
- morning headaches
- depressed mood
- night sweats
- weight gain
- sexual dysfunction
If your patients present with any of these symptoms, it’s important to talk to them about SDB and recommend a sleep test. When left untreated, patients with SDB have an increased risk of developing serious chronic diseases such as cardiovascular disease,2,3 and type 2 diabetes.4
Helping patients stay on therapy
Adherence to therapy can be the biggest challenge for patients with sleep apnoea. At ResMed, we believe that compliance and efficacy are directly related to comfort. And to maximise comfort, we’ve designed the Narval CCTM* mandibular repositioning device (MRD) to be one of the smallest and lightest oral appliances available on the market.
MRDs have gained recognition over the last decade as an effective solution to snoring,5 as well as a clinically-proven alternative to CPAP treatment in cases of mild to moderate OSA.6,7,8
Other types of SDB
Central sleep apnoea (CSA) is less common than OSA.9 Unlike OSA patients who have partially or fully blocked upper airways that restrict breathing, patients with CSA have a central nervous system disorder. This means either the breathing centre in the brain fails to trigger breathing, or the signal to inhale is not transmitted properly to the rest of the patient’s body.
Mixed sleep apnoea is a combination of OSA and CSA. While mixed sleep apnoea is more common than CSA, it still is less prevalent than OSA.10
