There are several variants:

Continuous positive airway pressure (CPAP) is effective for both moderate and severe disease. It is the most common treatment for obstructive sleep apnea. Variable positive airway pressure (VPAP) (also known as bilevel (BiPAP or BPAP)) uses an electronic circuit to monitor the patients breathing and provides two different pressures, a higher one during inhalation and a lower pressure during exhalation. This system is more expensive and is sometimes used with patients who have other coexisting respiratory problems or who find breathing out against an increased pressure to be uncomfortable or disruptive to their sleep. Nasal EPAP, which is a bandage-like device placed over the nostrils that utilizes a persons own breathing to create positive airway pressure to prevent obstructed breathing. Automatic positive airway pressure, also known as "Auto CPAP", incorporates pressure sensors and monitors the persons breathing. A 5% reduction in weight among those with moderate to severe OSA may decrease symptoms similarly to CPAP.Encouraging people with moderate to severe OSA to use CPAP devices can be challenging as their use often requires a behavioural change in sleeping habits. 8% of people who use CPAP devices stop using them after the first night, and 50% of people with moderate to severe OSA stop using their devices in the first year. Educational initiatives and supportive interventions to help improve compliance with CPAP therapy have been shown to improve the length of time people who need CPAP therapy use their devices.Oral appliances or splints are often preferred but may not be as effective as CPAP.
And the risk for EDS is even increased when OSA is associated with obesity.Due to all the consequences and symptoms it generates, OSA in children lead to a significant decrease in the quality of life, the decrease being even higher when obesity is present. The quality of life can however be improved with the treatment of OSA. SBD have also been linked to a higher rate of internalizing disorders such as anxiety and depression. Indeed, depressive symptoms have shown to be higher in children with OSA, especially in males. Once again, the severity of depressive symptoms is positively correlated with the severity of the SBD. It also interacts with obesity as obese children have higher risk to show depressive symptoms and obesity can cause OSA. The link can also go the other way around with the depression inducing obesity (due to overeating) which worsens the OSA. Adenotonsillectomy can decrease the intensity of the depressive symptoms.Other consequences of a disturbed sleep in children with OSA comprise anhedonia increased fatigue and decreased interest in daily activities, which in turn can affect the childs social relationships. In adults
While there are some similarities between adults and children, OSA does not have the same consequences in both populations. Examples of similarities are the snoring – which is the most common complaint in both pediatric OSA and OSA in adults – variability of blood pressure and cardiovascular morbidities.
