If you have ever experienced severe pain, whether due to injury or illness, your doctor may have given you a prescription for opioids.  Opioids can be very successful at treating severe pain, but they do come with side effects. One of those side effects is Opioid Induced Central Sleep Apnea, or CSA. If you are suffering from an opioid related sleep disorder, some of the symptoms you may be experiencing include prolonged obstructive hypoventilation, obstructive apnea and hypopnea, and a mixed pattern of sleep disordered breathing. However, it’s important to note that these side effects are most commonly associated with long-term use of opioids. 
Although these symptoms do not tend to resolve on their own, and optimal treatment is unclear, Adaptive Servoventilation (ASV) treatment study data has shown improvement in certain patients.  Adaptive Servoventilation, or ASV, is a non-invasive airway pressure device. This device works by tracking airflow in a three to four minute window, continuously throughout the night, stabilizing the respiratory drive by providing pressure support and adjusting respiratory parameters to maintain 90% of the calculated peak flow.
Hypnus company has launched its PAP device model SV825W specifically to treat patients with this kind of pathologies. More information about Hypnus products www.mrsleepus.com/
