Once the swelling resolves and the palate becomes tightened by postoperative scarring, however, the full benefit of the surgery may be noticed. A person with sleep apnea undergoing any medical treatment must make sure their doctor and anesthetist are informed about the sleep apnea. Alternative and emergency procedures may be necessary to maintain the airway of sleep apnea patients. Other
Neurostimulation
Diaphragm pacing, which involves the rhythmic application of electrical impulses to the diaphragm, has been used to treat central sleep apnea.In April 2014, the U.S. Food and Drug Administration granted pre-market approval for use of an upper airway stimulation system in people who cannot use a continuous positive airway pressure device. The Inspire Upper Airway Stimulation system senses respiration and applies mild electrical stimulation during inspiration, which pushes the tongue slightly forward to open the airway. Medications
There is currently insufficient evidence to recommend any medication for OSA. This may result in part because people with sleep apnea have tended to be treated as a single group in clinical trials. Identifying specific physiological factors underlying sleep apnea makes it possible to test drugs specific to those causal factors: airway narrowing, impaired muscle activity, low arousal threshold for waking, and unstable breathing control. Those who experience low waking thresholds may benefit from eszopiclone, a sedative typically used to treat insomnia.
Stroke is associated with obstructive sleep apnea.Obstructive sleep apnea is associated with problems in daytime functioning, such as daytime sleepiness, motor vehicle crashes, psychological problems, decreased cognitive functioning, and reduced quality of life. Other associated problems include cerebrovascular diseases (hypertension, coronary artery disease, and stroke) and diabetes. These problems could be, at least in part, caused by risk factors of OSA. Central sleep apnea
In pure central sleep apnea or Cheyne–Stokes respiration, the brains respiratory control centers are imbalanced during sleep. Blood levels of carbon dioxide, and the neurological feedback mechanism that monitors them, do not react quickly enough to maintain an even respiratory rate, with the entire system cycling between apnea and tachypnea, even during wakefulness. The sleeper stops breathing and then starts again. There is no effort made to breathe during the pause in breathing: there are no chest movements and no struggling. After the episode of apnea, breathing may be faster (tachypnea) for a period of time, a compensatory mechanism to blow off retained waste gases and absorb more oxygen. While sleeping, a normal individual is "at rest" as far as cardiovascular workload is concerned. Breathing is regular in a healthy person during sleep, and oxygen levels and carbon dioxide levels in the bloodstream stay fairly constant. Any sudden drop in oxygen or excess of carbon dioxide (even if tiny) strongly stimulates the brains respiratory centers to breathe. In any person, hypoxia and hypercapnia have certain common effects on the body.
