If central sleep apnea is medication-induced (e.g., opioids), reducing the dose or eventual withdrawal of the offending medication often improves CSA. The FDA has recently approved a pacemaker-like implantable device called the remedē System for adult patients with moderate to severe central sleep apnea. After a commonly performed procedure, the device stimulates a nerve in the chest (phrenic nerve) to send signals to the large muscle that controls breathing (the diaphragm). It monitors respiratory signals during sleep and helps restore normal breathing patterns. The device is silent, activates automatically during the night, and does not require the patient to wear a mask. Mechanical regulation of airflow and/or airway pressure:Treatment for central sleep apnea differs in that the device is set not at one constant optimal pressure but rather at two different settings, one for inhalation (IPAP) and for exhalation (EPAP), maintaining normal breathing rhythm by inflating the patients lungs at regular intervals whose specifics, such as the breathing rate and the duration of a single breath, can be programmed. Devices tailored to this purpose are known as BiPAP ("bilevel positive airway pressure") devices. Both CPAP and BiPAP devices can be connected to a humidifier to humidify and heat the inhaled air, thus reducing unpleasant symptoms such as a sore throat or blocked nose that can result from inhaling cold, dry air.
Sudden infant death syndrome is sometimes theorized to be attributable to sleep apnea; the recommendation, prevalent since the mid-1980s, of placing infants on their backs rather than their stomachs for sleep represents an attempt to prevent those instances of breathing cessation that are attributable to compressive obstruction. Premature infants with immature brains and reflex systems are at high risk for central sleep apnea syndrome, even if these babies are otherwise healthy. Premature babies who have the syndrome will generally outgrow it as they mature, provided that they receive careful enough monitoring and supportive care during infancy to survive. Because of premature infants propensity toward central apnea, medications that can cause respiratory drive depression are either not given to them or administered to them only under careful monitoring, with equipment for resuscitation immediately available. Such precautions are routinely taken for premature infants after general anesthesia; administration of caffeine has been found not only to aid in maintenance of respiratory function after general anaesthesia but to reduce apnea for preterm infants regardless of context. Diagnosis
A diagnosis of sleep apnea requires determination by a physician. The examination may require a study of an individual in a sleep lab, although the AAST has said a two belt IHT (In Home Test) will replace a PSG for diagnosing obstructive apnea. There, the patient will be monitored while at rest, and the periods when breathing ceases will be measured with respect to length and frequency.
