Central sleep apnea is a disorder that causes individuals to have one or more pauses in breathing or shallow breaths during sleep. Breathing pauses can last from a few seconds to minutes. Central sleep apnea occurs when the brain fails to send signals to the diaphragm to breathe, causing an individual to stop breathing during sleep for a period of 10 seconds or more before restarting again. According to the National Institute of Health’s National Center on Sleep Disorders Research, central sleep apnea can lead to poor sleep quality and may result in serious health issues, including an increased risk for high blood pressure, heart attack, heart failure, stroke, obesity, and diabetes. Common treatment options for moderate to severe sleep apnea include medication, positive airway pressure devices (e.g., continuous positive airway pressure machine), or surgery.
