Central Sleep Apnea

Signs and Symptoms

Intermittent pauses in breathing is the main symptom of central sleep apnea, but there are others, including:

• Fatigue
• Trouble focusing
• Waking during the night
• Headaches
• Lack of energy

Unlike obstructive sleep apnea, central sleep apnea rarely causes snoring.

Risk Factors:

• Heart disorder like irregular heartbeats (Atrial Fibrillation) or CHF
• Stroke, brain tumor or a structural brainstem lesion
• Opioid use
• CPAP
• High altitude
• Age (65+)
• Gender (Males are more likely to develop CSA)

Testing and Treatment

To test for central sleep apnea, your physician may refer you to a specialist to conduct a sleep apnea test. A polysomnogram, or sleep study, is a comprehensive test that transmits and records specific physical activities while you sleep, such as your heart rate, brain activity, eye movement and oxygen levels, through a series of electronic sensors placed on your legs, head and chest.

If you are diagnosed with CSA, there are a variety of potential treatments your doctor may recommend. First and foremost, it’s helpful to maintain a healthy lifestyle. This means keeping fit, avoiding alcohol and other depressants and getting plenty of rest.

To help keep your airway functioning as you sleep, your doctor may recommend a PAP machine. This device forces air through your nose and/or mouth to ensure you get enough oxygen as you sleep. Other treatments include certain medications can also be prescribed or an implantable device to help stimulate breathing.
