In central sleep apnea disorder the patients breathe intermittently. It stops and restarts during sleeping.  This happens because the brain fails to send signals to the muscles that are responsible for controlling the breathing. This different from obstructive sleep apnea in which the sleep is disrupted because of the obstruction in the upper airway. According to sleep apnea doctor, heart attack and stroke are two other conditions that can cause central sleep apnea.

Common symptoms related to sleep apnea are listed below.

  • Abnormal break and restart in breathing during sleeping
  • Sudden awakening with shortness of breath
  • Shortness of breath which is relieved when you sit up
  • Difficulty in maintaining sleep
  • Excessive sleeping tendency during day time
  • Night chest pain
  • Mood changing
  • Finding it difficult to concentrate
  • Snoring
  • Morning headache


Causes of sleep disorder

Central sleep apnea can be caused by a number of reasons. Some of them are detailed below:

  1. Cheyne-stokes breathing: Congestive heart failure is the reason for this type of sleep apnea. Gradual increase followed by decrease in the air flow and breathing effort is the characteristic of this type of sleep apnea.
  2. Dug-induced apnea: Some drugs like opioids or codeline sulfate can cause the breathing to become irregular or can lead to temporary stopping of breathing completely.
  3. Periodic breathing at high altitude:  When the patient is at high altitude breathing pattern of Cheyne-stokes can occur. The reduced availability of oxygen at higher altitude is the reason for this.
  4. Complex sleep apnea: Some patients develop central sleep apnea when they undergo CPAP  treatment related to sleep apnea. This is termed as complex because it is  a combination of obstructive sleep apnea and central sleep apnea.


Risk factors

The common risk factors suggested by sleep apnea doctor are given below.

Sex:  In studies conducted in a sleep center, It is found that males are at a greater risk of developing sleep apnea than women.

Age: Older people are more prone to sleep apnea than young people.  sleep apnea doctor  opines that adults over 65 are more prone to sleep apnea.

Heart disorders: People who suffer from arterial fibrillation or who are likely to have heart failure are at greater risk of sleep apnea.

Brain tumor, stroke etc: People who are having brain tumor or are prone to stroke are at greater risk of central sleep apnea.


Some of the most common treatment procedures available at a sleep center are discussed below.

Addressing associated problems:  Most central sleep apnea is caused as a result of other disorders. Treatment for such disorders has often found to be useful in relieving the symptoms of sleep apnea.

Reduced use of opioid medications: Your sleep apnea doctor will reduce the intake of opioid medicines, if he thinks it has some effect in your sleep apnea

CPAP: In this treatment the patient in a sleep center is asked to wear a mask while sleeping.  The mask is connected to a small pump that supplies pressurized air for your upper airway. This procedure prevents closing of upper airway thereby preventing sleep apnea.

ASV: Adaptive servo-ventilation: When CPAP is not able to be utilized satisfactorily in controlling sleep apnea, sleep apnea doctor germantown suggests this procedure.  In this method also pressurized air is supplied to sleep apnea patient. Amount of pressure is adjustable in this case.

BPAP: This is another method of supplying pressurized air for sleep apnea patients.

Medications: Medications like acetazoamide, theophylline etc also has been found to be very useful.
