What is the difference between obstructive sleep apnea (OSA) and central sleep apnea (CSA)?

By BabySleepAdmin 3 years ago

What is the difference between obstructive sleep apnea (OSA) and central sleep apnea (CSA)?  

Obstructive sleep apnea (OSA) usually occurs in children due to large tonsils and large adenoids. These cause intermittent complete or partial obstruction (blockage) of the upper airway during sleep. The child usually snores at some stage of sleep most nights and parents might notice that their child has pauses in breathing followed by a gasp during sleep. The child tries to breathe but there is little or no airflow through the nose and mouth.

Central sleep apnea (CSA) occurs when the child seems to forget to breathe. There is no effort to breathe and therefore no airflow. In CSA, the brain typically does not send a message to the body to breathe. These infants are usually quiet in their breathing. CSA is common in infants especially if they are premature.

Additionally, some babies have something called periodic breathing, where there are repetitive pauses in breathing followed by increasing efforts followed by yet another pause. This pattern can repeat for many minutes during sleep. Babies (and others) living in high altitudes often have periodic breathing (PB). With maturity, PB usually self-resolves. Sometimes supplemental oxygen is needed.
