Mixed Sleep Apnea
As the name suggests, mixed sleep apnea is a combination of central sleep apnea and obstructive sleep apnea. Generally, there is no signal from the brain to breathe at the beginning of the apnea, resulting in no effort and no airflow. Then, in the midst of the central apnea, the brain kicks in and respiratory effort starts, but by this time the airway is obstructed due to relaxation of the soft tissue in the airway. The result is obstructive sleep apnea.
Mixed sleep apnea is generally treated with continuous positive airway pressure (CPAP).
