Document Summary
Sleep apnea is a condition in which the patient has episodes with no breathing for periods of 10 seconds or longer. Central apnea that is due to the loss of ventilation effort by the patient.

Mixed a mixture or obstructive and central sleep apnea. Sleep apnea is often associated with daytime sleepiness and insomnia at night.
