Sleepwalking
Sleep disorderDevelop automatic motor activitiesUnconsciouslyNo communicationDuration undetermined: 30 seconds - 30 minutesOccurs during Phase 3 (NREM)
![Page 13: Sleep](https://reader033.fdocuments.us/reader033/viewer/2022060109/55524715b4c9059a4f8b490b/html5/thumbnails/13.jpg)
Sleep Apnea
Sleep disorderPauses in breathing (apnea)Duration undetermined: few seconds – minutesThere are three forms: -Obstructive -Central -Mixed

Sleep Apnea: Obstructive
The most common sleep-disordered breathingMuscles are relaxedObstruct the airway

Sleep Apnea: Central
Brain’s respiratory control centers imbalancedNo effort to breatheNo chest movementsCompensatory Mechanism: -Blow off waste gases-Absorb Oxygen

Sleep Apnea: Mixed
Combination of:-Obstructive-Central
