Document Summary
Learn about the diagnosis and treatment, and impact on waking function in apnea, and plm/rls, and narcolepsy. Describe the signs and symptoms, and nature of sleep apnea (osa and csa). Compare the current treatment options for apnea. Describe the clinical features, epidemiology, and diagnosis of. Apnea ((cid:862)want of breath(cid:863)): a breathing disorder characterized by brief interruptions of breathing during sleep. Associated completely with sleep, not with asthma etc. Central sleep apnea (csa): brain fails to send signals to breathing muscles to initiate respirations. Neurons in brainstem not functioning, don"t signal the rest of the brain to carry out breathing. These periods of not breathing can be quite long. Obstructive sleep apnea (osa): ai(cid:396) ca(cid:374)(cid:374)ot flo(cid:449) i(cid:374) o(cid:396) out of pe(cid:396)so(cid:374)"s (cid:374)ose o(cid:396) (cid:373)outh, although efforts to breathe continue. More prevalent, commonly associated with obesity (more fatty tissue leads to this sagging more into the airway and blocking it) Apnea events can be quite frequent (20-60 times in the night).
