While scoring a polysomnogram of a 30 year old female, you notice central apneas during the transition from wake to sleep. Once asleep, the patient's apneas subside. What are these episodes?

A calculation of total sleep time divided by total bed time. Normal sleep efficeincy is >90%. A sleep efficiency of <90% might indicate a sleep problem such as insomnia or apnea.

These events are called onset or transitional apneas.

Not test questions--
Okay Rock on the list of questions it states that it is total sleep time/total bed time X 60. So I am totally confused == if you have less than 90 percent sleep effiency that is normal but if you have a greater than 90 percent sleep efficiency that means you have insomnia or apnea?
It would seem that it would be the other way around. If you had less than 90 percent it would indicate a problem. Okay let's say that you go to bed and total bed time is 480 minutes and you sleep for a total of 430 minutes wouldn't that mean you may have insomnia instead of good sleep?
What is insomnia and what percent would it have to be considered insomnia? Isn't insomnia not being able to go to sleep? What about if you fell asleep and then woke after a couple of hours and then couldn't go back to sleep for an hour or more? What is that called?

total sleep time/total bed time X 60
would that be total sleep time divided by total bed time times 60

When I mess up I do it well. Sleep efficiency is sleep time divided by bed time x 60. Normal sleep effiency is greater than 90%. A sleep effieciency of less than 90% may indicate a sleep problem such as insomnia or apnea.
Sorry for confusing everyone.
I got my alligators mixed up ><.

Thanks for the reply...
I've had MSLT to find out if I have Narcolepsy. Doctors say I have it because of the blood tests.
Epworth scale - 20
Naps: sleep latency
#1 - 1.2 min
#2 - 1.4 minutes
#3- 1.1 minutes
#4- 1.3 minutes
Lauren Major said:I wonder though, I had a blood test done that came back positive for Narcolepsy, but my MSLT came back negative. My naps were all <2 but no REMs.
I'd like to know how accurate that is. I was sure that I was dreaming, or at one time even felt as though I was talking myself into going to sleep the whole time, when in fact, I was sleeping. (<2).

you should put numbers or letters on them

I am positive for HLA, no cataplexy, and kick the heck out of my bed partner. I wake up exausted and my blankets all over the place. I'm thinking that the name, Narcolepst or Excessive Sleep, doesn't matter. I just wish that there was a doctor in NV that understood and knew how to help.

I believe REM Behavior Disorder (RBD) to be the opposite of Narcolepsy. Patients with REM disorder from not having the benefit of sleep paralysis. This disorder allows its victims to act out their dreams while making havoc for themsleves, their bed partners, or their surroundings.
Narcolepsy in a nut shell is instant sleep paralysis, or stage REM at sleep onset. This can be triggered by causing an extreme emotional situation such as laughter or anger in patients with this disorder (Narcolepsy with cataplexy). Vivid dreams can aslo occur during these events. these dreams can include the current surroundings and have been tied to the current UFO phenomena (Narcolepsy with hypnagogic hallucinations). Some argue that narcolepsy without cataplexy or hypnogogic hallucinations is just excessive sleepiness.
