Sleep theory

Mike asked me how sleep guide could help prepare me for my boards. This was not an easy question for me. With a few exceptions I have a great understandings of the basics. I may not be quite up to par on all the ways to treat apnea, but I do understand the disorder quite well. So I got to thinking. From what I have been told the test covers a great deal of sleep theory. I have studied cause and effect mainly putting of the why. I propose that we learn it together as it will help all of us. This should not be a hard task as most of my education on this matter is coming from the internet or the library. I invite you all to participate as much or as little as you want.

I have just finished reading Dr. Dement's book "The promise of Sleep" I am currently reading this link on sleep

http://www.sleephomepages.org/sleepsyllabus/sleephome.html

I invite you all to an open discussion of both of these pieces of sleep literature. I will also be posting discussions on all 88 sleep disorders in the coming days. If there is anything in particular that anyone would like to discuss first please let me know.

However, the issue of an apnea occurring within a hypopnea (an event that could be called an apnea/hypopnea) has not yet been addressed. Most experienced sleep technicians have seen an event that could be scored as a hypopnea based on the majority of the event but contains an apnea as well. That occurs at the beginning and/or the end of the event with airflow signals that are less than an 80% reduction (typically only about a 50% reduction) in airflow. However, somewhere within the apnea/hypopnea event (beginning, middle, or end), there exists a period of 10 seconds or more of 80% to 100% airflow reduction that is great enough to be called an apnea

I believe that this event now is called an obstructive Hypopnea. You can also have central hypopneas.

Also as far as respiratory belts go most labs are moving away from piezo and going with RIP belts.

Forgive me Jeff I keep telling myself that I need a better tutorial on the equipment. I know what most of it does, but probably can only tell you the name of about 50% of it. Up until a few months ago I had these 2 pieces of equipment backwards. I am pretty sure that most labs use a pressure transducer and a thermocoupler on all if not most patients. airflow vs air pressure. This gives the tech a clear look at how a pt is breathing via their mouth and nose. Also end tidal Co2 should be monitored if a pt has a BMI over 40% or has some sort of complex apnea that might need Co2 to be measured.

For those of you that are following this post be sure to check out the collective wisdom site. carol and the sleepguide crew have put together quite a bit of great info. I know that I put up alot of links on different studies and pull facts out of text books, but I owe a ton of credit to the members on this site for pushing me along in my education.

I haven't done it yet, but I'm going to do my "homework" here. Promise. Very excited about this thread. Thanks Rock!
