Changes

You now have a referral from your Doctor for a sleep study. What do you do now? First the normal speed all this occurs at. I’ll put it Naval terms, Flank Speed means fast, get from point A to point b as fast as you can. This is where you want to be. Unfortunately , the most common speed things move at is, again in Naval terms, DEAD SLOW. You need to expedite these steps so you can get them done and out of the way quickly. It is not uncommon for each step to take 1-2 MONTHS!!!

*In Lab Initial Study: Usually a Level 1 sleep study, IMHO the better choice, A study performed without a mask or xPAP machine to establish you base level of Apnea. For this you will be connected every which way you can think of, ok not every way but . . (You will need to shampoo your hair after this study)*In Lab Split Study: Usually a Level 1 sleep study, Actually two sleep studies in one night, At least two hours (per Medicare) without a mask followed by a titration study with a mask to determine your treatment settings. Sometimes there is not enough time left to perform the titration thus requiring a second night in the sleep lab.(You will need to shampoo your hair after this study)*Titration Study: Usually a Level 1 sleep study, a study with a mask to determine your treatment settings.(You will need to shampoo your hair after this study)*At HomeSleep Study: **Level 2 Sleep Study: (May be either an In-Lab or Home Sleep Study) A level 2 sleep study (also called Polysomnography). In addition to monitoring your breathing, oxygen levels, and heart rate, a level 2 sleep study also monitors brain and muscle activity. This added monitoring means a level 2 sleep study is a more sensitive test than a level 3 sleep test and can monitor your leg and body movement, detect periodic limb movement disorder (PLMD), and provide a more in-depth analysis on the overall quality and length of your sleep. Curently http: TBD//axgsleepdiagnostics.com/ is offering a Type 2 unattended at home kit.**Level 3 Sleep Study: In a level 3 sleep study, you use kit at home that records your breathing activity, oxygen levels, and heart rate throughout the course of the night. Currently, WatchPat is the common one.

Polysomnography is a comprehensive recording of the biophysiological changes that occur during sleep. It is usually performed at night, when most people sleep, though some labs can accommodate shift workers and people with circadian rhythm sleep disorders and do the test at other times of day. The PSG monitors many body functions including brain (EEG), eye movements (EOG), muscle activity or skeletal muscle activation (EMG) and heart rhythm (ECG) during sleep. After the identification of the sleep disorder sleep apnea in the 1970s, the breathing functions respiratory airflow and respiratory effort indicators were added along with peripheral pulse oximetry.
