I'm brand new to this board, and just got the results of my sleep study.  The doctor did not go through it as thoroughly as I would've liked, and from what I've read here, that's not uncommon.  These are the output tables (note * denotes "significant abnormalities):

Table 1.  Sleep Profile
Time at Lights Out:  22:23:17
Time at Lights On:  05:03:06
Total Recording Time (TRT):  399.8 min
Total Sleep Period Time (TSP):  381.9 min
Total Sleep Time (TST):  361.5 min
Sleep Latency:  17.9 min
Number of REM Periods:  3
Number of Stage Shifts:  67
Number of Awakenings:  16
Sleep Efficiency:  90.4%

Table 2.  Sleep Stages
Stage     Time (min)     %TST     Latency (min)
Wake      18.9              -            -
1            10.5              2.9         0.0
2            203.5            56.3       3.5
3            90.0              24.9       69.5
4            0.0                0.0*       NA
REM        57.5              15.9       105.5

Table 3.  Respiration & EKG
Apneas + Hypopneas:  74
Apnea + Hypopnea/hr:  12.3*
REM events/hr:  40.7*
Non-REM events/hr:  6.9
% Sleep Time Supine:  8.3
Snoring:  Loud
EKG Arrhythmia:  No

Table 4.  Oxygen Saturation
Parameter                Awake          Non-REM           REM
Mean SaO2%:           96.5             96.1                 95.6
Min SaO2%:              92.2             90.1                 84.4*
Max SaO2%:             99.0             98.5                 99.0

Table 5.  Periodic Limb Movements During Sleep (PLMS) & Arousal Data
PLM/hr:   Total:  1.2
              Non-REM:  1.4
              REM:  0.0
PLM Arousals/hr:   Total:  1.2
                           Non-REM:  1.4
                           REM:  0.0
Spontaneous Arousals/hr:  Total:  8.6
                                       Non-REM:  9.7
                                       REM: 3.1
Respiratory Arousals/hr:  Total:  10.3*
                                     Non-REM:  6.7
                                     REM:  29.2*
Periodic Breathing:  No
Bruxism (Total Episodes):  No

The interpretation said:
- evidence of primarily REM-related obstructive apnea-hypopnea and continuous loud snoring, associated with frequent movement arousals and mild REM-related arterial oxygen desaturation

I would appreciate any, and all, help.  The doctor said I wasn't very severe, and that a CPAP is my choice.  I'm just so exhausted and drowsy that I'm buying one just to be on the safe side.

...I forgot to add that night was not totally representative of a normal night for me.  I was extra tired having stayed up later than normal the previous night.  Thanks again for any help.

Hi TG:
Sleepydave's handy guide to sleep study interpretation considers 3 factors:  AHI, lowest oxygen saturation and level of daytime sleepiness.  Even though your AHI rates you as mild OSA, that low SaO2 and level of sleepiness makes it NOT a choice.  You're doing the right thing getting a CPAP.

Thanks Sleepydave!  I'm glad I was persistent; the doctor seemed to be concerned with me paying the deductable for the machine (I have benefits from work but it would cost me a small amount out-of-pocket).  She said she didn't want me to pay for it and it not working for me.

What about the 0% of Stage 4 sleep?  Is this concerning at all?  I read up on sleep stages on here and other sites and I hear it's the most deep sleep...

Hi TG!
I assume you'll be going for a CPAP titration, then you'll know if CPAP works in ways that you will see and feel, and perhaps things you won't notice.
The CPAP should get rid of that low oxygen saturation.
Your sleepiness should improve.
But even mild OSA can create all the long-term health problems one usually relates only to the more severe forms of the entity.  Shoot, even UARS (no real respiratory events, just narrowing of the airway creating arousals) can create problems such as high blood pressure.
The Medicare criteria, which most insurers follow, allow payment for CPAP units if the AHI is between 5 and 14 when there's excessive daytime sleepiness.  That an insurer will pay their portion certainly suggests they realize there's long-term value in the therapy.
Deep sleep, delta sleep, slow wave sleep and Stage 3/4 are all synonyms for that restorative sleep.  Both Stages 3 and 4 are included in the calculation.  So 24.9% is a hefty amount of SWS.  SWS decreases as a function of age, and lots of Stage 4 tends only to occur only when we're young.

Young?  I turned 30 recently...

I mean like, 8.

I haven't been like 8 for ages.  This is a great and useful forum!  Thanks for all your help...
