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

Please note that I was extra tired the night I did the sleep study, having stayed up later than normal the night before.  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.
