Sleep Study Questions
I keep trying to decipher my sleep study results with ones listed on this board and of course, some google fu. My home sleep study only had the oximeter and an electrode on my throat, along with a wristwatch connecting it all together. No chest straps or anything else?
Do these results indicate I had any central apneas?
IMPRESSIONS
- Mild Obstructive Sleep apnea(OSA) with an AHI of 7.4/hr and REM AHI of 14/hr
- Patient snored 2.5% during the sleep.
RECOMMENDATIONS
- Oral appliance may be considered.
- Avoid alcohol, sedatives and other CNS depressants that may worsen sleep apnea and disrupt normal sleep architecture.
- Sleep hygiene and medications may be reviewed to assess factors that may improve sleep quality.
- Weight management and regular exercise should be initiated or continued.
- Discuss the results of the sleep study with the referring provider.
- Thank you for utlilizing the WellSpan Sleep Center.
- Portable studies present limited sleep data compared to that of an in-laboratory polysomnogram and may underestimate the severity of sleep-disordered breathing. This study was scored and interpreted according to American Academy of Sleep Medicine guidelines. This study was deemed to be technically adequate based on accepted standards unless noted specifically above.
- Clinical correlation is recommended for all patients undergoing home sleep testing. Caution is recommended with driving or during other activities requiring alertness for safety.
MONITORING
The WatchPAT device is worn on the wrist and is utilizing a plethysmographic based fingermounted probe, to measure the PAT (Peripheral Arterial Tone) signal. The PAT signal is a measurement of the pulsatile volume changes in the fingertip arteries which reflects the relative state of the arterial vasomotor activity, and thus indirectly the level of sympathetic activation. Peripheral arterial vasoconstriction, which mirrors sympathetic activation, is shown as attenuation in the PAT signal amplitude.
AMBULATORY SLEEP STUDY REPORT
Date of study: 11/12/2019
STUDY DATA:
Ambulatory Watch PAT Sleep Study:
Total Study Time: 10.3 hours
Study Start Time: 21:11:35 PM
Study Stop Time: 07:31:39 AM
Sleep Time: 539.6 minutes
Sleep Time REM %:
Respiratory Indices:
pRDI4%: 11.1 (REM: 18; NREM: 10.2)
pAHI4%: (REM: 14; NREM: 6.6)
Total pAHI4%: 7.4
Total pAHIC4%: 0
pRDI4% supine: 15.1
pAHI4% supine: 9.3
Position:
Supine Time: 3 hrs. 28 min.
Non-Supine Time: 5 hrs. 31 min.
Non-Supine AHi: 6.2
Oxygen Saturation:
Oxygen Desaturation Events (ODI4%): 5.4
ODI4% (Supine): 7.3
Saturation <90%: 0%
Saturation <=88%: 0%
Saturation <80%: 0%
Saturation < 70%: 0%
PULSE STATISTICS (beats per minutes)
Mean: 72; Min: 36; Max 114
SUMMARY
This was a WatchPAT study. pAHI and pRDI events were scored utilizing 4% oxygen desaturations. The patient received written and verbal instructions on use of this device, in addition they were given access to an instructional video and a phone number to call with questions or problems
Study appears technically adequate.
Summary of respiratory data:
pAHI4%: 7.4; ODI4%: 5.4; T90%:0.2%; Min Saturation: 88%
EPWORTH NA/24
