New OSA patient

Completed a sleep study on 8/27/25. I am copying some of the data collected during that study. I began the study around 8:15 pm and it looks like it ended around 12:45am when they came in and said I needed to put on a CPAC mask due to breathing issues. Current status is my Doctor has forwarded a Rx to a DME provider for the necessary items I will need. He requested an Auto-Titrating CPAP machine and Fisher and Paykel Evora Full-Face Mask (Small/Medium Cushion). Any advice regarding these items would be appreciated. My energy level for the past year or more has been zero. I can sleep 11 hours and wake more tired then when I went to bed. I am hoping/praying that this disorder might be the reason and if I can survive the CPAC experience my energy level will improve !?!?

Patient Information: The patient is a 78 year old Undefined who presents with symptoms of loud snoring,
exacerbation of sinonasal congestion with copious secretions associated with sleep, sleep–related
overheating/perspiration, restless sleep, poorly–restorative sleep and excessive daytime sleepiness. An overnight
polysomnogram is being performed to evaluate for sleep disordered breathing.

Diagnostic Portion
Sleep Architecture:
Polysomnographic recording began at 20:19:39 and ended at 00:43:09. Total recording time was 263.5 minutes and
total sleep time (TST) was 203.0 minutes. The sleep efficiency was 77.0%. Sleep latency was 13.0 minutes. Wake
after sleep onset (WASO) was 47.5 minutes. There were 184 episodes of arousal for an arousal index of 54.4 per
hour. The patient spent 56.5 minutes in the supine position (27.8% of TST) and 146.5 minutes in non-supine sleep
(72.2% of TST). Sleep stages: Stage N1 was 22.5 minutes or 11.1% of TST. Stage N2 was 175.5 minutes or 86.5%
of TST. Stage N3 was 5.0 minutes or 2.5% of TST. Stage REM was 0.0 minutes or 0.0% of TST.
Respiratory Parameters:
The overall apnea/hypopnea index (AHI) using AASM scoring criteria was 44.0 per hour. The overall AHI using ≥ 4%
desaturation rule for hypopneas was 15.7. The obstructive AHI was 44.0. The central apnea index was 0.0. There
were 13 total apneas (13 obstructive, 0 mixed, & 0 central apneas), 136 hypopneas, and 0 respiratory event related
arousals (RERAs). The longest apnea was 25 seconds and the longest hypopnea was 60 seconds. The average
duration for obstructive apneas was 16 seconds and for obstructive hypopneas was 26 seconds. The REM AHI was
0.0 while NREM AHI was 44.0. The supine AHI was 54.2 while non-supine AHI was 40.1. The final respiratory
disturbance index (AHI + RERAs) was 44.0. Cheyne-Stokes breathing was not appreciated. Moderate to loud,
intermittent snoring was observed.
Oxygen Parameters:
The average oxyhemoglobin saturation during wake was 93%. The average during sleep was 94%, reaching a nadir
value of 88%. The patient spent 2.5 minutes with oxygen saturations < 90 % and 0.2 minutes with saturations < 88
%. The nadir saturation associated with respiratory events include: 88% for obstructive apneas and 88% for
hypopneas.
Sleep Related Movements:
The left and right anterior tibialis EMG recording revealed a total of 149 periodic limb movements during sleep,
providing a periodic limb movement (PLM) index of 44.0; of those, 23 were associated with EEG arousals, providing a
PLM-arousal index of 6.8.
Cardiovascular Parameters:
During sleep, the mean heart rate was 78 beat per minute (bpm) with a minimum of 68 bpm. The highest heart rate
throughout the recording was 111 bpm. No cardiac arrhythmias were noted on the limited electrocardiogram.


Impression:
1. This study confirms severe, supine-predominant obstructive sleep apnea (OSA) with an overall AHI of 44.0
(supine AHI: 59), associated with hypoxemia (with a nadir of 88%), and moderate - severe sleep
fragmentation.
2. A CPAP setting of 13 cm H2O was effective at correcting the patient’s sleep-disordered breathing and
improving the sleep architecture.

Recommendations:
1. CPAP at 13 cm H2O.
a. Mask: Fisher and Paykel Evora Full-Face Mask (Small/Medium Cushion)
b. Heated Humidification Setting: 2.
c. Pressure Relief Setting: 0.

I believe that the information you provided indicates that there is a high likelihood that you will benefit greatly from PAP, especially if you use it for all sleep and at the treatment-pressure settings that turn out to be best for you over time.

He requested an Auto-Titrating CPAP

INSIST on a ResMed AirSense 10 AutoSet or ResMed AirSense 11 AutoSet. Don't accept any other brand. Your prescription is consistent with either of these machines.

Full-Face Mask (FFM)

FFM is an indication that you breathed through your mouth during the sleep study.

Use this forum to help you resolve any issues and to help you optimize your CPAP process, including the machine settings.

Much better days are ahead for you!

Thank you for your response. I have an appointment tomorrow and they said I will be receiving the AirSense 11 you recommended.

One more question, can I use a UV Sanitizer and dryer to clean my CPAP equipment ? I have a Papablic sanitizer. Thanks

This is being ridiculously careful, but make sure it is an AutoSet. You can see here ResMed makes three different models of the 11 - https://www.resmed.com/en-us/products/c ... rsense-11/

You can, but I don't see the need for it. I've been using a CPAP for nearly 15 years. The only cleaning I have ever done is wiping down the mask with an alcohol wipe each morning and occasionally dusting the outside of the machine.

Well i spent my 1st night sleeping with my new AirSense 11 Autoset and ResMed AirFit F40 mask last night. Resmed myAir score: 95 Usage: 10:04 Mask seal: Good Events/hr 3.3 Mask off 9. The main issue I had was a very sore lower nose. I have a deviated septum and think the cushion is to tight on the underside of one side of my nose because of that. Easy fix i hope.
