Lindanhotair Treatment review

Lindanhotair Treatment review
I was referred for a home sleep study in August, 2017.  I was prescribed a Philips Dreamstation Auto CPAP. I, like a lot of people new to this forum, was unaware of this forum, Sleepyhead, or OSCAR and it was in July when I saw that the Auto CPAP was not doing a lot for central or complex apnea.  It responded to central events with pressure pulses, which very occasionally triggered breathing, but not enough to be useful.  I am posting a copy of my sleep study for background, with plain text followed by  graphics.

I obtained a DS1 bilevel ASV which I defoamed.  I have been experiencing mixed results on the AHI, running between 2 and 9, with the higher reported numbers from hypopneas. My oxygen saturation has stayed high, as does my minute vent and tidal volume.  I will post some examples of high and low number charts in additional posts for possible suggestions and analysis.

POLYSOMNOGRAPHY
SLEEP STUDY EXPLANATION
Kaiser Permanente Sleep Center
 
FINDINGS (Diagnostic)
These findings help us to make a diagnosis of Sleep Apnea through the following information:
1. RECORDING INFORMATION
Total Sleep Time: Indicates how long you slept during the first phase of your sleep study. Normally
this time is usually less than 3 hours.
2. RESPIRATORY EVENT SUMMARY
Obstructive Apnea: Number of times that you quit breathing and the longest time in seconds that you
did quit breathing.
Mixed Apnea: A combination of obstructive and central apnea
Central Apnea: Apnea that is not obstructive, but an event that occurs from the respiratory drive is not
getting any information from the brain to breathe.
Hypopnea: Airflow is diminished and is not very effective. After alcohol some of these hypopneas
will turn into obstructive apneas.
AHI: Apnea Hypopnea Index or RDI: Respiratory Disturbances Index
AHI or RDI is an average number of events (apnea and hypopneas) that occur every hour of sleep.
American Sleep Disorders Association Classification of OSAHS
Mild: AHI 5-15 events/hour of sleep
Moderate: AHI 15-30 events/hour of sleep
Severe: AHI >30 events/hour of sleep
3. OXYGEN SATURATION
Amount of oxygen in your blood while you sleep.
4. AROUSAL
An arousal is a shift in the brain wave that disrupts your sleep. You may or may not awaken with
these arousals.
5. ELECTROCARDIOGRAM (if applicable)
Report of the EKG during your sleep.
6. MUSCLE ACTIVITY (if applicable)
This will show any abnormal leg movement that is shown during the study.
CPAP / BiPAP TITRATION (Treatment or Therapeutic)
Indicates the time spent during a CPAP or BiPAP titration, to determine the correct pressure. The
titration will reveal a reduced AHI or RDI that occurred during the CPAP/BiPAP titration. Most cases
the AHI or RDI will be :~5 events per hour with the CPAP or BiPAP recommended pressure. Also
your Sp02 or oxygen saturation will improve from therapy. Normally the time spent in a Titration is
between 4 and 6 hours.
CONCLUSIONS
The physician who reads your study will indicate the degree of your Obstructive Apnea and what the
best pressure that your CPAP or BiPAP will be set.

RE: Lindanhotair Treatment review
There is a lot to unpack here. You have apparently been able to upgrade your prescribed therapy from an auto CPAP to a Philips BiPAP Auto SV by purchasing out-of-pocket and modifying the ASV by removing the polyurethane foam. Your sleep study showed some indication of complex apnea, and you were apparently not satisfied with the CPAP therapy, and upgraded. I think the next step here is to post some Oscar charts of the therapy so we can see where you are at in terms of settings and efficacy. It would be useful to contrast both CPAP and ASV results, and comment on your sense of how the therapy is working out. I don't see a question, so let's see where your data takes us.

RE: Lindanhotair Treatment review
Here are some examples on the Auto CPAP.  I would run out of energy in the early evening and doze off in front of the TV.

RE: Lindanhotair Treatment review
Really interesting. I look forward to seeing the ASV results, but if this was all I had, I would tell you to read this wiki that characterizes these clusters of apnea as mainly the result of chin-tucking. http://www.apneaboard.com/wiki/index.php...onal_Apnea

RE: Lindanhotair Treatment review
Here are some screen shots of the ASV.  The AHI varies considerably. Here is a 2.99 AHI.
   
Here is last night.
   
Here is a 5 minute shot from last night.
   

The settings have not been changed significantly for some time, but there seems to be a lot of variance in the events.
Tidal volume and minute vent don't seem to vary as much as they did on the Auto CPAP.   My oxygen saturation stays high over night, typically 94 to 96. I don't often experience the tiredness in the evening that I did on the Auto.

Sometimes my patient triggered breath percentage goes to zero, and the machine forces ventilation.  That seems to happen quite a bit while I am starting to wake up.

My backup rate is set to 9 and that does not seem to be intrusive and I am not fighting with the machine.

Does anyone see anything that might need to be changed, or any improvements that could be made?  
I don't expect to chase the numbers to zero.  As for oxygenation, it seems to be doing its job.

I am currently using a ReLeaf soft neck support. I have a flat pillow that I use, but I change position during the night.

RE: Lindanhotair Treatment review
Well, in my experience the ASV treats complex apnea nearly 100%, and when we see the clusters of OA and H events, we have to fall back on the positional apnea and soft cervical collar as a remedy. From what I have seen in my considerable experience with seeing these charts, you need to look at a different collar. You have mostly obstructive sleep apnea, and it comes from position (chin-tucking). How many pillows are you using? Do you sleep laying down or more upright in a sitting or inclined position?

RE: Lindanhotair Treatment review
Here are charts from last night. 


Overview:
   
Flagged events:
   
Unflagged breathing:
   

There are a few times when the Patient Triggered Breaths dropped to or near zero, and my respiration rate dropped below the backup rate of 9.
The event count for timed breath is 355. Last night I did not remember waking up and moving around, and the AHI of 4.23 was lower than some nights.

RE: Lindanhotair Treatment review
I think the event you focused on at 03:52 looks positional. Your EPAP settings allow for a maximum of 22, but this chart does not exceed 14. I think the machine keeps EPAP above 15 in reserve for pressure support, so probably no need to keep settings above that level. For ASV, your pressure is relatively high compared to most. The best breathing of the night was at the minimum EPAP setting and PS.

RE: Lindanhotair Treatment review
The EPAP Min of 10 is the lowest pressure that doesn’t feel like I’m starved for air, and the 2.5 PS Min is comfortable unless my nose is congested. Then the machine increases it slightly. 

I will check out different neck supports to reduce positional apneas.

My mix of obstructive and central events can change significantly, with as many as 33 central events nightly, but on some nights obstructive events are higher. In most cases the hypopneas make up the bulk of the events.
Last night was 6 C, 7 O, 18 H. Last Saturday AHI 7.8, 20 C, 6 O, 41H.
