Concern about Cheyne Stokes result on Oscar - makebikedesign - 11-25-2024
Hi there!
I'm a new Cpap machine user and Oscar user.
Last night I had some concerning results that I was hoping someone could walk me through.
I am open to any suggestions.
I attached an image of the results
Basically there were three sessions flagged as Cheyne Stokes
and a lot of CA events overall.
My machine is the Airsense 10 autoset
pressure is set to 6-20 and averages right about 10
My events per hour was 16
mask seal was good
leak 19L
Total IA 13.6
Central AI 10.9
Thank you.

Welcome to Apnea Board,
We're going to need a few bits of info to help out. You'll need your sleep study detailed report, and also what heart condition you have or don't have. OSCAR chart, you need to include the left panel data.
Your mask does leak moderately high from about 21:45. This negatively affects your comfort, probably increased disturbance, and hinders the CPAP ability to accurately track your events.
Your sleep study will tell you about the Central Apnea, and how bad they were or not. And CSR indicates a heart condition affecting your sleep breathing. This is, if CSR there flagged was real, because it's not always the case. Periodic breathing can be flagged as CSR events, incorrect labeling. This incorrect label isn't the fault of OSCAR but the CPAP program itself.
So get your sleep study details so you'll be able to attach them redacted of your personal info.

Hi there! your assistance is so helpful.
I took a lofta at home test and the results are attached.
As far as I know I don't have a heart condition though i have always been told my resting heart rate is low. Typically around 48 bpm. I'm not really overweight or an athlete .
Lastly I've attached the Oscar side panel.
Thank you so much for any help you can offer. I really appreciate it.

I'm realizing that the sleep report didn't come through.
Here is the text
Alvin Thomas Perkins, M.D.
Diagnosis
Severe (pAHI/RDI = 34/40) positional OSA (supine index 39, nonsupine index 14) with mild (naidr =
86%) intermittent
hypoxia []G47.33].
1) Auto-CPAP set 4-20 cm H2O with heated humidity and mask/interface fitting. Close follow up and
monitoring is
recommended to adjust pressures/masks if necessary
2) Alternate treatment options including oral appliance therapy (OAT), daytime neuromuscular stimu-
lation
(ExciteOSA), poitional therapy, and/or surgical procedures for OSA may be considered based on
severity and
comorbidities, if PAP is not tolerated or in combination with PAP
3) Avoid alcohol, sedatives and other CNS depressants that may worsen sleep apnea and disrupt normal
sleep
architecture.
4) Sleep hygiene should be reviewed to assess factors that may improve sleep quality.
5) If the patient has a BMI > 25, weight management and regular exercise should be initiated or
continued.
6) Avoid driving and handling machinery/equipment if sleepy

If I am reading your sleep study correctly, you have OSA only (and no CSA).
The CA's you are having are most likely treatment emergent - pretty common and most disappear in a few weeks to months as a person adapts to therapy and pressure(s).
The vast majority of the time, Resmed flags CSR incorrectly (it should be periodic breathing). A close up 3 minute zoom can confirm or deny this, but since have only OSA, then this is very likely falsely flagged. (Keep an eye on it for a couple of weeks and if it doesn't stop, repost an updated OSCAR chart with the CSR.
