CPAP data, decoded
Finally understand your CPAP data — in plain English
Upload your SD card. SleepSignalsIQ turns thousands of numbers into a clear picture of your sleep: what's working, what's not, and what's changed. Stop guessing why you're still tired.
- Works with ResMed AirSense 10 & 11
- Nothing to install: last night's data, right in your browser
- Free forever plan · no credit card required
You've got the machine. But is it actually helping?
Your doctor sent you home with a CPAP. The machine shows you a number or two on its screen, but nobody explained what "good" looks like, or whether you're anywhere near it.
Meanwhile, the SD card in your machine is quietly recording every breath, every leak, every event, night after night.
That data holds the answers. It's just locked in a format built for engineers, not for people trying to get a good night's sleep.
What you get
Your sleep data, finally in plain English
SleepSignalsIQ reads all of it: the same therapy data a sleep clinic reviews.
You get three answers.
How you slept
Your key numbers, in context, so you know if they’re good or need attention.
What’s getting in the way
Mask leaks, remaining events, or usage gaps, spotted for you.
Whether it’s working
How this week compares to last, so you can tell if a change actually helped.
Sample report
See it before you sign up
The same metrics you get after your first upload, including an estimated RDI that counts disturbances your AHI leaves out.
Below: mask leak, machine settings, every event. SpO2 and Apple Health on Pro.
One of our own accounts, not a customer's.
Beyond AHI
There's a third kind of event, and AHI doesn't count it.
RDI, the Respiratory Disturbance Index, counts every breathing disruption:
Arousals count on their own: for every 10 more per hour of sleep, the odds of hypertension rose about 10% — even after accounting for AHI. PMID 34970921 ↗
- Normal < 5
- Mild 5–14
- Moderate 15–29
- Severe 30+
Built to a sleep technologist's specification, not a generic threshold. A registered sleep technologist scores real nights against the detector to check we got it right.
An estimate from your CPAP's airflow data, not a diagnosis.
What the research says
Why the numbers on your machine matter
Heart and circulation
-
Severe OSA is associated with more than 2× the risk of death from any cause, and nearly 3× the risk of cardiovascular death.
PMID 27502205 ↗ -
Severe OSA is associated with roughly 2.15× the risk of fatal or non-fatal stroke, and every additional 10 events per hour of AHI with about a 17% increase in cardiovascular disease risk.
PMID 24161531 ↗
Sleep quality and oxygen
-
Higher nighttime arousal burden has been associated with increased long-term cardiovascular and all-cause mortality.
PMID 33876221 ↗ -
Among 10,701 adults, mean nighttime oxygen saturation below 93% was associated with substantially higher risk.
PMID 23770166 ↗
Metabolic health
-
Across 16 cohort studies, OSA was associated with a 40% higher risk of developing type 2 diabetes, and each additional 5 events per hour of AHI with roughly 8% more risk again.
PMID 31872550 ↗
Brain and memory
-
In a meta-analysis of more than 5.2 million people, sleep apnea was associated with a 28% higher risk of Alzheimer’s disease, a 34% higher risk of dementia, and a 64% higher risk of Parkinson’s disease.
PMID 39963034 ↗
Cancer risk
-
OSA was associated with a 36% higher overall cancer risk, rising to roughly 2.62× in moderate-to-severe disease.
PMID 36129602 ↗
These describe risks associated with untreated or under-treated sleep apnea in published research. They are not predictions about any individual, and nothing here is medical advice.
Why it's different
You shouldn't need a course to read your own sleep.
Other tools (and your machine's screen)
- Assume you already know what’s normal
- Leave you to interpret — or panic — on your own
- Expect hours of learning before they help
SleepSignalsIQ
- Tells you if it’s good, borderline, or worth a call to your doctor
- Puts one bad night next to the thirty around it
- Built for you, the person trying to sleep
