Central apneas of 0.9, is that okay?

I saw my central apneas on my Resmed s9 autoset, were 0.9 average. Is that something to be concerned about or is that okay do you think?

I just started on my cpap & have my first followup in 2 weeks time. I know my sleep Dr was concerned before I started cpap therapy as I was having some central events in my sleep study.
I do not know how many I was having prior to cpap therapy though. But thinking 0.9 sounds low, but then I average 7hrs of sleep a night, so if I multiply that by the number of hours, maybe it isn't too good?

How are you feeling? What is your total AHI? What pressure are you using? In general, sleep docs are not going to be unduly concerned unless you are feeling like &%@! or your total AHI is above 5. If the centrals occur when your pressure rises, they may be a little more concerned. If your total AHI is around 1, you are using the mask all night every night, and you are feeling good, your doc will congratulate you and tell you to keep doing what you are doing.

I feel tired in the mornings still. I normally wake around 4-6am & around 9-11.30am I get very tired. Feel like napping, yawning a lot. But I do not nap.
Dr set my machine at variable pressure (8-14, with a ramp)

Just checked my stats on my machine.
Pressure - 11.2
Leak 8L/min
AHI 2.1
Total AHI 1.7
Central 0.9


Just edited to add I use my cpap with mask every night too.

Your numbers look good. It sometimes takes a while for that feeling of needing a nap to fade away - remember that habits take a while to change! Some areas that you might want to discuss - what does the ramp start at, how long does it take to get you to your minimum pressure, and if you are using a humidifier at what level are you using that. With a minimum pressure of 8 you may find you don't need the ramp at all, but many people cannot stand the "usual" starting pressure of 4 cm. I couldn't. Felt like I was suffocating. Humidity is a very personal thing. Some people don't use it, some (like me) use it in pass-over mode (most of the time), and others use it at settings of 1 through 5. Increasing or decreasing the humidity can improve or worsen your AHI - the only way to find out is to experiment!

I think that's a pretty good number.

Remember that the machine will also flag awake/semi awake breathing irregularities as centrals..and they would be ignored in a sleep lab.
The machine doesn't know if you are awake or not...so it just calls them like it sees them and sometimes what it thinks it sees isn't anything to worry about.
Even if they were the real deal a central index of less than 1.0 means minimal centrals and certainly nothing to worry about.
Also it is entirely normal to have sleep onset or sleep stage transition centrals..so they are real but normal to see and only a problem if you have a truckload of them causing multiple awakenings or desats in oxygen levels. With an index less than 1.0...certainly doesn't qualify for a truckload.
I wouldn't worry about them at all. I see more than that quite often.. mine are most likely tossing and turning centrals when I have a restless night.

Sounds like perfect results here.

If your still tired then something is not quite rite. Monitor your O2 with a pulse Oximeter. Also check your vitamin D or just start taking vitamin D3 supplements. Take calcium(calcium carbonate pills aka tums) with a light snack about an hour before bed and magnesium(magnesium citrate) supplements about two hours before bed. Might as well do the B vitamins as well just do them early in the day. Just take it easy with them to see how you adjust to them. Low doses and gradually build up. If your struggle with cpap you might want to go to bipap as it is easier to breath with. If sinus issues are causing restriction you will likely see it in the O2 readings. Try to become aware of sinus problems. They can come and go real quick. A restricted nose makes Cpap/bipap miserable.

It does take awhile to learn and adapt to using the machine. It takes awhile to unlearn your bad sleeping habits. It could be months. Once you get used to the machine you won't be able to go without it and get restful sleep.
