I went to the doctor because I am not sleeping well again after using a CPAP machine for more that a year. My settings for the pressures are set at 24 & 23. I am averaging in a month over 70 AHI and 34 Central AHI. I became very alarmed, and my doctor said he is getting authorized a new VPAP machine. He said this will help. But I still question what risk am I taking with such high numbers of daily. Events? My doctor does not seem to be very concerned with my situation.
Also, my personal condition is complicated because I have a implanted medical device (Pain Pump) which drips morphine directly into my spine. The doctor feels this is mostly the cause of the large number of nightly events. I. Question this because I have had this pain pump for over 10 years and the volume of medication is very low. I am able to drive a automobile and do most anything.
My question is how do I bring down the daily number of events and at what level of risk am I taking by having such high numbers of AHI's ?
I am confused about the numbers you quoted. Are you saying that for a whole month you have 70 events with 34 of them being centrals or are you saying that for a whole month you averaged 70 events per hour with 34 of them being centrals?

"I am averaging in a month over 70 AHI and 34 Central AHI"
Is a confusing statement. AHI stands for Apnea-hypoapnea per hour Index.
It's an average over the night. You cannot add them for the month.
(You can add total events for a month and divide by the total hours slept for a month.)
So, I'm going to assume that you're seeing about 70 AHI for a night +/-
That is in the severe classification for Sleep Apnea.
You are running high pressures -- so, you cannot gain much from a pressure change.
In my amateur opinion, I'm going to side with the doctor and say the morphine is likely an issue.
Sedative drugs like Opiates and Benzodiazapines reduce the brain's central ventilator drive; and relax muscles like those that hold the airway open.
VPAP is ResMed's name for a bilevel machine. Bilevel machines can run a wider gap between IPAP and EPAP pressures; and may help people whose breathing is shallow. Bilevel is also used for patients who have difficulty with compliance on CPAP.
