Increase in apnea events

I have been on a bi-pap for over two years and have had great results. I have worn it every single night since getting it. My events have consistently been below 5 during that time. Oh I had the occasional increase due to a leak here and there or needing to replace a worn out mask but have had great success with the treatment, until recently. Over the last several weeks my apnea events have been increasing and can range from 7 to 17. Yes, I have a new mask, tubing, headgear, etc and there is no significant leakage. The only thing that has changed over the last 2 years has been weight loss over the last 30 days. This has been intentional by changing my diet to eating healthier and exercise. I am not obese but was overweight. I am 5'10" and weighed 222 pounds. Over the last month I have lost 20 pounds on my way to my ideal weight of 180 pounds. I am 53 years old.

My question is this: With my weight loss, is my apnea improving to the point where the bi-pap is actually causing my events to increase?

Welcome to the forum. I think your suspicion is a possibility. A higher pressure can in some individuals initiate more central apnea events. However, I'm not sure that would be weight related. Do you know what your breakdown of central to obstructive events has been in the past, compared to now?

It would be very informative to see a Daily Report from SleepyHead from a couple of your typical problem nights. It will tell you when the events are happening in relation to the pressure the machine is using. SleepyHead is free, but you need a PC or a Mac and a SD card reader to use it. If you want to give it a try here are a couple of links. On a PC you can save a screenshot by just pressing F12. It makes an image file in your SleepyHeadData/Screenshots directory. Then to display it in a post here, just left click and drag the file from Windows Explorer to the body of your message.

You could be correct if you are being hyperventilated. Perhaps a retitation study is in order.
