Hello @briancody, Welcome to Connect. I am sorry to hear you were recently diagnosed with lung cancer and you have never smoked. There is an older discussion where members who have never smoked were diagnosed with lung cancer. I believe the members are still active on Connect so you may be able to ask questions and share information in the discussion here - Never Smokers & Lung Cancer: https://connect.mayoclinic.org/discussion/lung-cancer-never-smokers/

If I am reading your post correctly, you've only been using the ResMed Airsense 10 CPAP since you were diagnosed in December 2020. The good news is that ResMed CPAP devices are not part of the recall. The recall was only for specific Philips Respironics devices. I had two of them with the recall and have switched to using a ResMed AirMini CPAP. You can find out more about the recall here - https://www.usa.philips.com/healthcare/e/sleep/communications/src-update

You may also want to look through the different discussions in the Lung Cancer group if you have any questions - https://connect.mayoclinic.org/group/lung-cancer/

That's good news that the chemo and immunotherapy is going well and your cancer has been reduced. Do you have any other questions you are trying to get answered?
