ResMed AirSense 10: Are Software Updates available?

Sat, 17 Jun 2023 13:18:11 -0700

ResMed CS reports that due to cellular updates, the CDMA can no longer connect to the cloud.

Is there a way to update either the device SW or the internal modem SW to restore connectivity?

Or a way to give it access to my WiFi so that it can "Phone Home"? ResMed says that I should ask my provider. But why should a respiratory therapist or doctor know that? ResMed should provide this support (or update) to their device.

Respironics EverFlo: no air produced even though green light is on

Tue, 27 Jun 2023 16:58:47 -0700

The concentrator turns on, all three lights come on at first for a few seconds, then only green. However, there is no O2 being produced, the gauge stays at the bottom, no tubing or cannula attached.

Before this the red alarm light and sound came on after a few seconds and stayed on, so I replaced the filter. Now the concentrator has the above condition with the new filter and also with the old filter put back.

After running the concentrator for several minutes with the new filter (which does not seem to be the problem) the red light comes on and the alarm sounds continuously until I turn the machine off.

Ventilator: PLV-100 Repair Technician Consultation Needed

Thu, 01 May 2025 16:37:43 -0700

My wife's used a PLV-100 since we were teenagers (that makes over 30 years now). We now have a few of them, and a bunch of spare parts, but nobody to service them and, unfortunately, we've not found any others she can breath on due to the uniqueness of the non-invasive ventilation setup she uses. (I don't want to go into that at the moment). Now, my goal is not to have to rely on anyone so I'm trying to find a professional to consult with to learn the ins-and-outs of the thing. I have the manual, and have taken the things apart, but no experience with actually servicing or repairing them.

Now, I've spent my years as a caregiver for her making things for her. She's 'everything' to me. I do electrical engineering and mechanical design, I even design and 3d print custom non-invasive ventilator nosepieces/headgear for her, designed our own feeding pump system with controls, etc. (Everything's approved by high up doctors and even local hospitals). BUT... a pro's a pro!

I'm willing to pay for the help and experience. Thanks.

(I'm not sure if we can be contacted through here, so please feel free to email me at jaggz.h {over yonder at} gmail.com

Thanks again; we're getting desperate as these things haven't been serviced in a long time, since Philips-Respironics terminated support of the line.
