Trouble shooting resmed 100
Hi. Just went to use my resmed lumis 100 tonight. With my oxygen concentrator on. Oxygen fine as I used it at tea time abd can feel the oxygen coming through when i take the cable out. It felt like no oxygen coming up through the mask and almost felt like I couldn't breathe properly. And my face was warming up. Felt clostraphobic. Felt like there was no force on my breathing. It started up okay. Something didn't feel right. Any ideas? Hope this make sense.
