Has anyone experienced oxygen level going down to 73 or resently 71? I was told at the hospital that 10 more min n I would have fallen back to sleep n died. Mon my o2 was 71 n I pushed my Oxygen concentrator up to almost 4cwhich brought me up to 80 ..drank lot of water n stayed at 92 Mon n tues n better today. If I go to the hospital I can't get an I.V. my arm swells n burns within 10 min. And I.v. has to be removed n they keep trying. I tell them over n over I can only have a pick line. It takes a while cause some doctors have to show that they can do it's it cant be done. Tired of fighting Drs egos. Sorry . so I stayed home . people were texting to press my lifeline. But when u are alone it's hard to go to hospital. I monitored my oxygen constantly. Thank you n love to hear back . i am sure I'm not alone ty .well they wouldnt let me show the photo of my arms . but anyone else have a problem with getting I.v.?
