I bought an oximeter from Amazon and it consistently reads low sat levels of 84% to 90 %. When it read 84% yesterday after a gruelling outing of brethlessness I made some phone calls. One to my GP who called me in and used his oximeter..it read 95%. Thus he wasn't alarmed but is having an ECG and blood test done on me as my heart rate is always 100+.
Are these publicly sold oximeter machines generally OK?
I'd also left a message at the hospital and a pulmonary nurse rang today to ask me to come in Friday for a walking test as to whether I need to be on oxygen. I think they will say I do.
This exacerbation is gong full speed it seems to me and I feel somewhat panicky. I'm going to spend two quiet days at home and see what Friday brings.
