Peak flow good but SpO2 at 94?

[garss]

I'm having a really bad time with asthma lately, I've been to A&E a few times but they havne't done much about it. The thing is I don't have the classic wheezing symptoms, but I do feel short of breath, with pain and pressure in my chest. I use my peak meter and pulse oximeter to measure my oxygenation. At this point I have become quite anxious because I'm using prednisone and oral salbutamol to control it and my SpO2 reading is still at 94-95, occasionally dipping to 93. Anxiety gets mixed in an I don't know if I'm actually not breathing or if it's the anxiety. Is it safe to be at this level? The thing is, my peak meter reads 560, so I don't understand how they could be so different.

Hi there I'm 44 with a lung volume in the 40% range and just been told they think it's brittle asthma.What you've described is exactly how I feel my spo2 is at 94 most days and I am frequently at the hospital they never do much other than give me a nebuliser.I get chest pains in the middle of my chest and across my back and relate to your story so your not alone.All the best.
