I Have Bronchitis. An Oxygen Level Of 94 With A

I have bronchitis. An oxygen level of 94 with a pulse of 120. I have a sudden onset o tiredness but feel as though I could faint. With a breathing treatment it goes to 96 but does not stay there. I tend to stare into space am aware of surroundings but nothing phases me. I guess I will take my chances I can't afford this right now with the medication and breathing machine. Maybe my 10-year-old can watch me. Thaks anyway.
