Yes!: Blood oxygen level of 92% is likely at rest and when you walk it should go further down, limiting your activities. The poor appetite relates to infection and also to low oxygen level. Insurance does not pay for oxygen supply until you have 88% or less, although you will be short of breath with effort due to lung issues. Continue close care with your doctor to see resolution of this problem.
