Above: a nighttime, deep sleep oxygen reading of 98%
C has not had any supplemental oxygen in over a month, and he's doing great! The school nurse checks his O2 levels every day, and we check them at night when he's in a deep slumber, the time when oxygen levels often drop. His levels are always 97% or above. As a point of reference, anything above 94% is considered healthy.
According to his last pulmonary function test, his lungs still have room to improve. In terms of oxygen delivery, however, they're getting the job done! If we can make it through flu season with no setbacks, it should be smooth sailing henceforth.
