Ava will get a bronchoalveolar lavage (BAL) done tomorrow (Wednesday) to determine if Ava has a viral or fungal pneumonia. The procedure involves inserting a scope through the mouth/nose to the lungs, and injecting fluid to collect cells. The fluid is then collected for examination. The BAL is the procedure that only catches the presence of fungus 20% of the time and can also give false negatives.
Ava's oxygen saturation continues to be in the low 80's when breathing on her own, so she is getting a decent amount of supplemental oxygen (2.5 L). The doctors are also looking into the possibility that Ava may have some lung damage as a result of radiation.
As you can imagine, it's quite a juggle with 3 kids to care for, one being a newborn. Thanks for your continued prayers for Ava, as well as for stamina, rest and peace for the entire Lee family.
