Sorry to read that Chevy, God bless your sister and your whole family brother. You, along with the rest that shared in this post, have beautiful loving families. My family and I will pray for your sister's full and speedy recovery.
Chevy as to her desaturating on a O2mask ( I don't have her chart so this is just an orientation as to what the thought process may be)
The pneumonia (scary name for inflammation in the lung) is a common presentation of the lung by covid ( small sacks clustered like grapes =alveoli) which cause inflammation in the alveoli which makes the exchange of O2 for Co2 harder. Its like 3-4 people in a doorway that doesn't let anyone pass to and from easily. For this they'll probably use Broncho-dilators (albuterol is most common) to help push the gas exchange and open up the bronchial tree, and Prednisone ( a corticosteroid) to get rid of the inflammation ( the folks cluttering the doorway). As time passes and her viral load drops ( monoclonal antibody to kill virus) the inflation will decrease and she'll tolerate room air. That they challenged her by removing the mask is a good prognostic sign of improvement to me.
Her headaches could just be associated to the infection (mc) or possibly associated to cerebral hyper tension, due to the pneumonia (probably not) if its due to lungs it should improve as her respiratory status improves (again this is a possible reason but not the probable one. Being part of covid symptoms is probably why)
The loss of Energy is turning into a Hallmark of this bug. The Spike Proteins the virus uses is a bad mofo and every time it touches a cell it blows up the mitochondria ( basically the mitochondria is the Power House/ Energy Generator of the cell) so you lose energy. The feeling of low energy has high and lows and this is because some days the spike doesn't interact much so you don't feel as drained, and other times its a wrecking ball and you feel like your caving in or imploding. This will improve as that monoclonal AB kicks covid butt and lowers the Viral Load. God Bless you brother and your love for your family hopefully everything will go smoothly.🙏
801 you blew my mind I'm so sorry about that quack. Worse thing any Dr could ever do is cause more suffering, should of never went to work if he/she knew . There are many awesome people on these boards and this thread is proof +.
Proud to be !
