Dad had a another good night. Tammy, his nurse for this shift, reported that his vital signs were about the same as last night. However, his blood oxygen saturations (SpO2) had increased to 100%, so they had lowered the amount of oxygen he was getting (FiO2) to 60% and then again to 55%, which was where things were yesterday evening. The doctors will be completing rounds later this morning and formulating a care strategy for the day, and everyone is eagerly anticipating results from the lab.
