Roscoe's CO2 numbers were slightly lower (good) today. The previous measurement was 78 and today's measurement was 75. Hopefully these numbers will drop over time as Roscoe's lungs grow and heal. He is still on vapotherm with 4 liters of pressurized air at 32% oxygen. Though this feels like a step backwards (given the levels he was at a few weeks ago), I am thankful that he didn't get put back on the bubble CPAP, which the doctor mentioned might happen if his numbers continued to get worse.
