Channel Man Stan's vital signs are improving. He is stable and his overall condition and blood oxygenation levels have improved enough that the doctors have lowered the FiO2 level on his respirator to 50% to test what he can tolerate. Kidney function is of primary concern at this point. A renal specialist is being consulted this morning to determine a strategy to improve things. The Physician's Assistant monitoring Stan said, "Things are still critical, but we no longer feel like they are minute-to-minute."
