May 2024: 98% (34% improvement since 10/22) Nov. 2023: 95% May 2023: 91% Oct. 2022: 73% TLC (total lung capacity) is the total volume of air in the lungs after inhaling as much as possible. May 2024: 102% !! (48% improvement since 6/22) Nov. 2023: 95% May 2023: 83% Oct. 2022: 72% Jun. 2022: 69% DLCO (diffusing capacity of lung for carbon monoxide, aka diffusion) is the extent to which oxygen passes from the lungs into the blood. It indicates the extent of lung damage....
