Some athletes … If the TLC is larger than the upper limit of normal (generally around 120% of predicted), then the patient is hyperinflated. The only other number that is worth knowing about is the residual volume (RV). If the RV is too high (above the upper limit of normal), then the patient has air-trapping.
