Answer :
Final answer:
The patient's vital capacity is 2.7 liters which indicates a level of lung restriction, likely between moderate to severe given the significant reduction.
Explanation:
The patient's Vital Capacity (VC) is calculated by subtracting the Functional Residual Capacity (FRC) from the Total Lung Capacity (TLC). So in this case, VC = TLC - FRC which equals 6.2L - 3.5L = 2.7 L. The vital capacity of an adult male is usually between 4.5-6 L. Therefore, in this case, this patient's vital capacity is lower than normal, which suggests a level of lung restriction. It's hard to put a label on the severity without more information, but it's likely moderate to severe given the significant reduction.
