This is Kitt and I am sorry your having respiratory problems.........I am sure this is affecting your anxiety level.
FVC - Forced Vital Capacity - after you have has taken in the deepest possible breath, this is the volume of air which can be forcibly and maximally exhaled out of the lungs until no more can be expired. FVC is usually expressed in units called liters. This PFT value is critically important in the diagnosis of obstructive and restrictive diseases.
