FEV1 and FVC: What Do They Mean for You?
Diagnosis
Forced vital capacity (FVC): The amount of air you can blow out until you empty your lungs after taking a deep breath in, This is the largest amount of air that you can forcefully exhale after breathing in as deeply as you can, IC is the maximum volume

A Stepwise Approach to the Interpretation of Pulmonary

Results
FVC = forced vital capacity (a little lower than VC because of dynamic airway closure; normally ~5L) PEFR = peak flow rate over an expiration (normally 500L/min) FEV1/FVC (normal = 80%) – obstructive disease = FEV1 reduced more than FVC, more manoeuvres are required, Inspiratory capacity (IC) = TV + IRV, The reduction in FVC is also reflected by the low percent predicted value of 37%, Case 10A

FEV1/FVC Ratio
The FEV1/FVC ratio is almost universally used to determine the presence or absence of airway obstruction, This is the largest amount of air that you can forcefully exhale after breathing in as deeply as you can, Those who
Understanding ABGs and spirometry
Forced vital capacity (FVC): The amount of air you can blow out until you empty your lungs after taking a deep breath in, Inspiratory capacity (IC) = TV + IRV, There are several different threshold values for this, Functional residual capacity (FRC) = ERV + RV, Ratio of FEV 1 /FVC: This is the FEV 1 divided by the FVC, Results

Purpose of Test
Forced vital capacity (FVC), Ratio of FEV 1 /FVC: This is the FEV 1 divided by the FVC, whichever is greater,1.0 L, the best two values should be within 5% or 150 mL of each other, To confirm this spirometric restrictive pattern a referral for the measurement of Total Lung Capacity is required, If your doctor suspects that you have COPD, If FVC is, Forced expiratory volume (FEV).
Pulmonary Function Test
FVC is a measurement of the greatest amount of air you can forcefully breathe out after breathing in as deeply as you can, Forced expiratory volume (FEV).

Understanding ABGs and spirometry
[PDF]The FVC at 1.05 L is below the LLN of 2.00 L and has a Z-score of -3.75 indicating that spirometry is showing a restrictive pattern, This number is used to find out if you have COPD, however, A lower than normal FVC reading indicates restricted breathing, Functional residual capacity (FRC) = ERV + RV, A lower than normal FVC reading indicates restricted breathing, There is usually an upper limit of eight manoeuvres, To confirm this spirometric restrictive pattern a referral for the measurement of Total Lung Capacity is required, Procedure, Lower Limit of Normal (LLN): The ATS/ERS statement on interpretation recommends the use of the Lower Limit of Normal (LLN) for the FEV1/FVC ratio as well as the FVC and FEV1.
