Pulmonary Critical Care 14 years experience. 2004-05-04 Next, look at the FEV1 parameter to see if it's within the normal range. If both the FVC and FEV1 values are normal, in all likelihood the results of your spirometry test can be considered normal. If either the FVC and FEV1 values are below the predicted normal value, there is a possibility of lung disease and you should go on to step 5.

Normal range FEV1 is between 3.0 and 5.0 L whilst normal range FEV1 is between 2.4 and 4.0 L. Lower FEV1 values are indicative of obstructive lung disease, such as asthma or COPD.

Therefore, a patient with an FEV1 of 1.2 liters would be very high risk for a pneumonectomy (predicted post-op FEV1 = 0.6 L) but only moderate risk for a lobectomy (predicted post-op FEV1 = 1.0 L). The pCO2 is also valuable; carbon dioxide retention > 45 indicates increased risk of pulmonary complications of surgery.
