Your FEV1 score on its own isn’t used to diagnose COPD. A COPD diagnosis requires a calculation involving both FEV1 and another breathing measurement called FVC, or forced vital capacity.

An FEV1 between 50-80 percent indicates moderate COPD. An FEV1 between 30-50 percent indicates severe COPD. An FEV1 of <30 percent indicates very severe COPD. The Relationship between FVC and FEV1. As you might guess, FVC and FEV1 are closely related. Your FEV1 is divided into your FVC, and the resulting percentage determines whether you have COPD.

Kvar i lungorna finns residualvolymen (RV), VC = Vitalkapacitet (lungvolym i liter vid långsam utandning, säkrare vid KOL-diagnostik).

Forced expiratory volume (FEV1) is the maximum amount of air you can forcefully exhale in one second. It is used to describe the degree of airway obstruction caused by asthma in a routine test called spirometry or pulmonary function testing, using an instrument called a spirometer. 1

Your FEV1 is divided into your FVC, and the resulting percentage determines whether you have COPD. Relationships between exercise parameters and lung function were examined by regression against FEV1 expressed as percent predicted. There was a significant positive correlation between VO2max percent predicted and FEV1 percent predicted (p < 0.02), and a negative correlation between FEV1 and end-expiratory lung volume (EELV) at maximal FEV1/FVC ratio as low as 50 % The FEV1/FEV6 ratio below LLN has a positive and negative predictive value of 97 % for diagnosis of airway obstruction When using fixed cut-offs, one may refers to the conclusion by two large population studies that FEV1/FEV6 < 0.73 is an valid alternative to the FEV1/FVC < 0.70 to diagnose airflow obstruction FEV1 may be a better indicator than vital capacity – if FEV1 is > 2L, mortality is ~ 10%, whereas for FEV1 < 1L, mortality may increase to > 20% [Lockwood P. Respiration 30: 529, 1973]. Maximum voluntary ventilation < 50%, and RV/TLC > 50% [Mittman C. Am Rev Respir Dis 84: 197, 1961] may also be predictive If the FVC and the FEV1 are within 80% of the reference value, the results are considered normal. The normal value for the FEV1/FVC ratio is 70% (and 65% in persons older than age 65).
