Forced expiratory volume 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.

FEV1 = Det forcerede udåndingsvolumen i første sekund er det volumen, som udåndes i det første sekund efter en maksimal indånding. FEV1% = Er forholdet mellem FVC og FEV1 dvs. FEV1/FVC. FEF 25-75% = Forced expiratory flow: Dette er flowet eller hastigheden på den mængde luft der kommer ud i den miderste del af Den forcerede udånding (FEV).

Kvoten FEV1/FVC. Kallas även FEV% eller FEV1%. uppvisar positivt reversibilitetstest (FEV1-ökning med ≥ 10–15 procent) i diagnostiskt syfte • hög specificitet på 90–100 procent, men låg sensitivitet på 6–35 FEV1 z. -0.07. (0.97). FEV1 z.

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. In test terms, obstruction is defined as a reduced FEV1/FVC ratio (meaning forced expiratory volume in 1 second per forced vital capacity) to less than 0.7 combined with a FEV1 of less than 80%, in severe cases, FEV1 reaching less than 35% of the predicted normal. The most common symptoms are dyspnea or breathlessness, cough and sputum production.

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.

However, no one can maintain such a respiratory minute volume for long periods, and clinical experience reveals that for people with serious COPD, the sustainable respiratory minute volume is about 50-60% of the MBC ( Zocche-1960 ). 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.

FVC, forced vital capacity, is the full amount of air that can be exhaled with effort in a complete breath. Less than 35%: very severely abnormal: FEV1/FVC ratio. The FEV1/FVC ratio is a number that represents the percentage of your lung capacity you’re able to exhale in one second. The higher the 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.
