When the values of Fev1=1.3 & FCV=3.9.
Which of the following does this
signify? #PYQ#FMGE#NEETPG#INICET

Correct Answer - B
Ans: B. Obstructive lung disease

Measurement of the bronchodilator response of forced expiratory
volume in 1 second (FEV1) is an important method in clinical
respiratory medicine.

This measurement is used to predict the response to bronchodilator treatment and is part of the diagnosis of COPD and asthma.

The bronchodilator response of forced vital capacity (FVC) has less
clinical use than the bronchodilator response of FEV1 but may add
important clinical physiological information

Airway obstruction was defined as FEV1/FVC ratio below lower limit
of normal (LLN) before bronchodilation, and COPD was defined as an FEV1/FVC ratio below LLN after bronchodilation.
