Why Would An Asthmatic Attack An Impact On The FEV And MVV?

During an asthmatic attack, airway inflammation and bronchoconstriction occur, which can significantly reduce airflow. This leads to a decrease in Forced Expiratory Volume (FEV), as the individual struggles to exhale forcefully due to narrowed airways. Additionally, the Maximum Voluntary Ventilation (MVV) may also be affected, as the ability to take in and expel air rapidly is compromised. Consequently, both FEV and MVV are diminished, reflecting the severity of the obstruction in airflow.
