Reducing the radius of the airways will affect the capacity of the lungs to exhale the maximum amount of air
In asthmatics, the airways become narrowed due to inflammation and constriction of the smooth muscles around the airways. This leads to difficulty in exhaling air from the lungs, resulting in a lower FEV1 (forced expiratory volume in 1 second) value. Additionally, increased mucus production in the airways can further contribute to decreased airflow and lower FEV1 measurements in asthmatics.
FEV 1 (%) will decrease as the airway radius is decreased. FEV 1 (%) is the amount of air that can be expelled from the lungs in one second during forced expiration. If the airway becomes smaller, then the resistance to airflow will increase and FEV 1 (%) will become lower.

FEV1 (forced expiratory volume in 1 second) measures the amount of air a person can forcefully exhale in 1 second, which is an indicator of lung function. Peak expiratory flow (PEF) measures the maximum speed at which a person can exhale air during a forced breath, providing information on how well the airways are functioning. Both tests are used in the diagnosis and monitoring of respiratory conditions such as asthma and COPD.
Bronchial spasm can lead to a decrease in air movement through the bronchial tubes, causing air to become trapped in the alveoli. This can result in difficulty breathing and decreased oxygen exchange in the lungs, leading to symptoms like wheezing and shortness of breath. Treatment may involve bronchodilators to help relax the airways and improve airflow.
British Airways officially stated reasons for ending Concorde flights were increased maintence expense and a decreased number of passengers (partly due to a Concorde crash in 2000, and to the decrease in air travel following the 9/11 attacks in 2001). While British Airways made a profit on Concorde flights, it has been suspected that they became convinced that it was even more profitable to fly the same passengers using conventional trans-Atlantic flights.
Acetylcholine causes bronchoconstriction by binding to muscarinic receptors on smooth muscle in the bronchioles, leading to narrowing of the airways. This can result in difficulty breathing and decreased airflow to the lungs.
