During human growth and development from infancy to adulthood, dramatic changes occur in the respiratory system.
It is important to understand respiratory airflow in different age groups in age-specific treatment of respiratory disorders.
This study numerically investigated the age-related effects on inspiratory and expiratory airflow dynamics in four-generation lung airway models under normal breathing conditions.
Tracheobronchial airway models of infant (6 month old), child (5 years old), and adult (25 years old) from sixth to ninth generations were constructed for the study.
Computational fluid dynamics (CFD) was used to solve the equations governing the airflow.
Results of this study indicate that as age increases, airflow velocity, pressure, and wall shear stress decrease for both inspiration and expiration in this particular subregion of the respiratory tract.
During inspiration, the splitting of velocity streamlines at bifurcations increases with age.
The opposite situation merging happens during expiration, and it also increases with age.
The level of splitting and merging of streamlines here reflects the influence of respiratory mechanics in the age groups.
The computational models provide new information on characteristics and patterns of age-dependent respiratory airflow in the sixth to ninth generations of tracheobronchial airways and can be applied in other generations.
