Abstract

Developed is a mathematical model that describes airway heat, water, and soluble gas exchange which has been used to explain the impact that breathing technique and inspired air conditions have on breath alcohol [blood:gas partition coefficient (λ)=1760] concentration. The model predicts that alcohol exchanges entirely with the conducting airways and not within the alveoli. On inspiration, the air reaches equilibrium with the partial pressure of alcohol in the bronchial circulation prior to entering the respiratory bronchioles. On expiration, approximately 20 - 50% of the alcohol absorbed from the airways during inspiration is redeposited to the airways, depending on the breathing maneuver.
