Introduction
This paper aims at evaluating concepts of alteration in homeostatic state, secondary to temporal variables. It analyses the case study of Brad, a 45-year old coal cutter who has held the job for 25 years. Brad is experiencing a chronic cough due to prolonged exposure to coal. Importantly, he has not been attending yearly checkups because he fears that his lung is “black.” The disease leads to fibrosis, reduced diffusing ability, and dilation of the small airways. In the final stage, the airways, alveoli, and pulmonary capillaries become damaged.
How the disease described in the case study creates incongruous between ventilation and perfusion
Chronic lung disease may induce mismatch in ventilation and perfusion ...
