Pathophysiology & Clinical Findings of the Disease
1. Are the spirometry results consistent with obstructive or restrictive
pulmonary disease?
What is the most likely pulmonary diagnosis for this patient?
The spirometry results are consistent with obstructive lung disease
since the patient has forced expiratory volume in one second
(FEV1) is reduced, as seen in obstructive pulmonary disease, and
the normal range is >80% (Global Initiative for Chronic
Obstructive Lung Disease, 2021). In addition, the patient's
FEV1/FVC ratio is less than 70%, with a 69% pre-bronchodilator
prediction and a 64% post-bronchodilator forecast. The TLC is
125, and the TLC range for the obstructive pulmonary disease is
>120%, which is deemed normal. Chronic Obstructive Pulmonary
Disease (COPD) is the most likely pulmonary diagnosis for this

patient. The patient has been experiencing difficulties for nearly
three months and attempts to alleviate some of his problems have
been unsuccessful. In addition, the patient had a 35-pack-year
smoking history. Dyspnea with exertion is a classic symptom of
COPD, and his chest x-ray shows hyperinflated lungs with a
flattened diaphragm.
2. Explain the pathophysiology associated with the chosen pulmonary
disease.
Shortness of breath is a sign of chronic obstructive pulmonary
disease (COPD) when patients have trouble expelling all of the air
from their lungs. COPD is an inflammatory condition that involves
airway thickness, increased mucus production, and probable lung
structural alterations (McCance et al., 2019). COPD affects the
lungs by causing fibrosis of the tiny airways and a loss of elasticity
due to the deconstruction of the lung parenchyma, including the air
sacs. When the lungs' structure is deconstructed, it leads to airflow
resistance, air trapping, hyperinflation, dyspnea, coughing, and
additional mucus
