QuestionSBA
QuestionChoice
If the FEV1 is reduced and the FVC is increased, the FEV1:FVC ratio would be expected to be < 0.7, as opposed to > 0.7.

c
Reduced FEV1, increased FVC, FEV1:FVC ratio > 0.7
QuestionChoice
The FEV1 is reduced in COPD due to inflammation of the airways, rather than being increased.
10002336
e
Increased FEV1, increased FVC, FEV1:FVC ratio < 0.7
QuestionChoice
The FEV1 is reduced in COPD due to inflammation of the airways, resulting in a decreased FEV1:FVC ratio.

d
Increased FEV1, reduced FVC, FEV1:FVC ratio > 0.7
QuestionChoice
This patient is presenting with signs and symptoms of chronic obstructive pulmonary disorder (COPD), as characterised by his extensive smoking history. As COPD is an obstructive respiratory condition, it results in a reduced forced expiratory volume (FEV1) as the airway inflammation allows less air to be exhaled in one second. However, the forced vital capacity (FVC) remains normal, which leads to a reduced FEV1:FVC ratio.

a
Reduced FEV1, normal FVC, FEV1:FVC ratio < 0.7
QuestionChoice
These spirometry results are more likely to be seen in restrictive respiratory conditions, as opposed to COPD.

b
Reduced FEV1, reduced FVC, FEV1:FVC ratio > 0.7

A 68-year-old male presents to the respiratory clinic with symptoms of breathlessness and a persistent cough. He mentions that his breathlessness is usually apparent on exertion, but he does feel quite breathless at night as well. The patient has a past medical history of type 2 diabetes and hypercholesterolaemia, for which he takes metformin and atorvastatin respectively. He has a smoking history of 25 cigarettes per day for approximately 40 years.

Given the most likely diagnosis, what would be the most likely spirometry findings in this patient?
