This question asks, idiopathic pulmonary fibrosis or ipf is a disease in which scar tissue forms in the alveolar walls making the lung tissue significantly more stiff.
00:12
Which of the following findings would likely be detected through spirometry in a patient with ipf, decreased total lung capacity, decreased inspiratory reserve volume, or increased residual volume.
00:26
So if we're going to have stiffness of the lungs, this means that we'll see a decrease in the volume of air that an individual could inhale.
00:44
So what does this mean? well, this means that we'll see a decrease in total lung capacity as well as a decrease in inspiratory reserve volume.
01:06
And specifically inspiratory because that is when we are inhaling, we are inspiring that error.
01:13
So spirometry can't measure total lung capacity.
01:18
So here's the difference here.
01:21
Although, yes, total lung capacity is going to be a correct choice in that, yes, it will be affected.
01:27
Spirometry can't measure total lung capacity.
01:31
So we have to remember that when answering this question...
