You doc was very clear: your upper lobes are working well; air's going in and out just like it's supposed to. You lower lobes aren't working as well, and you're trapping air; he can hear the air going in to your lower lobes, but can't hear as much going out. It's not at all unusual to have air trapping with COPD. Most of us have it. Some in the upper lobes, some in the lower lobes.

COPD

air trapping is something most of us with COPD have. It can come up overnight, I suppose, especially if you're sick or having an exacerbation. Or it might be that there's been more damage to the lower lobes in the interval between appointments.

That makes sense! I'm still awaiting my call for an appointment with the respirologist. It's been since June 17th since I last called to see if they had an appointment set yet. 6-8 weeks since. But it's almost that

Can it come up quickly? They didn't hear it 2 months ago
