In a conversation about a much more pressing issue, the doc mentioned that my fiancees asthma is not so much deep in her lungs, but more at the top. We're going to follow up with the doc about this later this week, but I was wondering if anyone out there knows what the significance of this would be as far as diagnosis, prognosis, treatment, etc. Thanks.
There is no such thing as the 'lower trachea' as your trachea stops and splits somewhere around the second rib, or 2-3 inches above the nipple line. From there on it is not called the 'trachea', it's called the bronchus (bronchi, pl.)
As for asthma being at the 'top', the sensation of bronchospasm being so "high" in the chest can sometimes be attributed to vocal chord dysfunction (except that's more a throat-feeling than a chest-feeling) and also to a misunderstanding about how high up in your body your large airways actually are.
Besides, lungs are a lot like trees in that there's a branching and branching and branching action until the airways are microscopic nearly and the alveoli are microscopic surely. So at the uppermost point in your lungs you have 'deep' alveoli, just like you do at the lowermost point in your lungs.
Other than that I can't understand what she might possibly be getting at.
