Can a patient have both? If so, what are the unique markers for a patient with both airways and alveolar dysfunction? Is there a name for this type of condition?
Your video helped, thank you! But, I don't understand the pursing lips example. Why do you purse your lips on exhalation, and not on inspiration. It is not like your bronchioles dilate during inspiration, and constrict during exhalation. Would it not be breathing in through pursed lips, and breathing out through pursed lips? I understand this may just be an example of what happens in our body, but anatomically it does not translate because, I believe, you'd just need pursed lips the entire time. I could be wrong! Let me know! Either way I'll remember your rules of thumb.
Because inhalation on ventilators, controled by ventilators, and you can ajust desired preasure and volume tu inhale. Exhalation is passive procese and not depend on ventilator. in other words if there is obstruction, exhalation becomes big job for patient, not inhalation wich is controld by ventilator
it made me wonder too bc people ith copd do pursed lip expiration to prolong expiration and thus getting more air out .. in the video it says this traps the air which i don't think so
