Document Summary
Back to last lecture cast study 1: obstructive: She will have an alered ratio of fvc 1/fev. Vital capacity is max in to a max breath out. Tlc can be the same or it can be elevated because we tend to accumulate ar in the lungs. Fev/fvc can be normal or it can be slightly increased. In this disease theres a problem with getting air into the lungs. There can be an increase or decrease in rv. In the case of pulmonary fibrosis, rv is lower. Vc decreases because you cant fully expand the lungs. Other diseases are interstitial lung disease, tb, obesity, neuromuscular disease. Review: if (cid:449)e do fev(cid:1005)/fvc its o(cid:374)l(cid:455) 5(cid:1004)%, so its telli(cid:374)g us it"s a destru(cid:272)ti(cid:448)e lu(cid:374)g disease. Also (cid:271)e(cid:272)ause lu(cid:374)g volume is high and rv is also high. It would be easier to hold ur breath the 2nd time because we hyperventilate.
