Having had our diffusing capacity tested in a large number of pulmonary function laboratories, it is very alarming that we found that inter-laboratory DLCO
results varied by up to 60% through out our State of California, in hospitals as well as in private physician offices.
1] and DLCO
that were not more than 20% of predicted.
Bronchoalveolar lavage parameters were determined immediately after testing for DLCO
Bizim serimizdeki PAH hastalari dusuk DLCO
, dusuk 6 dk yurume mesafesi ve yuksek pro-BNP duzeylerinden (Tablo 3) anlasilacagi gibi gec saptanan olgulardir.
Dermatomyositis patients with a mildly low DLCO
(defined as 61%-75% of predicted) should also have a high-resolution chest CT, as well as echocardiography to rule out pulmonary hypertension.
test is much more sensitive and is able to pick up the earliest signs of emphysema.
Yapilan calismalarda, AS hastalarinda solunum fonksiyon testleri ve DLCO
anormallikleri saptanmistir (9, 11, 12, 24).
In multivariate regression models, 6MWT distance, self-report of being disabled, UCSD SOBQ total score, 6MWT Borg, age, and DLCO
percent predicted were significant determinants of PCS score (model [R.
In ILD, these two parameters tend to decline in parallel, whereas in isolated PAH, the DLCO
shows a disproportionate decline.
If no objective improvement (increased FVC or DLCO
by > 10%) occurs within 6 to 9 months of starting therapy, the drug should be stopped and potentially changed to a different agent.
In all cases, final reports should include name references to the predicted sets used for specific tests (spirometry, lung volumes, DLCO
ndd's devices measure DLCO
, FRC, LCI and FVC with their patented Ultrasonic TrueFlow(TM) technology, which requires no calibration and eliminates problems associated with traditional methods of flow measurement, making testing fast, reliable and error-free.
