58
Q

DX of ILD?

A

PFT in ILD?

FEV, FVC, FEV/FVC, TLC, RV, DLCO

A

FEV, FVC, TLC, RV, DLCO = decrease

FEV/FVC = increased

60

SAAG calculations & meaning…

A

(SAAG = serum albumin - ascites albumin);

SAAG = albumin concentration of serum - albumin concentration of ascitic fluid.

SAAG > 1.1;
Ascites is due to an imbalance between hydrostatic and oncotic pressures;(portal HTN)
• Chronic liver disease.
• Massive hepatic metastases.
• CHF.
• Portal-vein Thrombosis.
SAAG < 1.1;
Ascites is due to protein leakage;
• Nephrotic syndrome.
• Tuberculosis.
• Malignancy, (e.g., ovarian cancer).
• Pancreatic ascites.
• Biliary ascites.
• Serositis.
• Bowel obstruction or infarction.
• Peritoneal Carcinomatosis.
