Nitrogen washout (or Fowler's method) is a test for measuring anatomic dead space in the lung during a respiratory cycle, as well as some parameters related...

Other complementary lung functions tests include plethysmography and nitrogen washout. Spirometry is indicated for the following reasons: to diagnose or...

to measure RV precisely, one would need to perform a test such as nitrogen washout, helium dilution or body plethysmography. Positioning plays a significant...
