nitrogen washout test single breath
- nitrogen washout test single breath
- the patient inhales a vital capacity's volume of pure oxygen and then slowly exhales. The nitrogen concentration of the exhaled gas is measured over the entire breath and a curve is generated; different parts of the curve represent nitrogen concentrations of gas in different components of the vital capacity, and can be analyzed for uniformity of ventilation and determination of anatomic dead space and closing volume. Called also single breath t. and single breath oxygen t.
