Fowler’s method is employed for the measurement of:-
Correct Answer: Anatomic dead space
Description: Methods used for various studies: - 1. Bohr's method: - Physiological dead space 2. Fowler's method: - Anatomic dead space. Based on single breath nitrogen analysis technique. A person is given 100% oxygen in single breaths, that breath enters alveoli Now the person stas exhaling out, the first air that comes out, it had never reached the alveoli, it is coming out of dead space only from the anatomic dead space. The first pa of exhaled air is last pa of inhaled air. So, when the person sta exhaling, he exhales the last pa of inhaled air first, which is air in anatomic dead space. This first exhaled air is analyzed, & this air will contain only O2. This is fowler's method. Used to measure functional residual capacity 3. Residual volume: Helium dilution method Nitrogen washout method.
