Abstract :
Constant temperature hot wire anemometers are widely used in measuring fluid velocity. In this work it is shown that such system can be used to measure fluid flow in the forced oscillations technique applied to the human respiratory system, in substitution to the pneumotachograph. Experimental results are shown to compare the proposed system with the original one.
