Answer Posted / rajnikant

As per USP guideline the normal healthy person is having
Lungs Air volume Capacity is 4lit. and when we measure the
air flow at that litre,so flow metre will show the air flow
60.
thus it mean 1 second per 1 Litre, so for the 4 litre is
required 4 second , that's why we performed the Andeson
Cascade at 60LPM/MIN and at 4 second
