Measurements of airway mechanics in spontaneously breathing young children
Abstract
This paper gives an overview of the general principles of airway mechanics and methods to measure lung fuction in non-sedated, spontaneously breathing young children. Although lower airway obstruction is probably best evaluated using FEV1, other techniques can be applied when such measurement is impossible, as in young children. These techniques include measurement of resistance using the interrupter or impulse oscillation techniques.
