Question
Chapter 2, Problem 2CAQ3
Summary Introduction
To review:
The description of the two major tracheobronchial tree changes that occur during an asthma attack that caused gas flow to significantly decrease.
Introduction:
The Hagen–Poiseulli equation explains the dynamic characteristics of lungs with reference to the lung–chest compliance. The pressure and movement of air inside and outside the lungs are important for the body. The changes that occur in the tracheobronchial tree during an asthma attack are described by Poiseulli’s law.
Please refer to Clinical Application Case-2 for further information.
