Which of the following are true of time constants?
I.Indicate lungs' ability to receive or expel air
II.Are determined by airway resistance times compliance
III.Poor compliance with normal airway resistance results in long time constant.

Question

Quizplus · Accepted Answer

The lung time constant is calculated by multiplying the airway resistance by the compliance.The time constant provides a reference regarding the lungs' ability to receive or expel gas.A short time constant is present in conditions with a poor compliance and normal resistance (respiratory distress syndrome [RDS],pulmonary hypoplasia)or a normal compliance with decreased resistance.
