Lung compliance study

Part /: If a patient generates a negative pleural pressure change of -8 cm H 2 O during inspiration, and the lungs accept a new volume of 630 mL, what is the compliance of the lungs?

Part II: If the same patient, 6 hours later, generates a pleural pressure of -12 cm H 2 O during inspiration, and the lungs accept a new volume of 850 mL, what is the compliance of the lungs?

Part III: In comparing Part II to Part I, the patient's lung compliance is

A. increasing.

B. decreasing.

Summary Introduction

To review:

Part I: The compliance of the lungs if a patient generates a negative pleural pressure change of -8 cm H2O during inspiration, and the lungs accept a new volume of 630 ml.

Part II: The compliance of the lungs of the same patient, 6 hours later, if he generates a pleural pressure of -12 cm H2O during inspiration, and the lungs accept a new volume of 850 ml.

Part III: Comparing Part II to Part I, is the patient’s lung compliance increasing or decreasing.

Introduction:

The curve between the pressure and volume, which describes the elastic strength of the lungs, allowing the inhaling of air, is called lung compliance (images). images is described as the alteration in the ration in the volume of the lung (images) for per unit change in the pressure (images). It is mathematically expressed in milliliters per centimeter of pressure of water (mimages).

Explanation

Part I: In the given question, the change in negative pleural pressure is during inspiration, and the new volume of air accepted by the lungs is .

Now, the compliance of the lung will be:

Hence, the lung compliance of the patient is .

Part II: In the given question, the change in negative pleural pressure is
