Case 1

The pathophysiologic process that developed in this case was corrected with______. During each breath, the patient's chest wall (caved inward_____________; moved outward __________) and then returned to normal ___________at the end of each expiration.

Summary Introduction

To review:

The blank space in the statement, “The pathophysiologic process that developed in this case was corrected with ________. During each breath, the patient’s chest wall (caved inward __________; moved outward_________) and then returned to normal ________ at the end of each expiration.”

Introduction:

A normal lung functions as a result of chest wall compliance and lung compliance. The lung, or pulmonary, compliance of an individual is an estimate of the capacity of the lung to stretch and expand. The elastic forces operating between the chest wall and lung can be measured by lung compliance. When the relationship between the lung and chest wall gets disturbed by any trauma or injury, it affects the elastic forces, causing a decrease or an increase in lung compliance.

Please refer to Clinical Application Case-1 for further information.

Explanation

In the given case, the patient, who met with a motorcycle accident, was admitted to the intensive care unit. He had broken ribs and several abrasions and lacerations on his face, neck, and shoulder. He had a flail chest (the right anterior part of chest moves inward during inhaling and outward during exhaling) also. He was immediately put on a mechanical ventilator with positive pressure, so that he does not need to produce a negative pressure to breathe in.

A flail chest is caused by more than one rib fracture in the lungs. This causes an imbalance in the pressure gradient and the chest wall curves in during inspiration. It also affects the alveolar gas exchange that results in a collapsed lung. The patient becomes susceptible to other diseases, like secondary pneumonia...
