Case 1

Because this patient's ribs were broken on the right side, his right chest (bulged outward _____; caved inward_____) during each inspiration.

To review:

The blank space in the statement, “Because this patient’s ribs were broken on the right side, his right chest (bulged outward__________; caved inward _______) during each inspiration.”

Introduction:

Inspiration is the process of exchange of gases between atmospheric pressure and pressure inside the alveoli. It involves the contraction of various muscles, diaphragm, and intercostal muscles present in the chest region. Major chest injury can result in the unstable chest wall and leads to difficulty in breathing.

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

Explanation

Lungs and chest wall work together during inspiration and expiration process. The moment air is breathed in, the chest wall moves outward and lungs move inward. They work against each other with the help of muscles and bones of the thorax. It can be measured by lung compliance. The patient’s ribs were broken from right side and get separated from the chest wall due to some accident. The patient inhales the air, the transthoracic transpulmonary and pressure gradients affect the broken ribs to curve inward during each inspiration...
