Final answer:
Pleural effusions can be influenced by increased airway resistance, thoracic cavity puncture, and fluid buildup in body cavities.
Step-by-step explanation:
Pleural effusions occur when excess fluid accumulates in the pleural cavity, the space between the two layers of tissue that line the lungs and chest wall. The three factors that have a prediction in regards to pleural effusions are increased airway resistance, a puncture to the thoracic cavity, and fluid buildup in one of the body cavities.
Increased airway resistance can cause an increase in pleural pressure during inhalation. This can lead to increased fluid leakage into the pleural cavity, resulting in a pleural effusion.
A puncture to the thoracic cavity can disrupt the negative pressure in the pleural cavity, leading to a collapsed lung and the development of a pleural effusion.
If fluid builds up excessively in one of the body cavities, it can increase the risk of developing a pleural effusion.
