MODULE 18 · CONCLUSION & ASSESSMENT
The triad completes
You now hold the respiratory systemThe organ system responsible for gas exchange (oxygen and carbon dioxide). — the airway, the respiratory membrane, the mechanics of breathing and gas transport. Here the pleuraThe double-layered membrane surrounding the lungs and lining the thoracic cavity. takes its place beside the pericardiumThe membrane surrounding the heart. and the peritoneumThe membrane lining the abdominal cavity and organs..
Why ‘probably a muscle strain’ kept coming back
A muscle strain is a reasonable first thought about one-sided chest pain that hurts on inhalation. It is not a reasonable thought about the fourth episode, and it does not produce a pleural effusionFluid accumulation between the layers of the pleura around the lungs..
Between attacks her lungs are entirely normal — clear sounds, normal gas exchange. That is the shape of serositis: an inflamed serous surface that flares and settles, leaving the organ underneath untouched.
MUSCULOSKELETAL PAIN
The chest wall itself
Reproducible on palpation, tied to movementA fundamental property of life involving motion of the body or its parts. and posture, single episode, no effusion and no fever.
PLEURITIS
The membrane around the lung
Sharp with inspirationThe process of inhaling, driven by diaphragm and external intercostal contraction., recurrent and self-limited, with transient effusion and normal lungs in between.
