Unlock the science behind breathing and how doctors measure chest movement.
This edition presents a clear, step‑by‑step look at how respiration works in health and in disease, with practical explanations of the chest‑measurer and related diagrams.
This volume compiles the author’s methods, discoveries, and illustrations that reveal how the chest moves during ordinary and deep breathing. It explains why observing respiratory motions matters for diagnosis and how a simple instrument can capture precise changes in chest movement.
- How the chest expands during different kinds of breathing and what that reveals about health.
- How a pocket‑sized chest‑measurer works and what its readings mean for respiration.
- Descriptions of the rib groups and how different parts of the chest contribute to breathing.
- Cutting‑edge visualization methods, including diagrams and daguerreotypes, to show breathing mechanics.
Ideal for readers curious about medical history, respiratory science, and how clinicians approach chest disease with careful observation of movement and form.
