Campbell Diagram

Abnormalities of pulmonary mechanics [e.g. pulmonary edema, pneumonia] are depicted by shifts in the curve labeled 'static pulmonary properties' whereas abnormalities of chest wall mechanics are depicted by shifts in the curve labeled 'static chest wall properties' [e.g. ascites, obesity]. Abnormalities of airways resistance are marked by changes in the curve labeled 'dynamic respiratory properties' [e.g. COPD exacerbation].

A graphical means of assessing the relationship between intra-thoracic pressure or pleural pressure [on the x-axis] and thoracic volume [on the y-axis] as a function of airway resistance, lung compliance and chest wall compliance.

Heart-lung.org will provide a comprehensive, on-line tutorial in cardiovascular and respiratory physiology for the interested medical student, resident and fellow.

- ABOUT -

- FORMAT -

The first 4 chapters will cover basic physiology and pathophysiology with an emphasis on the Campbell and Guyton Diagrams.

The remaining 4 chapters will focus on clinically-relevant topics in the intensive care unit; the discussions will be largely drawn from the physiology covered in the first half of the textbook.
