Dyspnea Differential Diagnosis Tree

Dyspnea differential diagnosis tree

A dyspnea differential diagnosis tree helps organize a symptom with many possible causes. It begins with respiratory and circulatory instability, then separates obstructive, infectious, pleuritic, cardiac and systemic patterns. The branches are prompts for targeted history and examination, not a diagnostic protocol. Students can use the tree to practice explaining their reasoning in a case discussion. Real shortness of breath can be urgent and always requires assessment appropriate to the severity and local clinical guidance.

Perguntas frequentes

Dúvidas comuns

Why start with instability?
