Dyspnea is translated from medical terminology to mean difficult breathing, where some disease, reaction, or other stimulant has caused breathing to be obstructed or otherwiseâ¦ uneasy. Apnea means lack of or stopped breathing.
Dyspnea comes from the Latin word âdyspnoeaâ which means shortness of breath. It is associated with diseases in the respiratory and cardiovascular system. Normally, our body regulates our breathing via the medulla oblongata in the brainstem. Dyspnea is also experienced when resting or exerting an effort especially when doing an activity. Dyspnea is also classified into chronic and acute.
