Shortness of breath, also known as dyspnea, is not simply the sensation of “running out of air.” It is often a warning sign that the body is struggling with a serious underlying health issue. According to a 2016 study in Germany, one out of every four patients admitted to the emergency department reported difficulty breathing. Though common, this symptom can be life-threatening—especially when linked to heart or lung diseases.
This article provides a comprehensive look at shortness of breath: its definition, causes, symptoms, complications, diagnosis, treatment, and prevention. We will also examine the role of oxygen concentrators in supporting breathing and clarify when oxygen therapy is medically necessary.
Dyspnea is the subjective sensation of breathing discomfort, often described as shallow breathing, “air hunger,” or chest tightness.
Key features:

Shortness of breath is not a condition to ignore. Recognizing its causes, warning signs, and complications is crucial to protecting your health. Oxygen concentrators play an important role in both hospital and home care, particularly for patients with chronic respiratory illnesses. When used correctly under medical supervision—and combined with a healthy lifestyle—they provide a vital lifeline, improving both survival and quality of life.
