Understanding Emphysema: Causes, Risks, and Management
Emphysema is a progressive lung disease damaging alveoli and impairing oxygen exchange, leading to serious complications like heart failure and pneumothorax. Management includes oxygen therapy, lifestyle changes, and surgical options. Prevention through smoking cessation and avoiding irritants is crucial since the damage is irreversible. Early diagnosis and proper treatment can improve quality of life and prevent severe outcomes.

Understanding Emphysema: Causes, Risks, and Management
Emphysema is a chronic lung condition characterized by damage to the alveoli—the tiny air sacs where oxygen exchange occurs. When these structures deteriorate significantly, it impairs gas transfer, leading to reduced oxygen levels in the blood, a condition known as hypoxia. If traditional treatments like bronchodilators and steroids are ineffective, Long Term Oxygen Therapy (LTOT) becomes necessary. For LTOT, patients typically inhale oxygen-rich air containing 25-28% oxygen for at least 15 hours daily through nasal prongs to maintain safe oxygen saturation levels.

Potential Complications
Chronic low oxygen levels trigger a series of reactions in the body. To compensate, the heart increases output and produces more red blood cells, but these measures may become insufficient as the disease advances. This can lead to cor pulmonale, a condition where the right side of the heart enlarges due to increased pressure in the lungs (pulmonary hypertension). Over time, this strain can cause right-sided heart failure, potentially resulting in death.
