Acute respiratory failure is a potentially life-threatening condition characterized by the sudden inability of the lungs to provide enough oxygen to the body's organs and tissues or to remove carbon dioxide from the blood. This can result from a variety of causes, including conditions such as pneumonia, chronic obstructive pulmonary disease (COPD), asthma, pulmonary embolism, or acute respiratory distress syndrome (ARDS). Patients with acute respiratory failure often require immediate medical intervention, such as mechanical ventilation, oxygen therapy, or medications to support their breathing and improve oxygenation. Research in this area focuses on understanding the underlying mechanisms of acute respiratory failure, improving diagnostic methods, and developing more effective treatments to improve outcomes for patients.
