Acute respiratory distress can be caused by all EXCEPT:

Acute respiratory distress can indeed be caused by various factors that directly affect the respiratory system or impinge upon its function. Trauma can lead to situations where the lungs or the airways are damaged, resulting in impaired gas exchange and acute distress. Obstructive sleep apnea contributes to respiratory distress by intermittently blocking airflow during sleep, leading to oxygen deprivation. Chronic obstructive pulmonary disease (COPD) represents a group of progressive lung diseases, where chronic inflammation and obstruction lead to breathing difficulties and, in acute exacerbations, can heighten respiratory distress.

However, hypothermia does not directly cause acute respiratory distress in the same manner as the other listed conditions. While hypothermia can lead to multiple systemic complications and affect the respiratory drive, it is primarily a decrease in body temperature rather than a direct pathology of the respiratory system. Therefore, while individuals experiencing severe hypothermia may exhibit altered respiratory patterns, hypothermia itself is not classified as a direct cause of acute respiratory distress like the other conditions mentioned.
