ARD, or Acute Respiratory Distress, is a serious medical condition characterized by sudden and severe difficulty in breathing. It occurs when the lungs become inflamed and filled with fluid, making it hard for oxygen to enter the bloodstream. Common causes include pneumonia, sepsis, and trauma. Treatment for ARD typically involves supportive care, such as oxygen therapy and mechanical ventilation, to help patients breathe. Early diagnosis and intervention are crucial for improving outcomes. Healthcare providers often monitor patients closely to manage complications and ensure proper recovery.
