If one part of the respiratory system fails to function properly, it can lead to respiratory failure. Respiratory failure happens when not enough oxygen passes from the lungs to the blood, or when too much carbon dioxide builds up in the body. This can cause damage to tissues and organs and prevent or slow oxygen delivery to the body.
The respiratory system is made up of several parts, including the nose, mouth, trachea, bronchi, and lungs. Each part plays a crucial role in the process of breathing. If any part of the system fails, it can lead to respiratory failure. Some common causes of respiratory failure include:
- Diseases that affect the lungs, such as COPD, cystic fibrosis, pneumonia, pulmonary embolism, and COVID-19
- Blockages, scarring, or fluid in the lungs
- Inability to breathe properly or deeply enough
- Abnormalities in the way blood flows through the heart
- Issues with the nerves or muscles used for breathing
- Injuries to the chest
Symptoms of respiratory failure can include shortness of breath, a bluish tint in the lips and face, confusion, and arrhythmia (irregular heartbeat) . If someone experiences these symptoms, they should seek immediate medical attention. Treatment for respiratory failure depends on the underlying cause and may include medicines and procedures to address the issue.
