As a medical professional, I can provide you with information on the signs and symptoms of respiratory failure. Respiratory failure occurs when the respiratory system is unable to maintain adequate oxygen levels in the blood or remove carbon dioxide effectively. Here are the common signs and symptoms: 1. Difficulty breathing or shortness of breath, especially when active. 2. Coughing up mucous. 3. Wheezing, which is a high-pitched sound when exhaling. 4. A bluish tint to the skin, lips, or fingernails, which can be a sign of low oxygen levels. 5. Rapid breathing, also known as tachypnea. 6. Fatigue, which can be a result of the body's struggle to get enough oxygen. 7. Anxiety, which may be due to the feeling of not being able to breathe properly. 8. Confusion, which can occur as the brain is also affected by the lack of oxygen. It's important to seek immediate medical attention if you or someone you know is experiencing these symptoms, as respiratory failure can be life-threatening. read more >>
