Because so many different conditions can trigger breathing problems, the symptoms also are varied. Individuals should promptly consult with a physician after experiencing any of the following symptoms:

• Unexplained shortness of breath
  
  
• Wheezing (a whistling or high-pitched sound when breathing)
  
  
• Shortness of breath after mild activity
  
  
• Dizziness or confusion
  
  
• Waking up short of breath, or using extra pillows to prop up the head as a means of avoiding shortness of breath
  
  
• Barking, croupy cough or tightness in the throat
  
  
• Hyperventilation (breathing more than the body needs)
  
  
• Significant or continuous cough
  
  
• Fever associated with breathing problems
  
  
• Gurgling sounds coming from the chest

Immediate medical attention should be sought when breathing problems seriously interfere with breathing or when breathing completely stops. Individuals should also seek emergency medical attention when breathing problems are accompanied by:

• Chest pain
  
• Sweating
  
• Nausea or vomiting
  
• Bluish lips and fingernails (cyanosis)
  
• Inability to speak
  
• Swelling of the face, tongue or throat
  
• Hives
  
• Rapid or irregular heartbeat
  
• Coughing up large amounts of blood
