Breathlessness - Background information
What is it?

  • Breathlessness is the distressing sensation of a deficit between the body's demand for breathing and the ability of the respiratory system to satisfy that demand.
  • Breathlessness can be classified by its speed of onset as:
    • Acute breathlessness — when it develops over minutes, hours, or days.
    • Chronic breathlessness — when it develops over weeks or months.
