Medical Research Council dyspnoea scale for grading the degree of a patient's breathlessness

Medical Research Council dyspnoea scale for grading the degree of a patient's breathlessness

• 1. I only get breathless with strenuous exercise
• 2. I get short of breath when hurrying on level ground or walking up a slight hill
• 3. On level ground, I walk slower than people of the same age because of breathlessness, or I have to stop for breath when walking at my own pace on the level
• 4. I stop for breath after walking about 100 yards or after a few minutes on level ground
• 5. I am too breathless to leave the house or I am breathless when dressing or undressing

This scale does not measure breathlessness itself, but the disability caused by breathlessness (1).
