Acronym for "Modified Medical Research Council Scale"
The MRC-Scale can be used as a score to assess the respiratory distress in chronic obstructive pulmonary disease (COPD).
The scaling is done in 5 steps:
- 0 = shortness of breath only in case of exceptional stress
- 1= Difficulty breathing when climbing stairs, going uphill
- 2 = difficulty in breathing when walking on the level
- 3 = Patient must stop after 100m due to shortness of breath
- 4 = Difficulty breathing when dressed and undressed, patient is too short of breath to leave the house.
The MMRC scale is used in the GOLD classification of COPD severity.
