Final answer:
mMRC 0-1, CAT less than 10, and CCQ less than 1 are measures used to assess breathlessness and the impact of COPD symptoms on a patient's health and daily life.
Step-by-step explanation:
mMRC refers to the modified Medical Research Council scale, which measures the severity of breathlessness in patients with respiratory diseases. A score of 0 indicates no breathlessness, while a score of 1 indicates breathlessness during activities such as walking uphill. CAT refers to the COPD Assessment Test, which assesses the impact of chronic obstructive pulmonary disease (COPD) on a patient's health status. A score less than 10 indicates low impact of COPD symptoms. CCQ refers to the Clinical COPD Questionnaire, which measures the impact of COPD symptoms on a patient's daily life. A score less than 1 indicates a lower impact of symptoms on daily activities.
