What is the Six Minute Walk for COPD?
The 6-minute walk test for COPD is a simple way to test how your heart and lungs respond to light exercise. During the test, you’ll be monitored while you walk at your usual pace for 6 minutes. The results might lead to more testing or to a treatment plan.
How do you know what stage you are at with COPD?
Your physician will determine your stage based on results from a breathing test called a spirometry, which assesses lung function by measuring how much air you can breathe in and out and how quickly and easily you can exhale. They will also consider the severity of your symptoms and the frequency of flare-ups.
How long is each stage of COPD?
Stage 1: 0.3 years. Stage 2: 2.2 years. Stage 3: 5.8 years. Stage 4: 5.8 years.
How far can a normal person walk in 6 minutes?
Results. The average 6MWD was 659±62 m (range 484–820 m). Males walked 59±13 m further than females ( ). Height ( , ), weight ( , ) and FEV1 ( , ) were significantly correlated with 6MWD.
What is a good score for the 6 minute walk test?
Although the MID varies slightly depending on the test method and study population, the available evidence suggests that it is about 30 m. A 2019 article notes that doctors can use 6MWT scores to predict the severity of lung conditions or the likelihood that they will be fatal.
What is a good number for a six minute walk?
Moreover, the 6MWT better reflects activities of daily living than other walk tests. Recently, the American Thoracic Society developed guidelines for the 6MWT in clinical settings. In healthy subjects, the 6-min walk distance (6MWD) ranges from 400 to 700 m, the main predictor variables being gender, age and height.
How long does it take to get to stage 4 of COPD?
End-stage, or stage 4, COPD is the final stage of chronic obstructive pulmonary disease. Most people reach it after years of living with the disease and the lung damage it causes. As a result, your quality of life is low. You’ll have frequent exacerbations, or flares — one of which could be fatal.
What is a good result for the 6 minute walk test?
Six MWD <300 m is an adverse prognostic indicator in PAH. Conversely, 6 MWD >400 m is considered a favorable prognostic indicator. Most studies that have included patients with severe PAH (mean pulmonary artery pressure >45 mm Hg) have reported baseline 6 MWD <300 m.
What is a good score for the Six minute walk test?
What might the results show?
| Reading | Performance |
|---|---|
| under 5 METS or inability to exercise for 6 minutes or raise the heart rate to 85% of maximum | poor |
| 5–8 METS | fair |
| 9–11 METS | good |
| 12 METS or more | excellent, any score above 10 METS suggests a 5-year survival rate of 95% |
