What is normal range for 6 Minute walk Test?
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 many meters is a 6 minute walk?
We measured 6MWD, height, weight, spirometry, heart rate (HR), maximum HR (HRmax) during the 6-min walk test/the predicted maximum HR (HRmax % pred), Borg dyspnoea score and oxygen saturation. The mean±sd 6MWD was 571±90 m (range 380–782 m).
What is a good 6 minute walk test result?
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.
How do you measure a 6 minute walk?
You should be given the following instructions: The object of the test is to walk as far as possible for six minutes. You will walk at your normal pace to a chair or cone, and turn around. And you continue to walk back and forth for six minutes. Let the staff know if you are having chest pain or breathing difficulty.

How do you calculate VO2max from 6 minute walk?
In model 2, VO2max could be estimated by 6MWD according to the following equation: VO2max (mL/kg/min) = –9.824 + (0.072 × 6MWDm).
What is the purpose of a 6 minute walk test?
The 6 Minute Walk Test is a sub-maximal exercise test used to assess aerobic capacity and endurance. The distance covered over a time of 6 minutes is used as the outcome by which to compare changes in performance capacity.
Is the 6 minute walk test valid?
Conclusions: The 6-minute walk is a valid and reliable method of assessing functional ability in a Phase II/III CR population. A learning effect of 6% was observed over the three walks; however, it is unknown if this learning effect will be retained over time.
What is modified 6 minute walk Test?
The 6-min walk test (6MWT) has been used to assess functional status and measure clinical outcomes in studies of patients with chronic respiratory disease. This test assesses the farthest distance that a patient can walk in 6 min.
What is the 6 minute walk test calculator?
The 6 minute walk test calculator provides reference values for the distance an adult should walk during six minutes. We use the 6 minute walk distance (6MWD) to assess a patient’s functional status, their response to therapy, and for the prognosis of different cardiopulmonary conditions.
Why do we use the 6 minute walk distance (6MWD)?
We use the 6 minute walk distance (6MWD) to assess a patient’s functional status, their response to therapy, and for the prognosis of different cardiopulmonary conditions.

Patient Instructions: “The object of this test is to walk as far as possible for 6 minutes. You will walk back and forth in this hallway. Six minutes is a long time to walk, so you will be exerting yourself. breath or become exhausted. You are permitted to slow down, to stop, and to rest as necessary.
How does the 6 minute walk test vary between pulmonary hypertension centers?
We feel that 6 minute walk test vary between institutions from conversations with personnel at other pulmonary hypertension (PH) centers. Although most centers strive to comply with the recommendations of the American Thoracic Society, certain differences are dictated by the architectural design of the test facilities.
