Wear comfortable clothing and shoes for walking.

Use usual walking aids.

No vigorous exercise should be performed within 2 hours.

Repeat testing should occur at the same time of the day to reduce intraday variability.

When possible, perform PFTs prior to the 6mwt.

Oxygen should be administered as prescribed by the physician or protocol; oxygen flow should remain constant throughout the test. Oxygen is not to be titrated during the test; if titration is needed, this should be done as a separate test before the 6mwt and adequate rest (at least 15 min) should be allowed after exercise titration before the 6mwt.

Medications should be taken as prescribed.

Pretest assessment should include resting SpO2, heart rate, blood pressure, and baseline dyspnea and fatigue (modified Borg scale).
