A 6-minute walk test (6MWT) is a standardized test that measures how far you can walk in exactly 6 minutes while monitoring your oxygen levels. It's performed in a clinical setting and helps doctors evaluate your exercise capacity and functional status. The test provides specific data about your six-minute walk distance (6MWD) which helps determine PAH severity and treatment decisions. While both tests measure oxygen levels during activity, ambulatory oximetry allows for monitoring during your regular daily activities rather than in a controlled clinical environment. The 6MWT provides additional standardized measurements beyond just oxygen levels, including blood pressure, heart electrical signals, and a specific distance measurement that can be compared across different test sessions to track your PAH progression and help guide treatment choices.
