6 minute walk test

What is a 6 minute walk test?

A “6 minute walk” test is a simple procedure performed to give us accurate information about your blood oxygen levels whilst you exercise.

Why do I need to have this test?

This test can be used to determine your exercise capacity and whether you need additional oxygen when you are exercising. In some situations, the 6 minute walk test provides better information of a patient’s ability to perform daily activities.

What happens during the test?

Before the test begins the Physiologist will explain the test to you in detail and will answer any questions that you have.

A probe will be put on your ear. This will provide us with information about your blood oxygen levels. You will then be asked to walk for 6 minutes along a flat corridor.

The test will take approximately half an hour to complete. The length of the test may vary slightly depending on your oxygen levels during the test..

Important information

• Please do not wear nail varnish to your appointment.
• Please bring any walking aids (stick etc.) that you regularly use when walking and any oxygen prescribed to you for use whilst walking outside the home.

Thank you for your cooperation. This will assist us in obtaining accurate information and enable us to provide you with the most appropriate treatment.
