Have you ever been given the 3 minute step test?
I know that many with PH have had the 6 minute walk test, including myself. I have also had different variations of this with pedaling a stationary bike and having my oxygen levels, heart rate, and lung function monitored for breathing patterns. This last visit yesterday at my PH clinic, they did the 3 minute step test. I was really short of breath after as they monitored my lung function with activity, oxygen levels, and heart rate. Within that short amount of time my oxygen dropped in the mid 80s. I was able to complete the test but not without shakiness afterwards and a hard time getting my breath and feeling some strength back in my body.
This test made me realize the importance of wearing my oxygen with any level of activity that I’m doing. My doctor told me that it is most likely due to the filling of the heart and the output not being enough with the activity that I’m doing to give the cells the oxygen that it needs.
I am curious if there are others who had this test done called the 3 minute step test? What were your oxygen levels like during this test? Did you feel symptomatic after or during it?
