You may want to try a different speed in your next qigong experiment. Patients should move as slow as a giant tortoise so that blood won't rush to hands and feet. If patients cannot do deep breathing, they should wear oxygen masks. These are based on my new theory on slow Taichi posted in my Google Plus account under my name Pao Yen. I don't do qigong but I see that some of them are good deep breathing exercises. I still believe that taichi has a better mechanism to send blood to capillaries of all internal organs including brains in a 25 minute taichi long form set, which forms the basis of self-healing.
