Effect of Triflow Breathing Training

The participants were asked to be seated comfortably and raise their heads by 30° with the guidance of the investigator. During the inspiration process, the participants' abdomens bulged. They then held their breaths for 5 seconds before exhaling from their mouths for twice the duration of inspiration. Breath training was performed five times each hour throughout the three-hour duration of each dialysis session. In sum, the experimental group performed Triflow breath training 15 times during each dialysis session. The experimental group and the control group were randomly assigned by a coin toss.
