Using Skin Blood Flow to Measure the Effect of Different Doses of Negative Pressure Therapy

"We designed the experiment based on current clinical cases involving negative pressure therapy (NPT) for wounds and related animal studies. In this study, we applied three levels of negative pressure: -105 mmHg, -125 mmHg, and -145 mmHg, each for 10 minutes.~The -125 mmHg dosage was chosen based on findings from a previous study. Similar studies that utilized increments and decrements of 20 mmHg informed our research.~Moreover, to prevent any damage to new capillaries, we established a base dosage of -125 mmHg and refrained from using negative pressure levels exceeding -150 mmHg."
