This paper studies the validity of the POWERbreathe KH1 - a recently introduced, handheld, electronic loading device. It looks at how well it provides automatically processed information on external inspiratory work, power and breathing pattern during loaded breathing tasks in patients with COPD.
“The handheld device provides automatically processed and valid estimates of physical units of energy during loaded breathing tasks. This enables health care providers to quantify the load on inspiratory muscles during these tests in daily clinical practice.”
