چکیده
Abstract Purpose For this study, we aimed to compare dynamic hyperinflation measured by cardiopulmonary exercise testing (CPET), a six-minute walking test (6-MWT), and manually paced tachypnea (MPT) in patients with severe emphysema who were treated endobronchial coils. Additionally, investigated whether changed after treatment Methods Dynamic was CPET, 6-MWT, an MPT 29 before coil treatment. Results There no significant change Comparison of CPET showed strong association (rho 0.660, p < 0.001) moderate agreement (BA-plot, 202 ml difference favor MPT). only the 6-MWT 0.361, 0.024). Conclusion can be suitable alternative measure but may overestimate possibly due higher breathing frequency.
