HRV biofeedback
HRV biofeedback protocol is modified from Lehrer's HRV biofeedback manual (2000), which had been successfully used to improve functioning and quality of life for patients with asthma and COPD. A noninvasive biofeedback system with a NeXus-10 with BioTrace+ (Mind Media B.V., Netherlands) and laptop computer will be used for biofeedback intervention. The intervention protocol is including paced breathing in resonant frequency, abdominal breathing and pursed-lip breathing, and visual biofeedback. The designed intervention protocol will include 8 once-a-week, individual, 20-min in hospital training sessions and twice-a-day, 20-min home self-practices.
