Background: Self-care systems for early-stage specialist palliative care for cancer patients and their family caregivers have received much attention recently. Resonant breathing is an established method for maximizing heart rate variability (HRV), but it has not been implemented for home self-care. Objective: We aimed to examine the usefulness and ease of implementation for family caregivers to administer resonant breathing using a portable device at home.
