In Koharu's treatment, he comprehensively evaluates respiratory status, secretions, signs of infection, nutritional status, muscle tone, sleep, pain, and discomfort. Since Koharu has difficulty speaking, he treats eye contact, expressions, vocalizations, physical reactions, and deviations from her usual state as vital information.

He collaborates with the family and home care nurses to support Koharu in living safely and comfortably at home.
