Needing subreddit for advice on cardiac related assistive tech and purchases

A family member has just been hospitalized with blood clots in the lungs and heart, as well as fluid retention and heart failure. she is about to come home from two weeks in ICU and will have constant hospital at home care. i was hoping to find a subreddit that could give me some advice on what i can immediately purchase to help make her life easier and make managing her health simpler. i have bought her an apple watch for a starter, and im looking into getting a shower chair, a blood pressure monitor? certain pillows, oximeters; you name it. it would be ideal if the sub was focused on smart/tech enabled devices as well.
