When mom gets hurt, how many times a day will Medicare,Tricare, & Medicaid allow a caregiver to come to the house and help with her needs?

Several times a year my 97 year old mom falls, trips, or hurts herself in other ways, and is barely able to get up, if at all, and do things for herself. She has medicate and Tricare. I live with her in Florida and I’m on disability. Our combined income is @ $3000. When she gets hurt, it puts a huge burden on me, because I have serious health problems and have a difficult time getting around and taking care of everything. Would MEDICARE or Tricare or Medicaid pay for someone to come help her, and if so, what’s the maximum visits per day or week? I’m desperate to know because I just spent 6 weeks waiting on her constantly at my own health’s expense. Every time this happens (several times a year) the mental and physical stress and strain wipes me out and I’m barely able to take care of myself, and suffer setbacks. I’m ruining my own health to help mom and it’s not a good situation. Thank you for any info anyone can provide.
