Please help with my moms medical

My mom got a bad infection called necrotizing fasciitis. They put her on a ventilator and did two surgeries. They said the infection went to her organs and shutting them down. It has been over a week they don’t think she can make it w/o a ventilator. Moms wishes is to be cremated. She has no life insurance so asking for a little help thru this hard time.
