Help Tammy in her fight

My sister Tammy had surgery on 9/1/22. While in surgery her abdomen and lower bowel were punctured causing a infection in her body called Necrotizing Fasciitis which is a flesh eating disorder. The infection is spreading and has caused her to go septic. They have her on a ventilator while trying to treat the infection. She is very sick and has a long road ahead of her. She is a fighter and giving it her all but her condition is very critical. Any help would be greatly appreciated while Tammy and John face this difficult time. Thank you
