Hyperbaric chamber for Humberto

My name is Elizabeth Gaona about ten years ago my dad was diagnosed with diabetes. His name is Humeberto Salas , he was able to control it for a while so after that he didn't really pay attention. Two years ago he got an affection on his foot , they had to cut part of his foot. Three weeks ago I was at work , my mother called and told me my dad was in the hospital. I headed down there , I spoke to the doctors. They told me things had gotten worse. That Sunday he went into surgery, the doctor didn't cut more fingers but he did have to cut a part of his bottom foot. They said they would try to stop the infection to spread to the bone . They told him the only way to stop the infection from spredding was having hyperbaric therapy. We're a low resource family. We would really appeciate it if y'all could help us out .
