Hi, I take care of my 85 year old mom. Pretty much by myself. She has home health but that's only a nurse visit and a little pt. She has non small cell cancer that has been treated with 10 visits of radiation. She goes back in April for another pet scan. She also has copd, CHF. She has badly damaged lungs that's even more so since the radiation. Her oxygen levels are dangerous when she sleeps at night , she wears oxygen 24/7. But mornings it has fallen into 50,s level. Last night her oxygen was off to shower. She became out of breath and I got her out. Checked 02 level it was 51. Her Dr is useless , her doesn't get it. She recently got out of hospital because she had quit breathing at home and I called 911. 02 level was 57 and she was unconscious. She was on ventilator for 2 days. Had phemonia that was antbiotic resistant. In isolation. I don't know each morning if she's going to wake op or be dead. Scares me to death. How do you deal with the stress of it.???
