r. My moms carbon dioxides levels were very high and they think she might have taken a double dose of valum and sleeping meds and went to the hospital, and is on a ventilator. They lower her sedation every morning and try to get her to blink, stick her tongue out, and squueeze her hand and when they cant they resedate her and try again the next day. She has lung issues. But has always been fine. They need to unsedate her and take her off the vent and let her body wake up but they wont take her off bc of the carbon dioxide level. Anyone know what is wrong? Drs are playing guessing games its awful. My mom cries and open her eyes at me. She is miserable and cant communicate but i know she is there. It is breaking my heart. Any advice would help.
