my fiancé has recently went downhill fast made progress and fallen again, here's the story she has pcos and recently was hospitalized for having bilateral nomonia, bronchitis and tonsilitis which sent her into raspatory failure she has been doing better and one day she checked her 02 and it was 55 so we rushed to the hospital and they thing she might have copd her o2 has gotten as low as 44 and ik that really dangerous so my question is at what point can i wake her up her doctor said that this can cause her body to rely on me but on the other hand i have nurses telling me if she gets to low its ok to wake her up, she is also on oxygen again currently at 4 literes
