Very sorry to hear of your wife’s precarious situation . VERY !
I was in your shoes twelve years ago and I PRAY your wife has a better outcome . Do all you can to make sure ICU nurses and doctors are truly attentive to your wife . I will say no more – in my wife’s case , lack of attention to monitored vital signs ultimately resulted in her death a day later.
I hesitated to even say that , with all you are dealing with , but if it helps save your wife’s life then it is worth watching their activities closely .
