Respiratory Evaluation

Now Mom is having a respiratory evaluation to determine whether or not she needs to be on oxygen when she goes home. They currently have her on 3 liters. They have turned it down to see if her saturation levels drop ... which they did. They dropped down to the low 90s without Mom moving so it looks like we will be going home with oxygen. This we have done before the last time Mom's EF went so low ... so I am not surprised that she needs it again.
