Saturday morning with Ralph

I'm just sitting here in Ralph's room watching him and watching the monitors. I like the quiet so I keep the TV turned off. I've had to bump up his oxygen to 3.5 liters to keep him above 90%. It's kind of disappointing and I don't know what is going on. Maybe the gunk in his lungs is breaking up? Maybe he is just sleeping very deeply?

OK...I just found a bottle on the floor. I remember the nurse giving him his meds in a bottle of milk this morning. I don't remember hearing a bottle hit the floor. Could it be that he didn't get all his medicine? She said she was giving potassium and lasix but she didn't say anything about his Sildenafil. Hmmm. I must be off my game. I usually watch the medication schedule like a hawk.
