The Forgotten Test

So the folks from nuclear medicine did not have Mom on their list though I do not know how. Anyway they packed up and went home around 7pm or so. I had been asking "when is the test?" about a hundred times then finally someone started checking. They ended up paging the doctor in charge of the nuclear medicine team and they caught him driving home. True to his word he called back as soon as he got home and made arrangements for Mom to have this test tonight. So she is supposed to have the test any minute now (we will see). Currently she is having her second EKG which will hopefully go just fine. Her sat levels keep going down which concerns me. They are still in the 90's but she is on a lot of oxygen 15 liters so it should be at 100% most of the time. Man ... I want to get this test done NOW!
