I was there on 8/16 for a nuclear stress test at 9:45. Forgot the technician's name. The whole experience went well however my care was very lacking. The technician didn't stay with me during the pictures (don't know if that's normal) She said she would check on my halfway into the first round of pictures. She just popped in and said I had 7 more minutes and left the room. Even though I had a blanket on me after drinking three cups of ice cold water and in a cold room. I was shivering and my teeth were chattering. When the pictures were over and she helped me sit up. I told her I hoped I was able to be still enough and explained. She then told me she could fix it. Had she asked me how I was when she "checked" on me I would've have been more comfortable during the last half. She did adjust it so the second scan went a lot better. She also started brushing her hair after she laid me down and the first scan started before she left the room. She was nice, and explained everything very well. I just thought she could have been a little more professional. Don't know if this is where I can post a complaint or if it will even to any good. But if it's not I'll like to know how I can to improve someone else's experience. Thank you.
