chest x-ray coupled with neurological exam

I posted a question earlier (see Below) I forgot to ask about my chest x-ray showing "flattening of the hemidiaphragms". I have never heard of this. Also I asked earlier about my neurological exam - all this was done at the UK Pulmonary Clinic. All these findings are on his report that was submitted to Soc Sec for my disability claim. His finds were as he listed them: 1. COPD 2. Chronic Respiratory Failure

It is that I don't understand what "grossly intact" means. Thank you for your help with this.

The report stated that my neurological exam was "grossly intact". I cannot find what this means. Any ideas? Also one of his findings was "chronic respiratory failure". Not exactly sure what this means but it does not sound good. Please help. I have MS which was diagnosed in the mid-90's.
