I found Dr. Brady (correct name?) and Dr. Sundar very helpful and pleasant to deal with; it's not their fault that the system is overloaded (see previous comment).

Took the concept of poor listener to a whole new art for. Then based the rest of the visit on what he thought he heard which in nd itselt e was totally illogical.

Dr. Jasper was an excellent listener, and Coordinating Nurse (ooops senior-moment, was it Kimberly?) was very personable and efficient. Dr. Sundar seemed to have confidence in my plan to start back on CPAP at low pressure to insure mucous membranes do not burn again.
