    Dr. Sundar was very sympathetic and stated he understood the difficulties with CPAP. He didn't make me feel bad about having difficulties with my CPAP but he encouraged me to try again.

    He was fine...the things he explained that I had a difficult time with were just wrapping my brain around what he said and comprehending it

    UH HOSPITALS AND CLINICS

    This was a 6-mo followup for CPAP usage with high event numbers in spite of interim adjustments to CPAP settings. Dr. Sundar is always comprehensive in reviewing my current health considerations, and proactive in addressing changes / potential problems. He had already reviewed the interim changes and results. He explained why he was choosing one of two options to address indications of central apnea. He then went about laying the groundwork for additional heart-related testing and provided detailed background to my PCP who will pick up the coordination. He could not have been more consummate in his caring and attention to my needs.
