“In addition to chapters on equipment, Anesthesia Equipment covers other equally important topics such as ergonomics, display technology, and the future of the equipment. It’s got some really unique features that aren’t covered in other texts.” – Dr. Jan Ehrenwerth 

What Makes Anesthesia Equipment, 2nd Edition Unique?

The other editors and I first became involved with Anesthesia Equipment because we felt that there wasn’t a good anesthesia equipment book that appealed to a broad audience. There were books that were either very simple or very technical. We felt that we could do a better job. We spent a lot of time making the original edition very readable and we hope we’ve accomplished the same thing with this edition. We’ve updated it tremendously. Anesthesia Equipment is the first book on the topic that’s in full color and that covers the whole field. In addition to chapters on equipment, the text covers other equally important topics such as ergonomics, display technology, and the future of anesthesia equipment. It has some really unique features that aren’t covered in other texts.

Why Did You Go Into Anesthesiology?

I always had an interest in the field of health care and my natural interest in science led me to medicine. I became interested in anesthesiology because I met a very influential anesthesiologist. At the time, there were summer programs sponsored by the American Society of Anesthesiologists that enabled medical students, to spend two months doing anesthesia.  I ended up spending the summer in Dr. Rick Siker’s Department of Anesthesiology, at Mercy Hospital in Pittsburgh. He was a very prominent anesthesiologist, who went on to become the President of the American Society of Anesthesiologists. He got me interested in anesthesiology, and during my residency sparked my interest in learning about anesthesia equipment

Emerging Areas of Anesthesiology

I think information technology in anesthesia is playing a bigger role in the field. In some ways, it’s being put to use very well, and in some ways it’s inhibiting our practice, but it’s an evolutionary process. The integration of monitoring and recordkeeping is emerging as a new area. The equipment that we’re using is getting more electronic and more user-friendly. Initially, some of the electronic equipment was not very user-friendly, but I think that we’re showing some really good progress in that area.
