RT Journal Article SR Electronic T1 Biphasic Capnogram in a Single Lung Transplant Recipient – A Case Report JF Respiratory Care FD American Association for Respiratory Care SP respcare.02797 DO 10.4187/respcare.02797 A1 Hardeep S. Rai A1 Justin Boehm A1 James Stoller YR 2013 UL http://rc.rcjournal.com/content/early/2013/12/03/respcare.02797.abstract AB Capnography is a graphic representation of the carbon dioxide concentration in the airways plotted against time. We report an unusual biphasic-shaped capnogram in a single lung transplant recipient. In keeping with only two prior reports of which we are aware, we ascribe the unusual biphasic pattern to differential emptying of the native and transplanted lung. This experience reminds respiratory clinicians of the value of capnometry as a monitoring tool and hopefully will heighten awareness regarding the diagnostic value of usual and unusual capnographic patterns.
