Abstract
Cardio-pulmonary bypass (CPB) involves the maintenance of whole body perfusion during cardiac surgery. While CPB is safe, emergencies do occur and perfusionists are expected to respond appropriately. However, perfusionists' training programs appear to be underdeveloped. In addition, there appears to be little understanding about how perfusionists conceptualise their work domain. This paper presents a work domain analysis-based (WDA) protocol for analysing perfusionists conceptualisations. A WDA of the CPB is presented. A hi-fidelity simulation environment with a video-cued recall interview data collection protocol is described and a Markov Chain analysis of verbal protocols is outlined using two participant data sets. We conclude that with further participant data analysis this novel approach offers promising insights into conceptualisation processes and exposes addition procedural, organisational and engineering issues that may need to be included in curriculum development.
