The critical care department to be studied contains 20 beds that are used for a mix of level two or three care depending upon patient need and nursing staff capacity. Of these beds, 15 are split almost equally into two orientations. A plan of each orientation will be divided into nine sections to correspond to a bagua panel. Each item of equipment will be assigned a feng shui element based upon its shape or colour. Using a bagua, the feng shui of each bed space will be mapped. For each bagua panel a +1 will be awarded for each piece of equipment that positively influenced chi either directly or indirectly through the nurturing cycle. Conversely a -1 will be awarded for each piece of equipment that negatively influenced chi either directly or indirectly through the destructive cycle. The points awarded in each panel will then be added together to give a feng shui score for that panel. The feng shui score will be limited to -5 and +5. This score will then be converted to a 0-10 'chi score' for nurse self-assessment and to allow data analysis.
