The purpose of this study was to describe the practical knowledge possessed by registered nurses that are part of the Air Force's Critical Care Air Transport Team (CCATT) and distinguish salient features of CCATT knowledge to critical care nursing in the hospital. This research study used descriptive, exploratory methods. Twelve CCATT nurses, identified as experts, were included in the study. Data were collected using written narratives by each participant; group interviews in which nurses discussed the written narratives; and individual interviews. Data were analyzed using interpretive phenomenology. Four major themes developed from the data. The knowledge embedded in CCATT nursing included: preflight preparation, in-flight assessment and environment, characteristics of CCATT nurse, and hospital vs. in-flight nursing practice. CCATT nurses improvise and provide nursing care based on past experiences using a broad critical care knowledge base. This has led to the development of a unique body of knowledge for nursing care. The areas of assessment and preparation described by the CCATT nurses can serve as a template for the Air Force's CCATT training program and CCATT orientation checklists. This study also identified several topics for future research.

The areas of assessment described by the nurses can serve as a template for the development of educational content and assessment tools for swallowing.

The NATO litter serves as a transport device and hospital bed during all types of operations. Little is known about the skin interface pressure on this litter. The purpose of this study was to determine whether various types of padding on the litter and body position affect the peak skin interface pressure and the total body area exposed to interface pressures above 30 mm Hg at different body areas. Thirty-two subjects participated. A repeated measures design was used. The surface effect was statistically significant for all peak pressure and surface area analyses (repeated-measures analysis of variance, p < 0.01). There was a significant decrease in peak pressure and surface area between the litter and litter plus aeromedical evacuation mattress. The addition of the blanket did not significantly reduce pressures and should not be considered a pressure-reducing measure. Conversely, an aeromedical evacuation mattress should be used for all high-risk patients if feasible. Preventive measures (turning, elevating the heels) are still required.
