Effects of a First Responders Automatic External Defibrillator (AED) program on patient Outcomes in a Rural Emergency Medical Service System

Background For patients in cardiac arrest the most important variable in survival is rapid activation of emergency medical services to provide early defibrillation. Previous studies have indicated that for the greatest chance of survival the patient must be defibrillated within six minutes of collapse. In September of 2002 the Fairmont police department placed AED\u27s in the medical kits of their officers in an effort to improve the chances of survival for the cardiac arrest patients in the city. This study is an attempt to gauge the success of this AED program by Iooking at multiple variables in the care of cardiac arrest patients. Methods A retrospective chart review study was undertaken and data was captured from patient care documents. An equal number of cardiac arrests (18) were taken from before and after the AED program was initiated for a total of 36 patients in the study. Results Statistical significant was found in the time from 911 dispatch to defibrillator placement and analysis,3.4 min in the pre-AED group vs. 5.2 min in the post AED group (P=0.03). No significance was found in patient outcomes in comparison to the pre-AED period Discussion Although there was no change in the patient outcomes after the AED program was initiated, a closer look at the data shows that a decrease in the amount of time it took to get to the patients side was accomplished, given more time and data points, it is possible that an increase in patient survival might be seen. Focus for the next study would be an attempt to decrease the time from collapse to patient defibrillation

Understanding High Recession Rates of Carbon Ablators Seen in Shear Tests in an Arc Jet

High rates of recession in arc jet shear tests of Phenolic Impregnated Carbon Ablator (PICA) inspired a series of tests and analysis on FiberForm (a carbon preform used in the fabrication of PICA). Arc jet tests were performed on FiberForm in both air and pure nitrogen for stagnation and shear configurations. The nitrogen tests showed little or no recession, while the air tests of FiberForm showed recession rates similar to that of PICA (when adjusted for the difference in density). While mechanical erosion can not be ruled out, this is the first step in doing so. Analysis using a carbon oxidation boundary condition within DPLR was used to predict the recession rate of FiberForm. The analysis indicates that much of the anomalous recession behavior seen in shear tests may simply be an artifact of the non-flight like test configuration (copper upstream of the test article) a result of dissimilar enthalpy and oxygen concentration profiles on the copper. Shape change effects were also investigated and shown to be relatively small
