Analysis of 2004 German general aviation aircraft accidents according to the HFACS model.
The number of aircraft accidents remains on a constant level since the late 1990s. Routine analysis in detail of the causative factors is not carried out in Germany. The analysis of flight mishaps has been demonstrated to be an important basis for flight safety. The Human Factors Analysis and Classification System (HFACS) model is best suitable for aircraft accident analysis. The aim of this study was to classify aircraft accidents in the General Aviation (GA) of Germany according to the HFACS model and to figure out the underlying causes. ⋯ Our data mainly seem to be in concordance with previously published data on GA. An improvement of flight safety can be achieved only with a detailed analysis of the accident data. Therefore, more data on aircraft accidents in Germany are needed, for example, by adapting the German aircraft accident report form. Pilots should train in approaches and landings to conduct a higher level of proficiency.

Feasibility of preclinical cardiac output and systemic vascular resistance in HEMS in thoracic pain--the ultrasonic cardiac output monitor.
Cardiac output (CO) and systemic vascular resistance (SVR) are important hemodynamic parameters in emergency patients and for clinical early goal-directed therapy. This study evaluated the feasibility of CO and SVR determination using preclinical continuous wave Doppler ultrasound in a helicopter emergency medical service (HEMS) on emergency patients presenting with or without thoracic pain as a pilot observational study. ⋯ Determining SV, CO/CI, and SVR in different emergency situations in HEMS using rapid CW Doppler ultrasound is feasible. Thoracic pain patients have increased SVR and lower CO/CI and reduced aortic minute distance than do non-thoracic pain patients in the preclinical setting.
