RESUMEN
Tracheal intubation is one of the most important emergency techniques, and it is a key and difficult point in advanced life support training for cardiopulmonary resuscitation. Our treatment is trying to combine standard video with visual laryngoscopes for tracheal intubation teaching. Firstly, the students watch the standard video. Then, the teacher shows how to perform a tracheal intubation by visual laryngo-scope. Finally, the students practice the intubation process on the simulation device. In this way, the teach-ing process is more intuitive, easier to be mastered, more normalized and repeatable. This method is worth to be promoted.
RESUMEN
Objective To study a kind of video transformation algorithm based on FPGA in view of the present situation that the video output of X-ray equipment can not be connected to common video adapter.Methods Through the control of non-standard video signal AD sampling data read-write succession in FIFO,800 digital sampling data was output(output resolution:800?600,refresh rate:60Hz)in the period of every line of effective signal.The output module combined these data with line and field synchronized signal and transform them into standard VGA signal.Results Non-standard medical video signal could be transformed into standard medical video signal by using VHDL in normal FPGA.Conclusion The speed of this algorithm is high,and the transformation effect is clear and smooth.
