EKG Acquisition第 51 / 100 题
A technician is setting up 5-lead telemetry monitoring. Which placement follows the standard color convention?
a.White on the right shoulder, black on the left shoulder, green on the right lower abdomen, red on the left lower abdomen, brown on the chest
b.White on the left shoulder, black on the right shoulder, red on the right lower abdomen, green on the left lower abdomen, brown on the chest
c.All five electrodes across the upper chest in a row
d.White and black on the legs, red and green on the arms, brown on the back
解析
The standard 5-lead convention is white on the right upper chest, black on the left upper chest, green on the right lower chest or abdomen, red on the left lower chest or abdomen, and brown as the chest lead, remembered as white on right, smoke over fire, and clouds over grass. Swapping white and black reverses lead I. Clustering the electrodes together or moving them to the limbs destroys the intended vectors.
