Electrodes

What are electrodes?

A device that converts ionic potentials into electronic potentials

Electrocardiographs do what

Record small voltages, 1mv

Disposable electrodes

Reduces cross contamination

Column electrode

Reduces motion generated by PATIENT MOVEMENT by elimimating electrode sllipage

Needle electrode EEG

Electroencephalography monitoring, fast aquisition, to reduce impedamce and movement artifact

Needle electrode ECG

Electrocardiography monitoring, extremely fast application
