A 50 microvolt wave at a sensitivity of 5 microvolts/mm will produce what deflection on the EEG?

To determine the deflection produced on the EEG by a 50 microvolt wave at a sensitivity of 5 microvolts/mm, one must use the relationship between the amplitude of the wave, the sensitivity, and the resulting deflection on the EEG tracing.

In this case, the deflection in millimeters can be calculated using the formula:

Deflection (mm) = Wave amplitude (microvolts) / Sensitivity (microvolts/mm).

Substituting the given values into the formula:

Deflection (mm) = 50 microvolts / 5 microvolts/mm = 10 mm.

Therefore, the wave will produce a deflection of 10 mm on the EEG. This calculation accurately takes into account both the wave's amplitude and the sensitivity of the EEG system, leading to the correct understanding of the resultant tracing on the screen.
