Define microshock.
|
MIcroshock is defined as the passage of current through intracardiac conductors i.e. cardiac catheters. Ventriicular fibrillation may result at currents lass than 100 uV.

|

|
300 Microamperes (uA)

List precautions to protect patients from electrical shock.
|
Use 3 prong plug.
Plug all power cords from all equipment touching the patient into the same receptacle. Never use an extension cord. Make sure all equipment attached to athe patient has a current safety inspection sticker. Remove 2-prong plug devices (radio, clock) from the patient's room. Turn on the EEG instrument before attaching electrodes. Disconnect the patient before turning the EEG instrument off. |

Define macroshock.
|
Macroshock is the passage of current from one part of the body to another. The lethal macroshock current resulting in ventricular fibrillation must exceed 100 to 300 ma.
