Capacitor Discharge Tool
A capacitor discharge tool is used to discharge the energy storage capacitor (see Capacitor Discharging
Procedure (p. 178)) and the pacing capacitor (see Discharging the C15 Pacing Capacitor (p. 179).
The illustration shows how the biphasic capacitor discharge tool is constructed. The materials used in
this example are:
• 10 k, 2 W resistor (ten 1 K 2 W), high-voltage
• 5 M, 5 W resistor, high-voltage
• Neon lamp, NE76, NE2, or NE2H
• 8 AWG copper wire
• Clear plastic tubing, capable of insulating 10 kV
• 10 kV insulation
• RTV silicone rubber sealant
DANGER
SHOCK HAZARD Capacitor discharge tools that are not designed and labeled for
biphasic use are inadequate for use on biphasic defibrillators and will take several
minutes to discharge the energy capacitor.
