Determine if the person needs rescue breathing or external cardiac compressions; then take
appropriate action.
Preventing Electrostatic Discharge Damage
Electrostatic discharge (ESD) can damage equipment and impair electrical circuitry. ESD occurs when
electronic components are improperly handled; it can result in complete or intermittent failures.
