2  Safety and Care 
2 - 22  Instructions for Use 
Defibrillators 
  WARNING: The ECG function is designed to withstand the effects of defibrillation. However, 
when possible, disconnect the ECG leads during defibrillation since a malfunction of the safety 
controls could otherwise result in electrical burns for the patient. 
For patient safety, be sure to use defibrillators that do not have grounded patient circuits. 
Defibrillator Use and the ACUSON AcuNav Ultrasound Catheter 
  WARNING: The catheter is designed to withstand the effects of defibrillation. However, when 
possible, disconnect the connector from the ultrasound system during defibrillation because a 
malfunction of the safety controls could otherwise result in electrical burns for the patient. 
The catheter is designed to withstand the effects of defibrillation. There are no exposed 
conductive surfaces distal to the handle. Within the flexible shaft, a chassis ground shield 
covers all active circuits and conductors. 
Recovery Time After Defibrillation During a Catheter Procedure 
If you disconnect the SwiftLink catheter connector from the ultrasound system before 
defibrillation, the recovery time after defibrillation is equal to the time required to reconnect the 
connector to the ultrasound system. 
The recovery time after defibrillation for the ultrasound system: 
  Three (3) minutes if defibrillation is performed with the ultrasound system on. 
Implantable Devices 
  WARNING: Ultrasound systems, like other medical equipment, use high-frequency electrical 
signals that can interfere with implantable devices such as pacemakers and implantable 
cardioverter-defibrillators (ICDs). If the patient has such an implantable device, you should be 
aware of any interference in its operation and immediately power off the ultrasound system.
