Defibrillator synchronization tester.

Area of Science:

• Biomedical Engineering
• Cardiovascular Technology

Background:

• Defibrillator sync output provides ECG signals for synchronized cardioversion, crucial for treating cardiac arrhythmias.
• Accurate R-wave timing during cardioversion prevents inducing ventricular fibrillation.
• GE patient monitors offer analog output for ECG or blood pressure, enabling synchronized balloon pumps for cardiac assist.

Purpose of the Study:

• To describe the process and importance of checking defibrillator sync output signals.
• To highlight the role of these signals in synchronized cardioversion and cardiac assist.
• To introduce a method for verifying defibrillator sync signal functionality.

Main Methods:

• Utilizing a GE defibrillator sync tester for signal verification.
• Implementing a loop-back path for signals to display on the patient monitor.
• Performing checks during planned maintenance and after significant component replacements.

Main Results:

• The defibrillator sync tester allows for direct display of sync signals on the patient monitor.
• This eliminates the need for external oscilloscopes, simplifying the checkout process.
• Ensures proper functioning of the defibrillator sync and analog output features.

Conclusions:

• Regular checks of defibrillator sync signals are essential for safe and effective synchronized cardioversion.
• The GE defibrillator sync tester provides an efficient and integrated solution for signal verification.
