Patient Analysis System
The DDU-2000 Series Patient Analysis System ensures that the pad/patient impedance is within the proper range
and analyzes the patient’s ECG rhythm to determine whether a shock is required. On detection of a non-shockable
rhythm, the user is prompted to perform CPR. For shockable rhythms, the AED automatically charges in preparation
for shock delivery.
The patient analysis system will detect electrical “noise” or artifact in the ECG signal that may interfere with accurate
rhythm analysis. This artifact may be caused by excessive motion to the patient or by external electrical noise. When
this artifact is present, the AED will prompt the user to “Stop motion” or “Stop Interference” until the ECG signal is
free of noise and then proceed to analysis.
