Getting Ready
CPSS during CPR
The CPSS DURING CPR option determines whether or not Continuous Patient Surveillance System
(CPSS) is active during CPR Time. The factory default setting is
OFF.
If the
CPSS DURING CPR option is ON, the AED “watches” for potentially shockable ECG rhythms (e.g.,
refibrillation) throughout CPR Time. When CPSS detects a potentially shockable ECG rhythm, the AED
prompts
PUSH ANALYZE, and CPR is temporarily interrupted while the user stays clear of the patient
during the analysis. With CPSS on during CPR Time, CPR artifact may or may not be interpreted as a
shockable ECG rhythm. However, when CPSS is off during CPR, the presence of a shockable ECG
rhythm will not be detected until CPR Time is over or the next analysis.
The determination of whether or not the
CPSS DURING CPR option is selected to be turned ON may be
based on the following:
• Post shock CPR protocol
• Effects of interrupting CPR
• Skill and training level of the care providers
If CPSS is turned on during CPR Time, protocols should be developed to manage the possible
repeated false positives of CPSS alerts during CPR. The ability of the personnel in the service to follow
such a protocol should be taken into account. For more information, refer to Appendix A.
Motion Detection
The MOTION DETECTION option determines whether or not the motion detection system is active during
analysis. The factory default setting is
ON.
When this option is
OFF, analysis of the ECG is allowed to proceed uninhibited by the presence of
motion, which may or may not cause artifact on the ECG. Artifact on the ECG may lead to erroneous
ECG interpretations. However, when this option is on, motion that is detected may temporarily inhibit
analysis from proceeding, for example in patients with agonal breathing.
The determination of whether or not the
MOTION DETECTION OPTION is selected to be turned off includes
the consideration of:
• Skill and training level of the care providers
• Frequency of the occurrence of agonal breathing
• Other motion artifact during use of the AED
For more information, refer to Appendix A.
Asystole Detector
This option enables the ASYSTOLE DETECTOR. When active, the ASYSTOLE DETECTOR notifies the user
that asystole has been detected for a number of consecutive analyses over a period of time. The time
interval determines how long asystole must be detected before the
ASYSTOLE message appears. The
time intervals that can be selected are: 4 to 60 minutes (in one-minute intervals). The factory default
setting is
OFF.
Audio Recording
AUDIO RECORDING is only displayed if the option is installed. The AUDIO RECORDING option may be ON or
OFF. If it is ON, the AED records the audio during patient care. If it is OFF, the AED does not record the
audio. The factory default setting is
ON.
Paper Size
The PAPER SIZE option defines the size of the paper for the printer used to print out AED data. The
choices are 8 1/2 x 11 inches and A4. The factory default is 8 1/2 x 11 inches.
