Press the ANALYZE button to begin the analysis of the patient’s ECG rhythm and to determine
if a shockable rhythm is present.
An ANALYZING ECG message is displayed for 6 to 12 seconds while the patient’s ECG is
analyzed. Once the analysis is completed, the unit indicates whether or not a shock is advised.
The analysis normally consists of three consecutive 3-second ECG rhythm analyses. If at least
two of the three analyses determine that the patient has a shockable rhythm, the unit
automatically charges to the preconfigured energy level and prompts the operator to shock the
patient. If two or more of the three 3-second ECG analyses do not detect a shockable rhythm,
the unit alerts the operator that no shock is advised.
WARNING! ECG rhythm analysis does not warn of patient asystole, which is not a shockable
rhythm.
When a nonshockable rhythm is detected, the unit displays a NO SHOCK ADV. message.
Follow the local protocols to continue CPR or other life support, and re-analyze the ECG at
appropriate intervals.
Note: When a nonshockable rhythm is detected, the R Series does not prevent the user from
manually defibrillating the patient.
When a shockable rhythm is detected (ventricular fibrillation or wide-complex tachycardia
with heart rate > 150), one of the following occur:
• Units with the automatic charge option enabled automatically charge to the preconfigured or
user selected energy setting.
