8.3 Defibrillation pulse
Form
• Biphasic pulsed defibrillation pulse with approximately constant phases for opti-
mal physiological compatibility.
• Maintains the energy delivered to the patient at an approximately constant level
with regard to patient resistance by applying pulse-pause modulation that varies
according to measured patient resistance.
Default energy settings
Accuracy at 50Ω: ± 3 J or ± 15 % (the higher value is assumed)
SCHILLER's customer service department can change the default energy levels to
the following values:
1 – 2 – 4 – 6 – 8 – 15 – 30 – 50 – 70 – 90 –110 – 130 – 150 J (adults)
1 – 2 – 4 – 6 – 8 – 15 – 30 – 50 – 70 J (children)
(automatic adaptation when paediatric pads are connected)
Cycle time: rhythm analysis –
shock availability (in semi-auto-
matic mode)
With full battery:
After 15 discharges with max.
energy:
(Maximum time between start of the analysis and shock availability, in semi-auto-
matic mode)
< 11 seconds
< 11 seconds
Cycle time: switch-on of the de-
vice – shock availability (in
semi-automatic mode)
