Philips Medical Systems
Automatic protocol parameters
The HeartStart FR2+ is designed to follow an automatic protocol that guides
you through patient treatment with the defibrillator. The default settings for
programmable parameters used in the automatic protocol can be altered by
your Medical Director if desired.
The setup parameters in the following table are used to define the automatic
patient care protocol used by the FR2+. Many of these parameters interact
with each other, so it is very important to understand how each parameter
affects the protocol. The description of each parameter identifies any
interacting parameters in boldface type.
parameter settings default description
shock series 1, 2, 3, 4 3 Sets the number of shocks that must be delivered to
activate an automatic CPR pause.
The length of the CPR pause after completion of a Shock
Series is defined by the CPR Timer setting.
A new Shock Series begins when a shock is delivered:
• after the FR2+ is turned on
• after the automatic CPR pause, or
• after the Pause Key (if enabled) has been pressed, or
• if the time since the previous shock exceeds the
Protocol Timeout setting.

automatically starts when:
• a Shock Series is completed; or
• the Pause Key (if enabled) is pressed; or
• a No Shock Advised (NSA) decision is made, the NSA
CPR pause is enabled, and the conditions for using the
CPR Timer setting for the NSA CPR pause period are
met (see NSA Action).
After the CPR pause, the FR2+ returns to automatic
rhythm analysis.
* The CPR pause period is lengthened by 10 seconds to
allow time for initial voice prompting.
