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. |
|
|
|
|
protocol | 0.5, 1.0, 1.5, 2.0, | 1.0 | Sets the time interval used to determine if a delivered |
timeout | 2.5, 3.0, 3.5, |
| shock should be counted as part of the current Shock |
(minutes) | ∞ (infinite) |
| Series. |
|
|
|
|
CPR timer | 0.5, 1.0, 1.5, | 1.0 | Sets the length of the CPR pause period* that |
(minutes) | 2.0, 2.5, 3.0 |
| 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.
