Abstract

Methods and apparatus are provided for determining a defibrillation treatment protocol in an external defibrillator whereby a user may override a CPR-first default protocol. The method includes following steps configured in a defibrillator controller of issuing an inquiry; waiting for a response to the inquiry for a set time; ordering a CPR treatment protocol if no response is received within the set time; analyzing a response; ordering a CPR treatment protocol upon receiving a non-affirmative response to the inquiry; and ordering a shock treatment protocol upon receiving an affirmative response to the inquiry. Upon selecting a shock treatment protocol, the defibrillator performs a shock analysis under the shock treatment protocol, and either orders a CPR treatment protocol if shock treatment is not indicated by the shock analysis or provides a defibrillation shock if shock treatment is indicated by the shock analysis. Queries may be presented to a user in visual, audible, or both visual and audible format.

First claim

1 . A method for determining a defibrillation treatment protocol for an external defibrillator comprising:
issuing an inquiry with the external defibrillator; waiting for a response to the inquiry for a set time; ordering a CPR treatment protocol if no response is received within the set time; ordering a CPR treatment protocol if a non-affirmative response to the inquiry is received; and ordering a shock treatment protocol if an affirmative response to the inquiry is received.

2 . The method according to claim 1 , further comprising:
activating the external defibrillator; performing a shock analysis under the shock treatment protocol; ordering a CPR treatment protocol if shock treatment is not advised by the shock analysis; and providing a defibrillation shock if shock treatment is advised by the shock analysis.

3 . The method according to claim 2 , in which issuing the inquiry further comprises issuing the inquiry to a user of the external defibrillator. The method according to claim 2 , in which the external defibrillator includes a controller and issuing the inquiry comprises issuing the inquiry within the controller.

5 . The method according to claim 2 , in which the external defibrillator has CPR set as a default initial treatment protocol, and further comprising:
outputting a query to a user whether to bypass the default initial CPR protocol; initiating a timer upon outputting the query that runs for a set time from the outputting of the query; ordering the CPR protocol if a response has not been received within the set time from the outputting of the query; if a response to the query is received, analyzing the response; ordering the CPR protocol if the response to the query is negative; ordering the CPR protocol if the response to the query is any response other than affirmative; ordering a shock analysis if the response to the query is affirmative; providing a defibrillation shock if the shock analysis advises a shock be provided; and ordering the CPR treatment protocol if the shock analysis advises no shock be provided.

6 . The method according to claim 5 , further comprising receiving data from the patient into the external defibrillator via ECG probes which are attached to the patient and coupled to the external defibrillator.

7 . The method according to claim 6 , in which the data received from the patient into the external defibrillator comprises a response to the query.

8 . The method according to claim 5 , in which outputting the query further comprises outputting a series of queries.

9 . The method according to claim 5 , further comprising overriding, by immediately directing a shock therapy analysis, the:
outputting of the query to the user whether to bypass the default initial CPR protocol; initiating the timer upon outputting the query that runs for the set time from the outputting of the query; ordering the CPR protocol if a response has not been received within the set time from the outputting of the query; if the response to the query is received, analyzing the response; ordering the CPR protocol if the response to the query is negative; ordering the CPR protocol if the response to the query is any response other than affirmative; and ordering the shock analysis if the response to the query is affirmative.

10 . The method according to claim 1 further comprising bypassing, by immediately directing the shock therapy protocol, the:
issuing of the inquiry;
waiting for the response; and
ordering the CPR treatment protocol if no response is received within the set time.
