Abstract

An external defibrillator system, the system comprising: one or more sensors configured to detect one or more parameters associated with performance of CPR; one or more wearable computing devices configured to provide feedback to a user about CPR performed by the user based on the one or more parameters associated with the performed CPR; and an external defibrillator comprising: a memory configured to store instructions; and a processor to execute the instructions to perform an operation comprising: analyzing the one or more parameters to determine a CPR performance metric indicative of an overall performance of the user.

First claim

What is claimed is:

1 . An external defibrillator system, the system comprising:
one or more sensors configured to detect one or more parameters associated with performance of CPR; one or more wearable computing devices configured to provide feedback to a user about CPR performed by the user based on the one or more parameters associated with the performed CPR; and an external defibrillator comprising:
a memory configured to store instructions; and
a processor to execute the instructions to perform an operation comprising:
analyzing the one or more parameters to determine a CPR performance metric indicative of an overall performance of the user.

2 . The system of claim 1 , wherein the one or more wearable computing devices include at least one of the following: a tablet computing device, a headset, wearable glasses, and a smartphone.

3 . The system of claim 1 , wherein at least one of the one or more wearable computing devices directs feedback to one predetermined user.

4 . The system of claim 1 , wherein the one or more wearable computing devices includes one or more of a watch or wearable glasses.

5 . The system of claim 4 , wherein the wearable computing device includes wearable glasses having one or more lenses.

6 . The system of claim 5 , wherein the visual summary is displayed on at least one lens of the wearable glasses.

7 . The system of claim 1 , wherein generating the CPR performance metric includes generating data reflecting measurements of two or more actions performed on the victim.

8 . The system of claim 1 , wherein the CPR performance metric is based, at least in part, on weighted values applied to the one or more parameters.

9 . The system of claim 8 , wherein the weighted values are applied to at least one of the following: rate of chest compressions, depth of chest compressions, and fraction based on a guideline.

10 . The system of claim 1 , wherein the wearable computing device is configured to provide a visual summary including the CPR performance metric within five minutes of cessation of the CPR by the rescuer.

11 . The system of claim 1 , wherein the CPR performance metric is based on a function that weights each of the parameters according to weights determined using a neural network.

12 . The system of claim 1 , wherein the CPR performance metric is based on a function that weights each of the parameters according to weights determined using a linear regression technique.

13 . The system of claim 1 , wherein the wearable computing device is configured to receive input data from the user.

14 . The system of claim 1 , comprising a heads-up device to provide feedback to a user about CPR performed by the user based on the one or more parameters associated with the performed CPR.

15 . An external defibrillator system, the system comprising:
one or more sensors configured to detect one or more parameters associated with performance of CPR; a heads-up device configured to provide feedback to a user about CPR performed by the user based on the one or more parameters associated with the performed CPR; and an external defibrillator comprising:
a memory configured to store instructions; and
a processor to execute the instructions to perform an operation comprising:
analyzing the one or more parameters to determine a CPR performance metric indicative of an overall performance of the user.

16 . The external defibrillator system of claim 15 , wherein the CPR performance metric is based, at least in part, on weighted values applied to the one or more parameters.

17 . A computer-implemented method for providing summary information for CPR performance, the method comprising:
sensing one or more parameters associated with performance of CPR performed on a victim by a rescuer; identifying a timing interval over which performance is to be analyzed and gathering data from the sensing of the one or more parameters during the time interval; generating, from analysis of the parameters, a CPR performance metric that condenses data sensed for the one or more parameters into a single metric indicative of overall performance of the CPR over the identified interval; and providing, for display on a wearable computing device, a visual summary including the CPR performance metric within five minutes of cessation of the CPR by the rescuer.

18 . The method of claim 17 , wherein the wearable computing device includes one or more of a watch or wearable glasses.

19 . The method of claim 18 , wherein the wearable computing device includes wearable glasses having one or more lenses.

20 . The method of claim 19 , wherein the visual summary is displayed on at least one lens of the wearable glasses.

21 . The method of claim 17 , wherein generating the CPR performance metric comprises calculating the CPR performance metric (CPM) according to CPM=f(w rate *X rate ,w Depth *X depth ,w fraction *X fraction ) where w rate , w depth , and w fraction comprise weighting factors for each of rate of chest compressions, depth of chest compressions and fraction and X rate , X depth , and X fraction are calculated metrics for rate of chest compressions, depth of chest compressions, and fraction based on a guideline.

22 . The method of claim 17 , wherein generating the CPR performance metric comprises calculating the CPR performance metric based on a function that weights each of the parameters according to weights determined using a neural network.

23 . The method of claim 17 , wherein generating the CPR performance metric comprises calculating the CPR performance metric based on a function that weights each of the parameters according to weights determined using a linear regression technique.

24 . The method of claim 17 , wherein providing the visual summary comprises providing a graphical display of CPR compression rate, CPR compression depth and CPR fraction during the identified interval.

25 . The method of claim 17 , wherein providing the visual summary comprises providing per-parameter metrics with each per-parameter metric condensing data for the parameter to provide a single metric indicative of the CPR quality for that parameter.

26 . The method of claim 17 , wherein providing, for display to a user, a visual summary including the CPR performance metric comprises providing the visual summary within one minute of cessation of the CPR by the rescuer.

27 . The method of claim 17 , wherein the sensors comprise at least one of chest compression sensors, patient ventilation sensors, and electrocardiogram sensors.

28 . The method of claim 17 , wherein providing the visual summary for display comprises wirelessly transmitting data about the one or more activities from a device that senses the one or more activities to a remote device having a visual display device display.

29 . The method of claim 17 , wherein the CPR performance metric comprises a score that indicates, by one alpha-numeric indicator, a quality level with which one or more CPR related activities were performed.

30 . The method of claim 17 , comprising monitoring electrocardiogram data of the victim while the one or more activities are occurring, and providing with a defibrillator at least one of charging the defibrillator and shocking the victim without manual intervention of a rescuer.
