Abstract

A method of providing assistance to a rescuer to perform cardiopulmonary resuscitation (CPR) is disclosed. The method includes receiving sensor data from one or more sensors regarding CPR compressions. The method also includes determining, on a real-time basis, a CPR parameter value for each CPR compression. The method also includes determining a summarized CPR parameter value based on each CPR parameter value. The method also includes determining whether summarized CPR parameter value satisfies a CPR threshold value. In response to determining whether the summarized CPR parameter value satisfies the CPR threshold value, the method includes causing a user interface to provide feedback information for assisting the rescuer to perform CPR on a patient.

First claim

What is claimed is:

1 . A portable medical device for providing assistance to a rescuer performing cardiopulmonary resuscitation (CPR), the portable medical device comprising:
a user interface configured to provide information to the rescuer; one or more sensors configured to be placed in physical contact with a patient; and a processor configured to:
receive sensor data from the one or more sensors regarding CPR compressions;
determine, on a real-time basis, a CPR parameter value for each CPR compression, wherein the CPR parameter value represents a chest compression depth, a chest compression rate, or a chest recoil;
determine an average CPR parameter value based on the CPR parameter value for each CPR compression;
determine whether the average CPR parameter value satisfies a CPR threshold value; and
in response to determining whether the average CPR parameter value satisfies the CPR threshold value, cause the user interface to provide feedback information for assisting the rescuer to perform CPR on the patient.

2 . The portable medical device of claim 1 , wherein the average CPR parameter value is a weighted average of the CPR parameter values.

3 . The portable medical device of claim 1 , wherein the processor is further configured to determine whether a predetermined percentage of CPR parameter values have fallen below a minimum CPR threshold value or exceeded a maximum CPR threshold value.

4 . The portable medical device of claim 1 , wherein the feedback information includes a visual output, an audio output, a tactile output, or a combination thereof.

5 . The portable medical device of claim 1 , wherein the CPR parameter value represents chest compression depth, and wherein the feedback information indicates whether an average chest compression depth is adequate, too shallow, too deep, within predetermined guidelines or limits, or outside predetermined guidelines or limits.

6 . The portable medical device of claim 1 , wherein the CPR parameter value represents the chest compression rate, and wherein the feedback information indicates whether an average chest compression rate is too fast, too slow, within predetermined guidelines or limits, or outside predetermined guidelines or limits.

7 . The portable medical device of claim 1 , wherein the CPR parameter value represents the chest recoil, and wherein the feedback information indicates whether an average chest recoil is adequate, inadequate, within predetermined guidelines or limits, or outside predetermined guidelines or limits.

8 . A portable medical device for providing assistance to a rescuer performing cardiopulmonary resuscitation (CPR), the portable medical device comprising:
a user interface configured to provide information to the rescuer; one or more sensors configured to be placed in physical contact with a patient; and a processor configured to:
receive sensor data from the one or more sensors regarding CPR compressions;
determine, on a real-time basis, a CPR parameter value for each CPR compression;
determine a summarized CPR parameter value based on each CPR parameter value;
determine whether the summarized CPR parameter value satisfies a CPR threshold value; and
in response to determining whether the summarized CPR parameter value satisfies the CPR threshold value, cause the user interface to provide feedback information for assisting the rescuer to perform CPR on the patient.

9 . The portable medical device of claim 8 , wherein the CPR parameter value represents a chest compression depth, a chest compression rate, or a chest recoil.

10 . The portable medical device of claim 8 , wherein the summarized CPR parameter value represents an average chest compression depth for the CPR compressions, an average chest compression rate for the CPR compressions, or an average chest recoil for the CPR compressions.

11 . The portable medical device of claim 8 , wherein the summarized CPR parameter value represents a weighted chest compression depth average for the CPR compressions, a weighted chest compression rate average for the CPR compressions, or a weighted chest recoil average for the CPR compressions.

12 . The portable medical device of claim 8 , wherein the summarized CPR parameter value indicates whether a predetermined percentage of at least one CPR parameter value has fallen below a minimum threshold or exceeded a maximum threshold.

13 . The portable medical device of claim 8 , wherein the feedback information includes a visual output, an audio output, a tactile output, or a combination thereof.

14 . The portable medical device of claim 8 , wherein the feedback information indicates whether an average chest compression depth is adequate, too shallow, too deep, within predetermined guidelines or limits, or outside predetermined guidelines or limits.

15 . The portable medical device of claim 8 , wherein the feedback information indicates whether an average chest compression rate is too fast, too slow, within predetermined guidelines or limits, or outside predetermined guidelines or limits.

16 . The portable medical device of claim 8 , wherein the feedback information indicates whether an average chest recoil is adequate, inadequate, within predetermined guidelines or limits, or outside predetermined guidelines or limits.

17 . The portable medical device of claim 1 , wherein the feedback information provides an indication to change a rate of chest compressions or a depth of chest compressions.

18 . The portable medical device of claim 1 , wherein the user interface, the one or more sensors, and the processor are integrated into a defibrillator or a patient monitoring device.

19 . A method of providing assistance to a rescuer performing cardiopulmonary resuscitation (CPR), the method comprising:
receiving sensor data from the one or more sensors regarding CPR compressions; determining, on a real-time basis, a CPR parameter value for each CPR compression; determining a summarized CPR parameter value based on each CPR parameter value; determining whether the summarized CPR parameter value satisfies a CPR threshold value; and in response to determining whether the summarized CPR parameter value satisfies the CPR threshold value, causing a user interface to provide feedback information for assisting the rescuer to perform CPR on a patient.

20 . The method of claim 19 , wherein the CPR parameter value represents a chest compression depth, a chest compression rate, or a chest recoil.
