Abstract

An example of a CPR data recording system includes a hand-held chest compression measurement device and an external computing device communicatively coupled to the hand-held chest compression measurement device. The hand-held chest compression measurement device includes a housing, a motion sensor, a communication device, a memory disposed within the housing, and a processor disposed within the housing. The processor is configured to process a signal output from the motion sensor, calculate chest compression data from the processed signal output, evaluate the chest compression data after a delay from a start of the chest compressions to identify chest compressions that satisfy a pre-determined quality criterion, record the chest compression data in the memory, and send the recorded chest compression data to the external computing device via the communication device. The external computing device is configured to enable a review of the chest compression data.

First claim

What is claimed is:

1. A CPR data recording system comprising:
a hand-held chest compression measurement device;
an external computing device communicatively coupled to the hand-held chest compression measurement device; and
a blood pressure cuff configured for wireless communication with the hand-held chest compression measurement device,
the hand-held chest compression measurement device comprising:
a housing;
a motion sensor;
a communication device;
a memory disposed within the housing; and
a processor disposed within the housing and configured to:
process a signal output from the motion sensor,
calculate chest compression data from the processed signal output,
evaluate the chest compression data after a delay from a start of chest compressions to identify chest compressions that satisfy a pre-determined quality criterion,
record the chest compression data in the memory, and
send the recorded chest compression data to the external computing device via the communication device,

wherein the external computing device is configured to enable a review of the chest compression data,
the communication device is configured to receive blood pressure measurements from the blood pressure cuff, and
the processor is configured to store the blood pressure measurements in the memory.

2. The CPR data recording system of claim 1 ,
wherein the chest compression data comprises chest displacement data, and
wherein the pre-determined quality criterion comprises a minimum displacement.

3. The CPR data recording system of claim 1 ,
wherein the chest compression data comprises chest displacement data, and
wherein the pre-determined quality criterion comprises a maximum displacement.

4. The CPR data recording system of claim 1 , wherein the processor is configured to generate rescuer feedback based on the evaluation of the chest compression data after the delay.

5. The CPR data recording system of claim 4 , comprising an output device configured to provide the rescuer feedback comprising a message indicating good compressions during the chest compressions that satisfy the pre-determined quality criterion.

6. The CPR data recording system of claim 4 , comprising an output device configured to provide the rescuer feedback comprising a message to push harder during chest compressions that fail to satisfy the pre-determined quality criterion.

7. The CPR data recording system of claim 1 , wherein the processor is configured to calculate a percentage of chest compressions that meet the pre-determined quality criterion.

8. The CPR data recording system of claim 1 , wherein the communication device is configured to communicate with the external computing device via wireless short-range communications.

9. The CPR data recording system of claim 8 , wherein the wireless short-range communications comprise Bluetooth® protocol communications.

10. The CPR data recording system of claim 1 , wherein the external computing device comprises a handheld computing device.

11. The CPR data recording system of claim 10 , wherein the external computing device comprises a cell phone.

12. The CPR data recording system of claim 1 , wherein the hand-held chest compression measurement device is configured for use without connection to a defibrillator.

13. The CPR data recording system of claim 1 , wherein the hand-held chest compression measurement device comprises a switch configured to enable a selection between an adult mode and a pediatric mode.

14. The CPR data recording system of claim 1 , wherein the processor is configured to initiate a communication to emergency medical services in conjunction when the processor initiates processing of the signal output from the motion sensor.

15. The CPR data recording system of claim 1 , wherein the processor is configured to send the recorded chest compression data after a CPR administration.

16. The CPR data recording system of claim 15 , wherein the review of the chest compression data comprises a review after the CPR administration.

17. The CPR data recording system of claim 1 , wherein the review of the chest compression data comprises playback of the chest compression data.

18. A CPR data recording system comprising:
a hand-held chest compression measurement device; and
an external computing device communicatively coupled to the hand-held chest compression measurement device,
the hand-held chest compression measurement device comprising:
a housing;
a motion sensor;
a communication device;
a memory disposed within the housing;
a processor disposed within the housing and configured to:
process a signal output from the motion sensor,
calculate chest compression data from the processed signal output,
evaluate the chest compression data after a delay from a start of chest compressions to identify chest compressions that satisfy a pre-determined quality criterion,
record the chest compression data in the memory, and
send the recorded chest compression data to the external computing device via the communication device; and

a switch configured to enable a selection between an adult mode and a pediatric mode,

wherein the external computing device is configured to enable a review of the chest compression data.

19. The CPR data recording system of claim 18 ,
wherein the chest compression data comprises chest displacement data, and
wherein the pre-determined quality criterion comprises a minimum displacement.

20. The CPR data recording system of claim 18 ,
wherein the chest compression data comprises chest displacement data, and
wherein the pre-determined quality criterion comprises a maximum displacement.

21. The CPR data recording system of claim 18 , wherein the processor is configured to generate rescuer feedback based on the evaluation of the chest compression data after the delay.

22. The CPR data recording system of claim 21 , comprising an output device configured to provide the rescuer feedback comprising a message indicating good compressions during the chest compressions that satisfy the pre-determined quality criterion.

23. The CPR data recording system of claim 21 , comprising an output device configured to provide the rescuer feedback comprising a message to push harder during chest compressions that fail to satisfy the pre-determined quality criterion.

24. The CPR data recording system of claim 18 , wherein the processor is configured to calculate a percentage of chest compressions that meet the pre-determined quality criterion.

25. The CPR data recording system of claim 18 , wherein the communication device is configured to communicate with the external computing device via wireless short-range communications.
