Abstract

A system comprising: a wrist-worn device configured to be worn on the wrist of a rescuer performing cardiopulmonary resuscitation (CPR), the wrist-worn device including: one or more sensors coupled with the wrist-worn device, the one or more sensors being configured to sense one or more parameters indicative of a fatigue level of the rescuer; and a sensor interface configured to provide the sensed parameters to one or more external computing devices via an interface; and a wearable computing device configured to be worn by a rescuer, the wearable computing device including: a device interface for receiving information related to CPR; and a display for displaying an indication of the received information.

First claim

What is claimed is:

1. A medical system for assisting a rescuer in providing care to a victim, the rescuer being one of multiple rescuers providing care to the victim, the medical system comprising:
a head mounted device, comprising a visual display, configured to be worn by the rescuer while providing CPR chest compressions on the victim or ventilation to the victim;
a wrist-worn device configured to be disposed on a wrist of the rescuer, the wrist-worn device including one or more sensors configured to sense data relating to an action being performed by the rescuer, wherein data displayed on the wrist-worn device changes based on a type of the action, wherein the data displayed changes based on whether or not the rescuer is currently administering CPR chest compressions; and
a patient monitor configured to wirelessly communicate with, and display feedback to the rescuer on, the head mounted device and the wrist-worn device, the patient monitor configured to:
receive, from the wrist-worn device, the sensed data, and
if the type of the action comprises the administering of CPR chest compressions, then determine, and display on the wrist-worn device chest compression feedback reflecting a depth and a rate of CPR chest compressions performed by the rescuer and, if the type of the action does not comprise the administering of CPR chest compressions, then change the data displayed on the wrist-worn device of the rescuer to display other information including patient data and/or ventilation feedback, and
if the type of the action comprises the administering of CPR chest compressions, then determine, and display on the head mounted device, information relating to performance of the rescuer in providing CPR chest compressions on the victim and information relating to performance of another rescuer of the multiple rescuers in simultaneously providing ventilation to the victim, and, if the type of the action comprises providing of ventilation to the victim, then determine, and display on the head mounted device, information relating to performance of the rescuer in the providing of ventilation to the victim and information relating to performance of another rescuer of the multiple rescuers in simultaneously providing CPR chest compressions on the victim.

2. The medical system of claim 1 , wherein the head mounted device includes wearable glasses.

3. The medical system of claim 2 , wherein feedback comprising at least a portion of the chest compression feedback is displayed on at least one lens of the wearable glasses.

4. The medical system of claim 1 , wherein the chest compression feedback reflects a CPR interval time.

5. The medical system of claim 4 , wherein the chest compression feedback further includes a perfusion performance indicator that fills over time to provide a real-time information directed to the depth and the rate of the chest compressions performed by the rescuer.

6. The medical system of claim 1 , wherein sensed data received from the patient monitor from the wrist-worn device includes sensed data regarding one or more physical parameters of the rescuer measured by the wrist-worn device during the resuscitation of the victim.

7. The medical system of claim 6 , wherein the patient monitor is configured to analyze the one or more physical parameters to determine whether a physical state of the rescuer has declined during the resuscitation of the victim.

8. The medical system of claim 7 , wherein the one or more physical parameters include at least one of heart rate, blood pressure, and inspired carbon dioxide (CO2) of the rescuer.

9. The medical system of claim 8 , wherein feedback displayed on the wrist-worn device includes at least one of an indication of whether the physical state of the rescuer is declining and the one or more physical parameters of the rescuer.

10. The medical system of claim 9 , wherein feedback displayed on the wrist-worn device includes an indication to switch activities based at least in part on whether the physical state of the rescuer has declined.

11. The medical system of claim 1 , wherein the one or more sensors comprise at least one chest compression sensor configured to sense motion associated with the chest compressions and to generate one or more signals indicative of chest motion.

12. The medical system of claim 11 , wherein the patient monitor is configured to:
receive, from the at least one chest compression sensor, the one or more signals indicative of chest motion, and
analyze the one or more signals indicative of chest motion to determine the rate and the depth of the chest compressions.

13. The medical system of claim 12 , wherein feedback displayed on the wrist-worn device comprises an indication of whether the rate and the depth of the chest compressions are within an acceptable range.

14. The medical system of claim 13 , wherein feedback displayed on the wrist-worn device comprises an indication to switch rescuers based at least in part on whether the rate and the depth are outside of the acceptable range.

15. The medical system of claim 1 , wherein the one or more sensors comprise one or more accelerometers that generate signals indicative of movement of the rescuer.

16. The medical system of claim 15 , wherein the one or more accelerometers are configured to sense motion associated with the chest compressions and to generate one or more signals indicative of chest motion.

17. The medical system of claim 16 , wherein the wrist-worn device is configured to:
analyze the one or more signals indicative of chest motion to determine the rate and the depth of the chest compressions.

18. The medical system of claim 17 , wherein the wrist-worn device is configured to provide feedback on the wrist-worn device comprising an indication of whether at least one of the rate and the depth of the chest compressions are within an acceptable range.

19. The medical system of claim 17 , wherein the wrist-worn device is configured to provide feedback on the wrist-worn device comprising an indication of whether chest release has been achieved.

20. The medical system of claim 1 , wherein the patient monitor is configured to display the chest compression feedback on the visual display of the head mounted device.

21. The medical system of claim 1 , wherein the patient monitor is configured to provide ventilation feedback to at least one of the multiple rescuers other than the rescuer who is administering the CPR chest compressions.

22. The medical system of claim 1 , wherein the data displayed on the wrist-worn device changes based on whether the rescuer is administering the CPR chest compressions or providing ventilation.

23. The medical system of claim 1 , wherein the data displayed on the wrist-worn device changes based at least in part on a task being performed by the rescuer, wherein the task comprises the administering of the CPR chest compressions or providing of ventilation.

24. The medical system of claim 21 , wherein the ventilation feedback associated with the providing of ventilation comprises ventilation prompts.

25. The medical system of claim 24 , wherein the one or more sensors configured to sense data relating to the action being performed by a rescuer comprise an airflow sensor.

26. The medical system of claim 25 , wherein the one or more sensors configured to sense data relating to the action being performed by a rescuer comprise the airflow sensor pr
