Abstract

A chest compression monitor for measuring the depth of chest compressions achieved during CPR. A displacement detector produces a displacement signal indicative of the displacement of the CPR recipient's chest toward the recipient's spine. A signaling mechanism provides chest compression indication signals prompting a CPR provider to provide a chest compression force at a desired depth and rate. The device is held to the dorsal surface of the hand during use and provides a display for feedback, which is readily visible to the CPR provider.

First claim

What is claimed is:

1. A first compression monitor configured to be associated with a plurality of compression monitors, the first compression monitor being adapted to be associated with a member of a rapid response team (RRT) in a hospital environment, wherein the first compression monitor and each of the plurality of compression monitors are configured to be carried by a different RRT member, the first compression monitor comprising:
a device configured to:
generate signals indicative of chest compressions,
determine chest compression data based on the signals indicative of the chest compressions,
store the chest compression data, and
transmit compression information from the first compression monitor to be received by a different compression monitor of the plurality of compression monitors as a notification that CPR is in progress, wherein the compression information is based on the chest compression data;

a housing configured as a holder for the device; and
a strap connected to the housing and adapted to secure the housing to a hand of the member of the RRT.

2. The first compression monitor of claim 1 wherein the first compression monitor is configured to coordinate communications amongst the plurality of compression monitors adapted to be associated with the RRT.

3. The first compression monitor of claim 1 wherein the device is configured to store the chest compression data comprising historical chest compression parameters.

4. The first compression monitor of claim 3 wherein the determined chest compression data comprises current chest compression parameters and further wherein the device is configured to compare the historical chest compression parameters with current chest compression parameters and determine CPR effectiveness information.

5. The first compression monitor of claim 3 wherein the device is configured to transmit the historical chest compression parameters to a central control system adapted to be associated with the plurality of compression monitors.

6. The first compression monitor of claim 1 wherein the device is configured to receive texts, preprogrammed responses, and audio responses from the plurality of compression monitors.

7. The first compression monitor of claim 1 wherein the device is configured to send, from the first compression monitor to the different compression monitor, at least one of hospital information, RRT member identification information, RRT member location information, CPR guideline information, and patient information.

8. The first compression monitor of claim 7 wherein the hospital information includes a hospital code and a response to the hospital code.

9. The first compression monitor of claim 1 wherein the device further stores historical chest compression parameters.

10. The first compression monitor of claim 1 wherein the device supports at least one of universal serial bus (USB) communication and wireless communication.

11. The first compression monitor of claim 1 further wherein the housing comprises a strap configured to secure the first compression monitor to the dorsal surface of the hand of the member of the RRT at least while the member of the RRT is manually compressing the chest of a patient.

12. The first compression monitor of claim 1 wherein the device comprises one or more accelerometers.

13. The first compression monitor of claim 12 wherein the chest compression data comprises an acceleration of the chest of a patient, a depth of chest compression, an average depth of chest compression, a rate of chest compression, a timing of ventilation pauses, a start and end of each compression, a zero-point of acceleration, a velocity, and a change in a direction of the velocity.

14. The first compression monitor of claim 1 wherein the device is configured to communicate according to authentication protocols.

15. The first compression monitor of claim 1 wherein the device is compatible with one or more of proximity sensors and identification sensors in the hospital environment.

16. The first compression monitor of claim 1 , wherein the first compression monitor is remote from the different compression monitor of the plurality of compression monitors.

17. The first compression monitor of claim 1 , wherein the first compression monitor and each of the plurality of chest compression monitors are each configured to transmit and receive notifications that CPR is in progress.

18. The first compression monitor of claim 1 , wherein the first compression monitor is adapted to communicate with compression monitors of the plurality of compression monitors.

19. The first compression monitor of claim 1 , wherein the strap comprises an elastic band configured to be wrapped around the hand of the member of the RRT.

20. A hospital system for use by a rapid response team (RRT) in a hospital environment, the hospital system comprising:
a plurality of devices wherein at least one of the plurality of devices is configured to coordinate communications amongst the plurality of devices, the plurality of devices including at least one compression monitor,
and further wherein the at least one compression monitor comprises:

a device configured to:
generate signals indicative of chest compressions,
determine chest compression data based on the signals indicative of chest compressions,
store the chest compression data, and
transmit compression information from the at least one compression monitor to one or more other of the plurality of devices as a notification that CPR is in progress, wherein the compression information comprises the chest compression data;
a housing configured as a holder for the device; and
a strap connected to the housing and adapted to secure the housing to a hand of a member of the RRT.
