Abstract

Systems and methods for applying guided active compression decompression cardiopulmonary resuscitation are provided. Exemplary systems include a load cell, a handle, an adhesive pad. The handle and the adhesive pad are configured for magnetic coupling.

Claims

1. A system for applying guided active compression decompression cardiopulmonary resuscitation to an individual in need thereof, comprising:

a handle;

a measuring assembly in operative association with the handle; and

an adhesive pad,

wherein the handle and the adhesive pad are configured for releasable coupling,

wherein the handle is configured to decouple from the adhesive pad during a guided active compression decompression cardiopulmonary resuscitation procedure upon application of a decompressive force to the handle that exceeds a predetermined threshold, and

wherein the predetermined threshold comprises a release force that is less than a force required to separate the adhesive pad from a skin surface of the individual.

2. A system as in claim 1, wherein the measuring assembly comprises a force measuring device.

3. A system as in claim 1, wherein the measuring assembly comprises a distance measuring device.

4. A system as in claim 1, wherein the measuring assembly comprises a force and distance measuring device.

5. A system as in claim 4, wherein the force and distance measuring device comprises an accelerometer.

6. A system as in claim 1, wherein the handle and the adhesive pad are configured for magnetic coupling.

7. A system as in claim 1, wherein the handle and the adhesive pad are configured for releasable coupling via a mechanical interlock.

8. A system as in claim 7, wherein the mechanical interlock comprises a member selected from the group consisting of a ball and socket assembly, a cantilevered arm assembly, and a detent mechanism assembly.

9. A system as in claim 1, wherein the handle is coupled with a drive element of an automated reciprocating system.

10. A system as in claim 1, further comprising an intrathoracic pressure regulator (ITPR) system that modulates pressure within an airway of the individual.

11. A system as in claim 1, wherein the predetermined threshold is about 25 pounds.

12. A device for actively compressing and expanding an area of the body of an individual, the device comprising:

a compression element that is configured to be pressed and lifted, and

a flexible surface element operably coupled with the compression element and configured to be removably attached to a body part of the individual over a contact area;

wherein the compression element is configured to decouple from the surface element during a guided active compression decompression cardiopulmonary resuscitation procedure upon application of a decompressive force to the compression element that exceeds a predetermined threshold,

wherein the predetermined threshold comprises a release force that is less than a force required to separate the flexible surface element from the body part of the individual,

wherein the compression element is adapted to apply a compressive force to the body part through the surface element over a compressive area when the compression element is pressed, and

wherein the contact area is sized to be at least twice as large as the compressive area.

13. A device as in claim 12, wherein the surface element is a generally planar flexible contact pad having a lower surface, wherein the lower surface defines the contact area.

14. A device as in claim 13, wherein the lower surface of the contact pad includes an adhesive material.

15. A device as in claim 13, further comprising at least one measuring element associated with the contact pad, wherein the measuring element is configured to measure a physiological parameter of the patient.

16. A device as in claim 13, further comprising a display element associated with the contact pad.

17. A device as in claim 16, wherein the display element is configured to provide patient feedback information.

18. A device as in claim 12, further comprising at least one electrode associated with the surface element for applying electricity to the body part.

19. A device as in claim 12, further comprising at least one reference element associated with the surface element to aid in the proper placement of the surface element on the body part.

20. A device as in claim 12, wherein the predetermined threshold is about 25 pounds.

21. A system for providing a volume exchange cardiopulmonary resuscitation treatment to a patient, the system comprising:

a compression element that is configured to be pressed and lifted;

a flexible surface element operably coupled with the compression element and configured to be removably attached to a body part; and

an occlusion mechanism for occluding the patient'"'"'s airway during a decompression phase,

wherein the compression element is configured to decouple from the surface element during a volume exchange guided active compression decompression cardiopulmonary resuscitation procedure upon application of a decompressive force to the compression element that exceeds a predetermined threshold, and

wherein the predetermined threshold comprises a release force that is less than a force required to separate the flexible surface element from the body part of the patient.

22. A system as in claim 21, wherein the occlusion mechanism comprises a one-way valve.

23. A system as in claim 21, wherein the occlusion mechanism comprises a valve system that allows an operator to ventilate the patient.

24. A system as in claim 21, further comprising a vacuum source for actively removing respiratory gases from the patient'"'"'s lungs with a continuous or intermittent low-level vacuum.

25. A system as in claim 21, wherein the predetermined threshold is about 25 pounds.
