Abstract

Systems and methods for applying enhanced 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 by an operator, comprising:

a compression element that is pressed and lifted by the operator;

a flexible surface element operably coupled with the compression element by a connection mechanism and configured to contact the individual'"'"'s chest, the flexible surface element removably attachable to a chest area of the individual, the flexible surface element configured to decouple from the compression element when a decompression force exceeds a predetermined limit;

an operator interface that provides guidance to the operator as to how to perform chest compressions;

a processor operably coupled with the operator interface; and

a memory that is configured to store instructions executable by the processor to;

provide a set of operator instructions to perform a first conditioning protocol for increasing circulation in the individual by compressing the chest in a repeated manner for a certain number of chest compressions, a second conditioning protocol for pausing or reducing circulation in the individual following the first conditioning protocol by stopping chest compressions for a certain time duration, and a third conditioning protocol for increasing circulation in the individual following the second protocol by again compressing the chest in a repeated manner for a certain number of chest compressions.

2. The system according to claim 1, wherein each of the first and third conditioning protocols comprise a series of periodic active chest compressions and decompressions.

3. The system according to claim 1, wherein each of the first and third conditioning protocol comprise a duration, and the first conditioning protocol duration is different from the second conditioning protocol duration.

4. The system according to claim 1, wherein each of the first and third conditioning protocol comprise a duration, and the first conditioning protocol duration is equal to the second conditioning protocol duration.

5. The system according to claim 1, wherein the first conditioning protocol comprises a duration of about 40 seconds, the duration of the second conditioning protocol is about 20 seconds, and the third conditioning protocol comprises a duration of about 40 seconds.

6. The system according to claim 1, wherein the operator interface comprises a display subsystem that provides at least a portion of the guided treatment instructions.

7. The system according to claim 1, wherein the operator interface comprises an audio output device that provides at least a portion of the guided treatment instructions.

8. The system according to claim 7, wherein the audio output device comprises a loudspeaker.

9. The system according to claim 1, wherein the operator interface comprises a display subsystem and an audio output device that provide at least a portion of the guided treatment instructions.

10. The system according to claim 1, further comprising a means for delivering an electrical defibrillation treatment to the individual.

11. The system according to claim 1, wherein the set of operator instructions is based at least in part on a physiological parameter of the patient, and wherein the physiological parameter of the patient is selected from the group consisting of a ventilation rate, a body temperature, a heart rate, a respiratory rate, a vital sign, and an end tidal carbon dioxide measure.

12. The system according to claim 1, further comprising a pressure regulator mechanism that modulates pressure within an airway of the individual.

13. The system according to claim 1, wherein the memory is configured to store instructions executable by the processor to receive information indicating whether the operator is following the set of operator instructions and to provide a signal indicating whether the operator is following the set of operator instructions.

14. The system according to claim 1, wherein the flexible surface element coupled with the compression element and removably attachable to the chest area of the individual is from 2 to 4 times larger than a compressive area defined by a portion of the compression element that couples to the flexible surface element.

15. The system according to claim 1, wherein the flexible surface element coupled with the compression element and removably attachable to the chest area of the individual includes an adhesive for attaching to the chest area of the individual.

16. The system according to claim 1, wherein the connection mechanism comprises magnetic connection between the flexible surface element and the compression element.
