Abstract

Increasing blood circulation, lowering intracranial pressure, and increasing cerebral perfusion pressure during the administration of cardiopulmonary resuscitation by gravity-assist due to elevation of one or both of the torso and head of an individual.

Claims (52)

1. An elevation device, comprising:

a base that is configured to be positioned atop a support surface;

a support member that is configured to elevate an individual's thorax and head at an angle relative to the individual's legs such that the thorax is elevated relative to the individual's legs by between about 5 and 15 cm relative and the head is elevated relative to the individual's legs by between about 8 and 25 cm; and

one or more defibrillation electrodes that are configured to deliver at least one shock to the individual's heart while the individual's thorax and head are elevated, wherein the one or more defibrillation electrodes are coupled with one or both of the base and the support member.

2. The elevation device of claim 1 , wherein:

each of the at least one shock comprises about 100-400 joules.

3. The elevation device of claim 1 , further comprising:

at least one user interface that enables a user to trigger delivery of the at least one shock or to set one or both of a position and an angle of a chest compression device.

4. The elevation device of claim 3 , wherein:

the at least one user interface comprises:

a first user interface that enables a user to trigger delivery of the at least one shock; and

a second user interface that enables the user to set one or both of a position and an angle of a chest compression device relative to the support member.

5. The elevation device of claim 1 , further comprising:

a battery that provides power to deliver the at least one shock.

6. The elevation device of claim 1 , further comprising:

a chest compression device coupleable with the support member.

7. The elevation device of claim 6 , wherein:

the chest compression device is configured to actively decompress the individual's chest in between chest compressions.

8. An elevation device, comprising:

a base that is configured to be positioned atop a support surface;

a support member that is configured to elevate an individual's thorax and head relative to the base such that the thorax is elevated relative to the support surface by between about 5 and 15 cm relative and the head is elevated relative to the support surface by between about 8 and 25 cm; and

a defibrillation device comprising one or more defibrillation electrodes that are configured to deliver at least one shock to the individual's heart while the individual's thorax and head are elevated in response to a result of an analysis of a condition of the individual, wherein the one or more defibrillation electrodes are coupled with one or both of the base and the support member.

9. The elevation device of claim 8 , wherein:

the analysis of the condition of the individual comprises examining an electrical output of the individual's heart to determine whether the individual is in a shockable rhythm; and

the result of the analysis is that the individual is in the shockable rhythm.

10. The elevation device of claim 8 , wherein:

software of the defibrillation device is configured to analyze the individual and cause one or both of CPR to be performed and a shock to be delivered.

11. The elevation device of claim 8 , wherein:

software of the defibrillation device is configured to automatically adjust one or more shock parameters selected from the group consisting of a strength of a shock, a duration of the shock, and a sequence of one or more shocks based on a sensed heart rhythm of the individual.

12. The elevation device of claim 8 , wherein:

the defibrillation device is configured to provide audio feedback, video feedback, or both audio and video feedback to a rescuer regarding a quality of chest compressions being administered.

13. The elevation device of claim 8 , further comprising:

an intrathoracic pressure regulation device.

14. A method for resuscitating an individual, comprising:

elevating an individual's thorax and head relative to a support surface such that the thorax is elevated above the support surface by between about 5 and 15 cm and the head is elevated above the support surface by between about 8 and 25 cm;

performing chest compressions on the individual while the thorax and head are elevated;

analyzing a condition of the individual; and

in response to the analysis of the condition, delivering at least one shock to the individual's heart using one or more defibrillation electrodes of a defibrillation device after performing chest compressions for a period of at least one minute and while the thorax and head are elevated.

15. The method for resuscitating an individual of claim 14 , wherein:

the at least one shock is triggered manually by a rescuer.

16. The method for resuscitating an individual of claim 14 , wherein:

the analysis of the condition is performed by software of the defibrillation device; and

the at least one shock is triggered automatically by the defibrillation device.

17. The method for resuscitating an individual of claim 14 , further comprising:

sensing a heart rhythm of the individual; and

adjusting one or more shock parameters selected from the group consisting of a strength of a shock, a duration of the shock, and a sequence of one or more shocks based on the sensed heart rhythm of the individual.

18. The method for resuscitating an individual of claim 14 , wherein:

delivering at least one shock comprises delivering sequential biphasic shocks of between 120-200 joules.

19. The method for resuscitating an individual of claim 18 , wherein:

alternating shocks of the sequential biphasic shocks move in an opposite polarity between the one or more defibrillation electrodes.

20. The method for resuscitating an individual of claim 14 , further comprising:

providing, by the defibrillation device, audio feedback, video feedback, or both audio and video feedback to a rescuer regarding a quality of chest compressions being administered.
