Elevation timing systems and methods for head up CPR
First Claim
1. A method for performing cardiopulmonary resuscitation (CPR), comprising:
- performing CPR by repeatedly compressing the chest while gradually elevating the head, heart and shoulders of an individual from a starting elevation angle to a final elevation angle greater than zero degrees relative to horizontal;
regulating the intrathoracic pressure of the individual while performing the CPR; and
after stopping the performance of chest compressions, promptly lowering the head, heart, and shoulders from the final elevation angle within a clinically-desirable timeframe selected to prevent significant reduction in brain blood flow until the head, heart and shoulders are lowered,wherein the clinically-desirable timeframe is between about 1 and 60 seconds.

Abstract
A method for performing cardiopulmonary resuscitation (CPR) includes elevating the head, heart and shoulders of an individual from a starting elevation angle to a final elevation angle greater than zero degrees relative to horizontal while performing CPR by repeatedly compressing the chest. The method includes elevating the brain within a time period selected to be slow enough to permit a sufficient amount of blood to flow to the brain throughout the elevation time period. The method also includes regulating the intrathoracic pressure of the individual while performing CPR. The performance of chest compressions is stopped and after stopping the performance of chest compressions, the head, heart, and shoulders are promptly from the final elevation angle within a timeframe selected to prevent significant drainage of blood from the brain until the head, heart and shoulders are lowered.

12. A method for performing cardiopulmonary resuscitation (CPR), comprising:
-
performing CPR by repeatedly compressing the chest while gradually elevating the head, heart and shoulders of an individual from a starting elevation angle to a final elevation angle greater than zero degrees relative to horizontal to actively drain venous blood from the brain using gravity, whereby elevation of the head, heart and shoulders assists to lower intracranial pressure and increase cerebral perfusion pressure during the performance of the CPR, wherein the head, heart and shoulders are elevated from the starting elevation angle to the final elevation angle within a clinically-desirable timeframe selected to enable enough blood flow to the brain even though the brain is being elevated; regulating the intrathoracic pressure of the individual while performing CPR to create a negative pressure within the chest during a relaxation phase of CPR; and after stopping the performance of chest compressions, promptly lowering the head, heart and shoulders from the final elevation angle within a lowering timeframe selected to prevent significant drainage of blood from the brain until the head, heart and shoulders are lowered; wherein the lowering timeframe is between about 1 and 60 seconds. - View Dependent Claims (13, 14, 15, 16, 17)
