1. A method for performing cardiopulmonary resuscitation (CPR), comprising:
- elevating the head, heart, and shoulders of an individual to an angle of between about 30 degrees and about 60 degrees relative to horizontal by bending the individual at the waist to actively drain venous blood from the brain using gravity while performing CPR by repeatedly compressing the chest, whereby elevation of the head, heart, and shoulders assists to lower intracranial pressure, increase cerebral perfusion pressure, and reduce venous blood concussion pressure waves directed to the brain during the performance of CPR, andinterfacing a device with the airway of the individual to regulate the intrathoracic pressure of the individual while performing CPR to create a negative pressure within the chest during a relaxation phase of CPR.

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.

7. A method for performing cardiopulmonary resuscitation (CPR), comprising:
-
elevating the head, heart, and shoulders of an individual to an angle of between about 30 degrees and about 60 degrees relative to horizontal to actively drain venous blood from the brain using gravity and to lower intracranial pressure; interfacing a chest compression device to the chest of the individual; interfacing an impedance threshold device with the airway of the individual to create a negative pressure within the chest during a relaxation phase of CPR; and performing active compression/decompression CPR using the chest compression device while the head, heart, and shoulders are elevated; whereby elevation of the head, heart, and shoulders assists to lower intracranial pressure, increase cerebral perfusion pressure, and reduce venous blood concussion pressure waves directed to the brain during the performance of CPR. - View Dependent Claims (8, 9, 10, 11, 12, 13, 14)

15. A method for performing cardiopulmonary resuscitation (CPR) that involves a chest compression phase and a relaxation phase, comprising:
-
elevating the head, heart, and shoulders of an individual to an angle of elevation between about 30 degrees and about 60 degrees as measured relative to horizontal by bending the individual at the waist to actively drain venous blood from the brain using gravity and to lower intracranial pressure; interfacing an impedance threshold device with the airway of the individual to create a negative pressure within the chest during the relaxation phase of CPR; providing intermittent positive pressure ventilation; and repeatedly compressing the chest while interfacing the impedance threshold device with the airway and while the head, heart, and shoulders are elevated to increase the individual'"'"'s perfusion pressure while reducing or lowering intracranial pressure. - View Dependent Claims (16, 17)
