## 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

### Claim 1

A method, comprising:
performing CPR with at least the head of an individual elevated by bending the individual at the waist to at least 20 degrees relative to horizontal while the individual's legs are generally aligned with a horizontal plane, wherein CPR is performed with an automated device that compresses the chest while the head is elevated; and
interfacing a device for regulating the intrathoracic pressure with the individual:
wherein the automated device includes a band that is positioned around the thorax of the individual;
wherein the band around the thorax tightens with each compression and relaxes with each decompression, and
wherein the band around the thorax tightens when at least the head is elevated.

### Claim 2 (depends on 1)

The method of claim 1, wherein CPR is performed with the individual's head and shoulders up, or with the individual's body and shoulders tilted up.

### Claim 3 (depends on 1)

The method of claim 1, further comprising measuring intrathoracic pressure or an indicator of intrathoracic pressure and adjusting the amount of intrathoracic pressure on a beat by beat basis based on a measured intrathoracic pressure so as to not exceed a given level when in the 0 degree supine position but allowing for more pressure and thus greater forward blood flow in a position with the individual's head elevated.

### Claim 4 (depends on 1)

The method of claim 1, further comprising coupling a pressure-actuated valve to the individual's airway to create a negative pressure in the chest to help increase circulation by refilling the individual's heart with venous blood during a decompression or chest recoil phase of CPR.

### Claim 5 (depends on 1)

The method of claim 1, wherein the automated device with the band includes a mechanism to actively decompress the chest.

### Claim 6 (depends on 5)

The method of claim 5, wherein the mechanism to actively decompress the chest comprises a suction cup.

### Claim 7 (depends on 1)

The method of claim 1, wherein CPR is performed when the patient is supine, with the automated device with the band around the thorax; and
wherein when the patient's head is an elevated position the band is tightened either manually or in an automated manner so that with each compression the thorax is circumferentially compressed; and
wherein with each decompression the thorax is allowed to completely recoil or decompress without any resistance from the band.

### Claim 8 (depends on 1)

The method of claim 1, wherein some circumferential pressure by the band is applied when the patient is supine and more is applied when the head is upright.

### Claim 9 (depends on 5)

The method of claim 5, wherein the mechanism includes an adhesive pad that is attached to the chest, allowing for active chest compression and active chest decompression.

### Claim 10

A method for performing cardiopulmonary resuscitation (CPR), comprising:
elevating one or both of the torso and head of an individual to an angle of at least twenty degrees as measured between a surface that supports at least a portion of the torso and a level reference surface to lower intracranial pressure and increase cerebral perfusion pressure;
repeatedly compressing the individual's chest while the individual's torso or head is elevated and while the individual's legs are generally aligned with a horizontal plane;
interfacing a device for regulating an intrathoracic pressure with the individual; and
regulating the intrathoracic pressure of the individual while performing CPR to create a negative pressure within the chest during a release phase of CPR.

### Claim 11 (depends on 10)

The method of claim 10, further comprising elevating the torso or the head and shoulder of the individual to an angle less than or equal to about ninety degrees.

### Claim 12 (depends on 10)

The method of claim 10, further comprising elevating the head, head and shoulders, or head and torso of the individual to an angle selected from a range between about fifteen degrees to about thirty degrees.

### Claim 13 (depends on 10)

The method of claim 10, further comprising elevating the torso of the individual by manual adjustment of the surface that supports at least the portion of the torso to bend the individual at the waist.

### Claim 14 (depends on 10)

The method of claim 10, further comprising elevating the torso of the individual by automated adjustment of the surface that supports at least the portion of the torso to bend the individual at the waist.

### Claim 15 (depends on 10)

The method of claim 10, further comprising performing a standard CPR procedure on the individual.

### Claim 16 (depends on 10)

The method of claim 10, further comprising performing a stutter CPR procedure on the individual.

### Claim 17 (depends on 10)

The method of claim 10, further comprising performing at least one of: an active compression decompression CPR; a thoracic band with phased CPR; an automated CPR device that performs CPR according to a pre-determined algorithm.

### Claim 18 (depends on 10)

The method of claim 10, further comprising:
positioning a mechanical CPR device relative to the individual's chest; and
activating the mechanical CPR device to perform a mechanized CPR procedure on the individual.

### Claim 19

A method for performing cardiopulmonary resuscitation (CPR), comprising:
elevating one or both of the torso and head of an individual to an angle of at least twenty degrees as measured between a surface that supports at least a portion of the torso and a level reference surface to lower intracranial pressure by bending the individual at the waist;
interfacing a pressure regulation device with the individual to create a negative pressure within the chest during a release phase of CPR;
providing intermittent positive pressure ventilation; and
repeatedly compressing the chest while interfacing the pressure regulation device with the individual while one or both of the torso and head is elevated and while the individual's legs are generally aligned with a horizontal plane to increase the individual's perfusion pressure while reducing or lowering intracranial pressure.

### Claim 20 (depends on 1)

The method of claim 1, wherein the tension on the band varies depending on the position of the head.
