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.

A CPR device having a base member configured to be placed underneath a patient, a chest compression mechanism configured to deliver CPR chest compressions to the patient, a support leg configured to support the chest compression mechanism at a distance from the base member, a clamp mechanism coupled to the support leg, and a release mechanism coupled to the support leg and the clamp mechanism. The clamp mechanism is configured to attach the support leg to a lock component of the base member in a latch-closed configuration and to release the support leg from the lock component in a latch-open configuration. The clamp mechanism is further configured to transition from the latch-closed configuration to the latch-open configuration when the lock component of the base member impacts an external portion of the clamp mechanism without the release mechanism being pulled away from the base member.

A device for delivering chest compressions for performing cardiopulmonary resuscitation includes a compression assembly and chest contact pad that can be positioned over the thorax of a patient experiencing a cardiac arrest. The compression assembly is supported by a frame and one or more positioning mechanisms for moving the compression assembly relative to the patient's left ventricle. A controller causes the compression assembly to deliver a plurality of chest compressions to the patient. A blood flow monitor, such as a Doppler ultrasound monitor, is coupled with the patient's femoral or carotid artery to monitor the flow of arterial blood when chest compressions are delivered and to communicate blood flow parameter information to the controller. The controller causes the positioning mechanism to move the location where the compressions are delivered to optimize the blood flow parameters. The controller monitors the blood flow parameters to determine the occurrence of a return to spontaneous circulation (ROSC). When ROSC is detected, the controller causes the compression assembly to cease chest compressions.

A back plate for use with a CPR compression device can include first and second static attachment elements configured on first and second sides, respectively, to releasably connect to first and second legs, respectively. In addition, a bottom surface of the back plate can include a plurality of ribs that run from the first side to the second side in parallel to the third and fourth sides. The back plate also includes a hollow portion between the upper and bottom surfaces and the first, second, third, and fourth sides, and the ribs and third and fourth sides provide structural rigidity to the back plate. A plurality of openings along the third and fourth sides may be configured for strapping the back plate to a patient. Grooves may be configured on the top surface to hide sink marks on the top surface caused by the ribs on the bottom surface.

Systems, devices and methods for providing active and/or passive compression therapy to a body part can include a compression device worn over a compression stocking. The compression device can have a pulley based drive train that is driven by a motor to tighten and loosen compression elements, such as compression straps, in a precise, rapid, and balanced manner. Sensors can be used in the compression device and/or compression stockings to provide feedback to modulate the compression treatment parameters.

An autonomous mechanical CPR device and method is disclosed for adjusting the therapeutic position of a CPR surface during a CPR session. The adjustment of the CPR surface permits the CPR surface to maintain better proximity to a victim's chest.

The invention provides, in some aspects, a coupler for inline connection of two bodies where one of the bodies provides linear motion to the other. Further aspects of the invention provide such a coupler comprising a first adapter linearly engaging a second adapter in a capture B. The first adapter defines a capture C for temporarily securing a first compatible body, and the second adapter defines a connector for securing a second compatible body. The capture B and the connector are oriented one to the other such that linear movement of the first compatible body translates into linear movement of the second compatible body. The capture B releases the secured compatible body upon pressing together of the first and second adapter. In a particular embodiment, a coupler of the type described above joins a compression module of a mechanical CPR device to a patient interface of that device.

A support surface having a plurality of small, independent, cylinder shape, vertically mounted air cells integrated on a hospital bed, nursing home or home care beds or as a mattress replacement. The pneumatic support surface is electronically controlled and operated by a caregiver through the only external part of the system: a smartphone or a tablet. The support surface is capable to perform separately or in succession, within two hours, several cycles of a plurality of known procedures for the prevention of pressure sores plus a unique procedure focused on the most-risky parts of the body combined with a program that provides optimum conditions for best and faster healing of existing pressure injuries.

A CPR chest compression device with a cooling exhaust flow path configured to direct cooling air flow through the device. A CPR chest compression device with a battery retainer interoperable with the control system to provide for controlled shut-down when an operator attempts to remove the battery during operation.

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.
