A CPR chest compression system includes a retention structure that retains the body of a patient, and a motor and a compressor that can perform CPR compressions to the chest of the patient. The motor is powered by a battery that is located on the retention structure but away from the motor, and is electrically connected to the motor via one or more wires. Accordingly the weight and volume of the battery can be located away from a top portion of the retention structure. This renders the CPR system is less heavy at the top, and therefore less likely to tilt and start compressing the chest at a different point. Moreover, this permits X-Rays of a larger footprint to go through the CPR system and reach the patient, in embodiments where the components are transparent to X-Rays.

Medical devices, plug-ins, systems, and methods for CPR quality feedback are disclosed. The medical devices can calculate peripheral circulation relevant parameters based on measured signals containing at least partial hemodynamic characteristics. Amplitude and area characteristics included in the peripheral circulation relevant parameters can further be determined for providing feedback and control relating to CPR quality during the compression process. Also, compression interruption during CPR can be evaluated based on a pulse waveform generated from the measured signals.

A CPR apparatus includes a chest compression unit and a means for mounting the chest compression unit on a patient. The chest compression unit includes a plunger disposed in a housing. At its one end extending from the housing the plunger has a compression member. The plunger is driven in a reciprocating manner by a reversible electromotor via a mechanism for translating rotational motion to linear motion or by a linear induction electromotor. The chest compression unit includes an electromotor control unit including a microprocessor, a first monitor for monitoring the position of the plunger in respect of the housing and a second monitor for monitoring the position of the plunger in respect of the mechanism for translating rotational motion to linear motion or the rotor of the linear induction electromotor. The monitored positions are communicated to the electromotor control unit. Also disclosed is a corresponding CPR method.

A system for electrical ventilation stimulation of a patient including an implantable nerve stimulator including a stimulation circuit and a pulse generator that produces biphasic charge-balanced pulses to stimulate a phrenic nerve, an external digital programming device having near field communication transmission and a digital interface, and wherein the external digital programming device is used to control settings of the implantable nerve stimulator.

An alignment device for assisting a rescuer for correctly aligning a mechanical cardiopulmonary resuscitation (CPR) device. The alignment device can guide positioning of the backboard so that the backboard is correctly positioned prior to connecting an upper portion of the mechanical CPR device to the backboard. The alignment device can also include positioning the mechanical CPR device without a backboard or positioning the backboard and the upper portion of the mechanical CPR device nearly simultaneously.

Embodiments of the present concept are directed to CPR chest compression machines that include a sensor to detect a parameter about a patient, such as an indication of patient recovery, and include a processor that determines whether to cease series of successive compressions on the patient in response to the detected parameter.

A system for electrical ventilation stimulation of a patient including an implantable nerve stimulator including a stimulation circuit and a pulse generator that produces biphasic charge-balanced pulses to stimulate a phrenic nerve, an external digital programming device having near field communication transmission and a digital interface, and wherein the external digital programming device is used to control settings of the implantable nerve stimulator.

A method for cardiopulmonary resuscitation (CPR) includes supplying an inflation gas at an operative pressure to an inflation actuated soft gripper device to change form from an undeployed state to a deployed grip state that accommodates and grips a human torso. The inflation actuated soft gripper device includes a first inflatable gripper arm having a first distal end and a second inflatable gripper arm having a second distal end. The first distal end and the second distal end approach one another from the undeployed state to the deployed grip state. The first and second distal ends are spaced apart from one another further in the undeployed state than in the deployed grip state. An actuator power and a CPR control signal are delivered to a CPR pressure application device to cyclically extend and retract a pressure applicator along an axis in alignment with a sternum of the human torso.

Automated CPR systems incorporating biological feedback can include an automated compression piston system, a data acquisition system, computer systems for running various control algorithms, ventilation control systems, and/or drug delivery systems. Automated CPR systems can be used as stand-alone systems for treating patients in cardiac arrest, or they can be used to administer pretreatment to a patient prior to defibrillation.

An improvement to portable cardiopulmonary resuscitation (CPR), includes a first module hub housing, an inflation actuated soft gripper configured to receive an inflation gas in response, to change form to a deployed grip state that accommodates and grips a human torso. Improvements include the inflatable gripper not requiring lifting the patient. Improvements also include modularity for in-the-field reconfigurability, in which a second module hub housing attaches to the first module hub housing, carrying a CPR pressure applicator configured to receive an actuator power and control signal causing, concurrent with the deployed grip state, cyclic extension and retraction of a pressure applicator along an axis aligned with a sternum of the human torso.
