Described herein are various embodiments of systems and devices operable to detect individual oxygen delivery events at a user body region which are associated with external oxygen boluses administered to a user. Such devices and system may be useful, for example, in assessing the efficacy of cardiopulmonary resuscitation (CPR) or intubation.

A distributed patient monitoring system comprises at least one standalone portable ultrasound imaging unit configured to be fixed to a stable position against the skin on a patient's body and capable of prolonged ultrasound data acquisition, including an ultrasound imaging array, transmit-receive circuitry, a beamformer, backend signal and image processing subsystem, power and communication subsystems, and a monitoring workstation connected to each standalone portable ultrasound imaging unit configured to request and receive ultrasound imaging information from each standalone portable ultrasound imaging unit, and configured to analyze and display acquired ultrasound information.

A method for performing cardiopulmonary resuscitation (CPR) includes elevating the heart of an individual to a first height relative to a lower body of the individual. The lower body may be in a substantially horizontal plane. The method may also include elevating the head of the individual to a second height relative to the lower body of the individual. The second height may be greater than the first height. The method may further include performing one or more of a type of CPR or a type of intrathoracic pressure regulation while elevating the heart and the head. The first height and the second height may be determined based on one or both of the type of CPR or the type of intrathoracic pressure regulation.

Disclosed herein is a resuscitation device facilitating the administration of cardiopulmonary resuscitation to a subject, the resuscitation device comprising a housing having a top surface and a bottom surface, said top surface having a concave dell configured to guide on the top surface a hand positioning of a rescuer administrating a cardiopulmonary resuscitation to a subject, and said bottom surface configured to position and stabilize the housing over a sternum of the subject, and wherein the housing is configured to transmit a uniform distribution of the cardiopulmonary resuscitation force to the chest of the subject, said uniform distribution facilitates distributing the cardiopulmonary resuscitation force over a surface area that greater than the area of the top surface that directly receives the cardiopulmonary resuscitation force, thereby facilitating injury and contusion prevention to ribs and the sternum of the subject.

A portable automated life-saving system, comprising one or more sensors utilized for collecting data related to a patient's current medical condition and to transmit the collected data to a main computer; a main computer adapted with suitable hardware and software to process data, received from the one or more sensors, with respect to predefined medical conditions and corresponding life-saving treatment protocols, thereby to determine an initial life-saving treatment protocol to be delivered to the patient, and accordingly to operate a main controller configured to activates corresponding life-saving devices; a main controller adapted to be operated by the main computer, for controllably activating fastening means, and for controllably activating one or more life-saving devices for delivering life-saving treatment to the patient; two or more fastening means, controllably activated by the main controller for obtaining a firm attachment of the automated life-saving system to a patient; one or more life-saving devices controllably activated by the main controller for delivering life-saving treatment to the patient; one or more batteries. The portable automated life-saving system continuously monitors the evolving medical condition of a patient, and correspondingly adapts the given treatment, namely, the operation of the one or more life-saving devices.

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.

Ventilator enables operator to enter into the microprocessor estimate of a patient's individual characteristic, such as weight, which the microprocessor uses to control delivered tidal volume and other parameters to match the patient. The operator can select one of several ventilator operational modes (intube, mask, CPR). Sensors input data to the microprocessor to maintain parameter optimizations and accuracy. Visual/audible alarms and tools activate when one or more parameters exceed or fail to exceed predetermined values for patient's weight. Manual over-ride is available. The ventilator has a quick start capability in which the operator turns on power, selects the automatic operating mode, enters patient's characteristic, selects control option starting automatic ventilation of proper volumes inhalation/exhalation periods, pressure, and oxy-air mixture.

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.
