Abstract: A system for improving cardiac output of a patient suffering from pulseless electrical activity or shock and yet displays myocardial wall motion including: a sensor to detect myocardial activity to determine the presence of residual left ventricular pump function having a contraction or ejection phase and a filling or relaxation phase, a device to prompt the application of or apply a compressive force repeatedly applied to the chest based on the sensed myocardial activity such that the compressive force is applied during at least some of the ejection phases and is ceased during at least some of the relaxation phases to permit residual cardiac filling, thereby enhancing cardiac output and organ perfusion.

Abstract: A computer-implemented method for communicating information to medical responders includes registering a plurality of individuals as potential responders for medical problems, receiving at a central service an indication that a person is having a medical problem and receiving information that identifies a current location of the person, and identifying, from among the registered plurality of individuals, one or more registered individuals who are currently in close proximity to the person having a medical problem. The method also includes transmitting, to the one or more registered individuals, information that identifies the location of the person having a medical problem. The one or more individuals comprise lay responders who are not assigned responsibility to provide lifesaving services in an area around the current location of the person.

Abstract: A method for improving the cardiac output of a patient who is suffering from pulseless electrical activity or shock and yet still displays some myocardial wall motion including sensing myocardial activity to determine the presence of residual left ventricular pump function having a contraction or ejection phase and a filling or relaxation phase. In such cases, a compressive force is repeatedly applied to the chest based on the sensed myocardial activity such that the compressive force is applied during at least some of the ejection phases and is ceased during at least some of the relaxation phases to permit residual cardiac filling, thereby enhancing cardiac output and organ perfusion. Also incorporated may be a logic circuit capable of utilizing multiple sensing modalities and optimizing the synchronization pattern between multiple phasic therapeutic modalities and myocardial residual mechanical function.

Abstract: A chest compression monitor for measuring the depth of chest compressions achieved during CPR. A displacement detector produces a displacement signal indicative of the displacement of the CPR recipient's chest toward the recipient's spine. A signaling mechanism provides chest compression indication signals prompting a CPR provider to provide a chest compression force at a desired depth and rate. The device is held to the dorsal surface of the hand during use and provides a display for feedback, which is readily visible to the CPR provider.

Abstract: A self-operated non-contact tonometer for measuring the intra-ocular pressure of an eye, projecting light into the eye and measuring the reflected light as affected by mechanical distortion. The cornea is distorted by delivering a pneumatic pulse. The tonometer consists mainly of an electro-optical unit mountable on the head of a user and a control unit. The control unit of the tonometer includes a display and optionally an audio device for instructing the user. The electro-optical unit employs a tubular wave guide, a light detector, and a reflector for deflecting a light beam to the eye and for eliminating a part of the reflected light reaching the detector. The aligning of the tonometer with the head of the user is optionally assisted by a reticle.

Abstract: A smart electronic communications network comprised of clinicians and experts designed for the purpose of answering diagnostic and clinical questions and queries posed by subscribers and participants in of the network.

Abstract: A computer-implemented method for managing rescue training includes registering a plurality of individuals as potential rescue trainees through a central computer server system, receiving from computing devices that are remote from the central server system information indicative of rate and depth of compression for ones of the potential rescue trainees, and generating comparative data that reflects performance of CPR chest compressions for a first rescue trainee against other rescue trainees. The method also includes providing the comparative data over a network for review by one or more of the rescue trainees.

Abstract: A resuscitation device for assisting a rescuer in resuscitating a patient. A handheld computing/communication device may be configured for performing a non-resuscitation function during time periods when resuscitation is not required, the handheld device may be further configured to provide CPR prompts during time periods when used by a rescuer to assist in resuscitation, and a sensor may be provided to measure a parameter (e.g., chest acceleration) relevant to resuscitation. A CPR-assistance element may be configured to be applied to the patient and to communicate with the handheld computing/communication device.

Abstract: Material is fed into a revolving drum which has an interior configuration, preferably in the form of a helical blade, to convey the material at a controlled rate through the drum. A low temperature gas, such as nitrogen, is introduced into the drum downstream when viewed in the direction of travel of the material, in a liquid state at a controlled rate through a spray nozzle system, thereby continuously exposing the material to the cooling effect of the gas. A portion of the gas is recirculated from the upstream end to the downstream end of the drum. The material is pre-cooled in the upstream portion of the drum. After exiting from the drum, the material may be crushed or impacted and separated.
