Abstract: A medical device for caring for a patient includes a patient utility for measuring a patient parameter or administering a therapy to the patient and an alarm system that has a receiver to accept status information about the medical device. A use detector of the alarm system is structured to determine when the medical device is being prepared for use and a status detector of the alarm system is adapted to determine from the status information that the medical device is in a ready state. The alarm system further includes an alarm that is activated when the medical device is both being prepared for use and not in the ready state. This description also includes methods of generating an alarm when the medical device is both being prepared for use and not in the ready state.

Abstract: 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 a 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 may be 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 may further be configured to transition from the latch-closed configuration to the latch-open configuration when the lock component of the base member impinges upon an external portion of the clamp mechanism.

Abstract: A medical device for indicating a chest compression depth, including a first electrode assembly structured to be disposed on a chest of a patient, a second electrode assembly structured to be disposed on a back of the patient, and a processor configured to determine a chest compression depth as a proportion of chest height based on a first impedance measurement between the first electrode assembly and the second electrode assembly when the chest is not compressed and a second impedance measurement between the first electrode assembly and the second electrode assembly when the chest is compressed.

Abstract: An AED trainer is implemented using a special purpose hardware platform and a state machine, implemented in software, which together replicate or simulate operations of a target AED device. The state machine operates the AED trainer in an efficient and effective manner to train students to correctly perform rescue procedures on patients suffering from Sudden Cardiac Arrest.

Abstract: An adjustable chest compression device that can adjust to accommodate a variety of patient sizes. The chest compression device can include adjustable support legs structured to support the chest compression mechanism at a distance from the base member and adjust to accommodate a patient size. Another adjustable chest compression device can include adjustable legs that can adjust to accommodate different patient sizes, as well as perform the chest compressions using the adjustable legs. An extension, such as a back plate and/or leg extension can be added to a chest compression device to make the chest compression device taller and/or wider to accommodate larger patients.

Abstract: Disclosed systems and methods include electronic devices attached to a patient or object that transmit data to other devices over a secure communication channel. The devices can track and/or monitor object(s) and/or patient(s) and transmit the tracked and/or monitored data to other electronic devices. Such data can include monitored patient physiological parameter(s) received and/or sensed by the device, for example. A master of the two devices transmits a communication signal to another device that, in response, initiates a secure wireless communication channel, causes one or more modules on the device to be powered, and, when powered, transmits the tracked and/or sensed physiological data over the secure wireless communication channel to the master device. Some example master devices transmit the communication signal with an instruction to the device to activate an onboard power source that later may be disconnected after the tracked and/or physiological data is transmitted.

Abstract: A portable medical device having improved ECG trace display and reporting. Embodiments implement features to ameliorate artifacts created by virtue of attempting to eliminate compression artifacts due to mechanical compression devices. Other embodiments additionally implement features to seek to detect the occurrence of ROSC while chest compressions are ongoing.

Abstract: A CPR machine (100) is configured to perform, on a patient's (182) chest, compressions that alternate with releases. The CPR machine includes a compression mechanism (148), and a driver system (141) configured to drive the compression mechanism. A force sensing system (149) may sense a compression force, and the driving can be adjusted accordingly if there is a surprise. For instance, driving may have been automatic according to a motion-time profile, which is adjusted if the compression force is not as expected (850). An optional chest-lifting device (152) may lift the chest between the compressions, to assist actively the decompression of the chest. A lifting force may be sensed, and the motion-time profile can be adjusted if the compression force or the lifting force is not as expected.

Abstract: A portable medical device having an intravenous line flow sensor integrated into a cable. The portable medical device may be a defibrillator having an ECG or electrode cable couple to ECG or electrode leads. The flow sensor may be integrated into the ECG or electrode cable. The portable medical device uses the flow sensor to capture and store information about fluids delivered to a patient being treated with the portable medical device. The information may include total volume provided, flow rate, and the like. The information may then be used to evaluate the treatment provided to the patient.

Abstract: Techniques and devices for extending a piston, for example connected to a medical device such as a mechanical CPR device, to accommodate different sized patients, are described herein. In some cases, a piston of a mechanical CPR device may include an inner piston at least partially slidable into an external piston sleeve. In one aspect, an external piston spacer may be attached to an outward surface of the inner piston to extend the length of the piston. In another aspect an internal bayonet sleeve may contact one or more locking rods at various positions, enabling adjustment of the length of the inner piston. In yet another aspect, a piston adapter may be removably attached to the end of the piston. In all aspects, the change in length of the piston may be detected and used to modify movement of the piston, for example to more safely perform mechanical CPR.

The controller can be configured to cause the driver during a session to perform at least two cycles of negative pressure ventilation, each of the at least two cycles of negative pressure ventilation including positioning the piston at a reference position, retracting the piston from the reference position to an expansion position to expand a chest of a patient to generate negative pressure ventilation, and returning the piston from the expansion position to the reference position.

Abstract: A prehospital telemedicine system comprises a physiologic monitor; an electronic patient care reporting system (ePCR) system; and a point-of-care blood analyzer communicatively coupled to the physiologic monitor and the ePCR system. The point-of-care blood analyzer is configured to perform an analysis of a blood sample based on an indication of a need for a specific blood analysis provided by one of the physiologic monitor and the ePCR system, and to automatically transmit a result of the analysis to a remote data receiving system. The indication of a need for a specific blood analysis may be based upon any one of the following: vital signs data obtained for a patient by the physiologic monitor; and/or current documentation or past medical history captured on or available through the ePCR system.
