Abstract: Techniques for pairing medical devices are described. An example method includes detecting a signal indicating a physiological parameter of a subject and determining, by analyzing the signal, that a second medical device is administering a treatment to the subject. In response to determining that the second medical device is administering the treatment to the subject, the method further includes pairing a first medical device with the second medical device. In response to pairing the first medical device with the second medical device, the method further includes transmitting data to the second medical device over a wireless channel.

Abstract: In embodiments, a CPR chest compression system includes a retention structure that can retain the patient's body, and a compression mechanism that can perform automatically CPR compressions and releases to the patient's chest. The compression mechanism can pause the performing of the CPR compressions for a short time, so that an attendant can check the patient. The CPR system can include a user interface that can output a human-perceptible check patient prompt, to alert an attendant to check the patient during the pause. The compression mechanism can during a CPR session retreat a distance away from the patient's chest whereby the patient's chest can expand without active decompression of the patient's chest beyond the chest's natural resting position.

Abstract: Techniques for administering therapy and monitoring a subject based on communication between medical devices are described. An example method includes receiving, by an external defibrillator, data from a mechanical chest compression device that is administering chest compressions to a subject, determining, by the external defibrillator analyzing the data, a control parameter for controlling administration of a therapy to the subject by the external defibrillator, and administering, by the external defibrillator, the therapy to the subject in accordance with the control parameter.

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: An active backboard that can assist with adjusting a patient on the backboard to ensure that the backboard is correctly aligned for a compression mechanism of an upper portion of a mechanical cardiopulmonary resuscitation (CPR) device to perform compressions. The active backboard can also include multiple layers that can slide or move relative to each other to move the patient relative to the backboard. The active backboard can include roller bars, a wheel, and/or projections to assist with moving a patient relative to the backboard.

Abstract: Techniques and devices for extending a piston and/or compression unit, 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, some aspects, the piston includes sleeves which can move relative to each other to extend the piston. In additional aspects, the compression mechanism may also extend downward toward the patient. 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.

Abstract: Examples of the disclosure are directed to adjustable back plates or backboards for a mechanical compression device to accommodate different patient sizes and/or for ease of storage. Examples of the disclosure includes back plates that can be folded, pieced together, or otherwise have a variable distance between connectors that attach to legs of a chest compression device. Examples also include back plates which may have two sides, such as an adult patient side and a pediatric patient side, to accommodate different patient sizes.

Abstract: Examples of the disclosure are directed to mechanical compression devices that can adjust a location of a compression position relative to a patient. One or more of the mechanical compression devices can adjust the compression position in an adjustment plane that is generally perpendicular to a patient. Some of the mechanical compression include support columns that have actuators that can be set asymmetrically to adjust the compression position and/or can be tilted relative to the backboard to adjust the compression position. Other examples includes mechanical compression devices that have multiple actuators that can be used to adjust the compression position as well as provide compressions.

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: A CPR chest compression machine includes a retention structure configured to retain a patient's body, and a compression mechanism configured to perform automatically CPR compressions to the patient's chest. The CPR machine also includes a camera coupled to the retention structure or to the compression mechanism. The camera has a field of view that spans at least a certain portion of the patient's body, and is configured to acquire an image of what is spanned by its field of view. The image may be stored in a memory, displayed, transmitted, analyzed to diagnose the patient, detect shifting of the patient within the CPR machine, etc.
