Abstract: A device for applying compressions to a chest of a patient has a suction cup configured to contact the chest of the patient. The device also has a valve configured to allow air to exit or to enter a cavity through a boundary of the suction cup, the cavity being between the suction cup and the chest of the patient, and the device has a pump configured to evacuate the cavity through the valve.

Abstract: An adjustable-size backboard for a chest compressions device having a first connector, a second connector, and an adjustable elongated portion extending between the first connector and the second connector. The first connector is structured to attach to a first leg of a chest compression device. The second connector is structured to attach to a second leg of the chest compression device. The adjustable elongated portion includes a first portion that extends from the first connector and a second portion. The second portion is between the first connector and the second connector and is structured to slide relative to the first portion.

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: 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: 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.
