A method for performing CPR with a mobile defibrillator (AED) unit can include detecting, via an application on a user device, a connection of a mobile AED unit to the user device; detecting, via the application, that pads have been attached to a subject, the pads comprising at least one accelerometer; recording, via the application, EKG measurements of the subject made by the pads; receiving accelerometer data from the at least one accelerometer; analyzing the accelerometer data to determine a breathing pattern of the subject; and based on the determined breathing pattern, initiating a CPR protocol.

An elevation device used in the performance of cardiopulmonary resuscitation (CPR) and after resuscitation includes a base and an upper support operably coupled to the base. The upper support is configured to elevate an individual's upper back, shoulders and head. The elevation device also includes a chest compression device coupled with the base. The chest compression device is configured to compress the chest and to actively decompress the chest.

According to an aspect, there is provided a cardiopulmonary resuscitation, CPR, device (1) for enhancing the delivery of CPR to a patient. The device (1) comprises: a patient side (3) for engagement with the chest of the patient; and a user side (2) for engagement with the hands of a user delivering CPR to the patient. One or more of the surface of the patient side (3) and the surface of the user side (2) is at least partially formed of a material with variable contact characteristics configured to be controlled so as to regulate the lateral force distribution profile at the one or more of the surface of the patient side (3) and the surface of the user side (2) from a force applied to the device (1) by the user and transferred through the device (1) to the patient. According to other aspects, there is provided a control method for a cardiopulmonary resuscitation, CPR, device and a computer program which, when executed on a computing device, carries out a control method for a cardiopulmonary resuscitation, CPR, device.

Systems and methods related to the field of cardiac resuscitation, and in particular to devices for assisting rescuers in performing cardio-pulmonary resuscitation (CPR) are described herein. The system includes a camera to capture one or more images at a scene where the person in need of medical assistance is being treated and one or more processors. The processors receive and process the images, by using a rescuer profile, to provide a real-time feedback to the rescuer to improve the CPR treatment.

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.

A chest compression device with a chest compression belt assembly including guards and sensors operable with a control system to control operation of the system depending on detection of proper installation of the guards.

A method for performing cardiopulmonary resuscitation (CPR) includes elevating the head, heart and shoulders of an individual from a starting elevation angle to a final elevation angle greater than zero degrees relative to horizontal while performing CPR by repeatedly compressing the chest. The method includes elevating the brain within a time period selected to be slow enough to permit a sufficient amount of blood to flow to the brain throughout the elevation time period. The method also includes regulating the intrathoracic pressure of the individual while performing CPR. The performance of chest compressions is stopped and after stopping the performance of chest compressions, the head, heart, and shoulders are promptly from the final elevation angle within a timeframe selected to prevent significant drainage of blood from the brain until the head, heart and shoulders are lowered.

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.

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 the 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 is 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 is further configured to transition from the latch-closed configuration to the latch-open configuration when the lock component of the base member impacts an external portion of the clamp mechanism without the release mechanism being pulled away from the base member.
