Abstract

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 patient side (3) and the user side (2) is at least partially formed of a non-Newtonian fluid, the viscosity of which is configured to vary in response to the application of energy so as to regulate a force distribution profile of the device (1) 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.
