Lancashire Objective Volume Evaluation of Leg Oedema in Heart Failure

"The Heartfelt device uses a system of cameras in a compact device to generate 3D images of the feet and lower legs with a view to detecting early volume changes. The device can be installed on the wall or as a free standing unit; however, given the COVID-19 pandemic, only the free standing option will be available to participants, so as to avoid the necessity of an installer visiting the patient. For the measurements to take place, the participant walks in the field of view of the device. Participants are not expected to change anything to their routine. The device can also take measurements in the dark.~The switch between 'full data analysis' and 'technical checks only' modes can be done remotely, making the cross-over seamless.~In the event that an alert is generated by the device, a medical assessment will take place either by phone or face to face appointment to evaluate the participant's condition."
