Lancashire Objective Volume Evaluation of Leg Oedema in Heart Failure Second Pilot

The Heartfelt device uses a system of scanner in a compact device to generate depth 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, For the measurements to take place, the participant walks in the field of view of the device, measurments are only taken when the patients has bare feet and no slippers/shoes, so the location of the device in the home is choosen to match this requirement. Participants are not expected to change anything to their routine. The device can also take measurements in the dark.

"The participant will be instructed to use those scales for the period of the study, as often as directed by their healthcare professional. The weighing scales display weight so that the participants can record the weight in their own heart failure records if they wish to do so.~The scales will communicate with the Personal Computer (PC) contained in the Heartfelt device and the data will be sent to the Heartfelt server through an encrypted link.~The data from the scales will be reviewed retrospectively, as the comparison in this study is with standard care, not with enhanced provision of care, which would be the case if we were using automatic reporting of weights."
