Abstract: The present invention describes a device for assessing and providing quality feedback on thoracic compressions during cardiopulmonary resuscitation, which allows for an optimal assessment of the quality of the thoracic compressions made during cardiopulmonary resuscitation, which provides feedback on the position of said compressions. The device for assessing and providing quality feedback on thoracic compressions during cardiopulmonary resuscitation, by means of the elements thereof together with essential technical features thereof, such as an infrared sensor, a microprocessor, logic means, a graphic interface and remote connectivity means, makes it possible to estimate the depth and frequency parameters of the thoracic compressions, in order to determine whether they are adequate during a cardiopulmonary resuscitation procedure.
