The keystone of H4D solutions is creating a pioneering technological tool: the H4D e-health booth. Booths follow the activities of doctors and paramedical personnel. They are monitoring tools for biometrical parameters, providing an aid in diagnosis and guidance. H4D e-health booths come in two modes: Teleconsultation, which allows a doctor to carry out a remote consultation, guided by the monitoring of vital parameters measured by the booth. Telemonitoring, which allows doctors, in a preventive setting or when following up on chronic illnesses, to track patients physiological parameters remotely and to act rapidly if necessary (emergency consultation, teleconsultation, phone call).
