Deltex Medical Group PLC is a United Kingdom-based medical device company. The Company develops and manufactures specialist hemodynamics monitoring devices. The Company's TrueVue platform offers three monitoring technologies, such as TrueVue Doppler, TrueVue Impedance and TrueVue PressureWave. The TrueVue Doppler uses a single use disposable ultrasound probe which is placed into a sedated or anaesthetized patient’s esophagus via their nose or mouth. TrueVue Doppler provides a clinician with beat-to-beat real-time information on the patient’s circulating blood volume and heart function. TrueVue Impedance uses impedance cardiography to enable non-invasive continuous monitoring of awake patients. The TrueVue PressureWave uses the researched pulse pressure wave algorithm, which is available to derive haemodynamic parameters, calibrated from the Doppler. The Company offers its products to anesthetists working in the hospital’s operating room and intensivists working in critical care units.
