The British company, Deltex Medical Group PLC, is a global leader in haemodynamic monitoring technology, with its primary technology being a Doppler-based ultrasound oesophageal haemodynamic monitoring system marketed as TrueVue Doppler. This system generates real-time data on descending aortic blood flow velocity on anesthetized or sedated patients, providing accurate information to guide anaesthetists on administration of fluid and drugs in surgical patients. Deltex Medical's ODM system is supported by clinical evidence from peer-reviewed trials, which has shown that it helps clinicians deliver improved surgical outcomes, fewer complications, and shorter patient stays in the hospital. The company has recently added new functionality to its ODM platform, called TrueVue, which combines High Definition Impedance Cardiography (HD-ICG), Pulse Pressure Waveform Analysis (PPWA), and Velocity/Pressure (VP) Loops software to make haemodynamic monitoring standard of care.
