Deltex Medical Group plc is a United Kingdom-based haemodynamic management company, which manufactures fluid management devices. The Company's segments are Probes and Other. The Company's Esophageal Doppler Simulator (EDS) enables clinicians to practice probe insertion, focussing and waveform interpretation outside of a patient setting. The Company's CardioQ-EDM and CardioQ-EDM+ esophageal Doppler monitors (EDM) are designed to allow clinicians to guide fluid and drug administration during surgery. The Company's oesophageal Doppler haemodynamic monitoring (ODM) uses ultrasound to measure blood flows in the central circulation of patients, and allows doctors to fine tune the circulation. Its probes include surgical probes, such as I2S and I2P, and critical care probes, such as I2C and EDP240. Its I2S and I2P are used in patients who are anesthetized, sedated or awake. Its EDP240 is used in patients under anesthesia or full sedation. It has operations in Spain and Canada, among others.
