USCOM1A Transducer

USCOM 1A uses advanced Doppler hemodynamics to monitor cardiac blood flow. Stroke Volume (SV) monitoring changes the way we manage fluid, inotropes, and vaso-actives, and how we diagnose and manage sepsis, heart failure and hypertension.

Fluid remains one of the most challenging clinical interventions and inappropriate administration has dire outcomes.

Sepsis is a medical emergency characterized by altered circulation, with death caused ultimately by circulatory failure.

Heart failure is the leading cause of death worldwide and early detection allows optimal management.

Hypertension damages the heart, vessels, brain and kidneys resulting in, at best, poor quality of life, while early detection and management of underlying hemodynamic derangements is crucial to improving therapy and outcomes.

USCOM 1A accurately measures blood flow, Stroke Volume and Cardiac Output, across the aortic or pulmonary valve. Regardless of whether the patient is in sinus rhythm, atrial fibrillation, on vasopressors, on and off ventilation or experiencing active autonomic regulatory changes such as in sepsis, USCOM 1A is reliable. This distinguishes USCOM 1A from blood pressure devices which display surrogates of flow derived from blood pressure measures.

USCOM 1A is improving management and saving lives in the neonatal, pediatric, critical care, emergency, perioperative, oncological, maternal and perinatal populations. Appropriate use of the USCOM 1A reduces mortality in septic shock patients.

Over 500 publications confirm the clinical utility of the USCOM 1A and demonstrate its outstanding reliability and reproducibility and role in clinical medicine - and it’s non-invasive.
