PhysioFlow® (PF®) is a new cardiac output (CO) monitoring method by impedance cardiography
(IC), never studied in pediatric intensive care unit (PICU). The aim of the study was to
compare CO and cardiac index (CI) measurements (IC) by trans-thoracic Doppler
echocardiography (TTE) (COTTE and CITTE) and PF® (COIC and CIIC) in PICU.
