RecruitingDevice studyNon-invasive Central Venous Pressure Estimation in Pediatric PatientsCentral Venous Pressure (CVP) is a standard parameter for hemodynamic monitoring and is currently measured through the insertion of a catheter. The pediatric population is especially vulnerable to risks associated to this invasive procedure, including infection, thrombosis, and pneumothorax. The proposed pilot study will evaluate safety and preliminary efficacy of a new non-invasive ultrasound-based venous occlusion pressure (VOP) monitoring device (CPMX2) in children equipped with an invasive catheter for CVP monitoring as part of standard of care.
