Comparison studies comparing hemodynamic parameters provided by the Caretaker against respective Gold Standard references.
Invasive pulmonary capillary wedge pressure measurements using a Swan-Ganz catheter (SGC) is considered the gold standard for cardiac output (CO) monitoring. In this prospective study, we will compare CO measurements between a PPG-based wearable monitor and a SGC in ambulatory CHF patients.
Mixed venous saturation (SvO2) is an indicator of the balance between oxygen supply and demand in the body's tissues Recently, our research team published a paper describing the possibility to continuously monitor SvO2 by the use of continuous dynamic capnography (Karlsson et al, A Continuous Noninvasive Method to Assess Mixed Venous Oxygen Saturation: A Proof-of-Concept Study in Pigs. Anesth Analg 2020) The primary objective of the current study is thus to investigate the agreement and trending ability for capnodynamically derived SvO2 against the gold standard CO-oximetry. The secondary objective is to investigate the agreement and trending ability for capnodynamically derived CO (COEPBF) against the modified CO2-Fick method.
The present study aims at assessing the ability of a new pulse contour device for diagnosing a >15% stroke volume (SV) increase during patient hemodynamic optimization by fluid challenge in high risk abdominal surgery.
The Swan-Ganz catheter is the gold standard to measure cardiac output during liver transplantation surgery. This is an invasive hemodynamic monitoring system. The VenArt Cardiac Output (Mespere LifeSciences, Waterloo, Canada) is a new, innovative and non-invasive device that permits hemodynamic monitoring. With a software based on Fick's principle it is able to calculate cardiac output, cardiac index and continuous cardiac output. The hypothesis of this study is to investigate the precision and accuracy of this method versus the standard of care during liver transplantation.
Study to assess the feasibility of real-time automatic cardiac output measurements using transthoracic echocardiography (TTE)
The purpose of the research is to characterize the effect of labetalol, atenolol, and nifedipine on maternal hemodynamics early in pregnancy. Patients will be given medication based on their hemodynamics and asked to return for a repeat measurement.
This study will evaluate whether supplementation of exogenous ketones in patients with severe left ventricular dysfunction and acutely decompensated heart failure requiring inotropic therapy would improve the patient's hemodynamics and symptoms.
Cardiac surgery is at high risk of low cardiac output syndrome after procedure. Monitoring cardiac function, and especially cardiac output, is important to identify cardiovascular dysfunction and to introduce and adjust optimal therapies. Invasive monitor such as pulmonary arterial catheter or transpulmonary thermodilution provide precise measurements but need an invasive access to arterial and central venous route, with possible complications. Cardiographic bioimpedencemetry (Niccomo device, Imedex Corp) allows a non invasive measurement of cardiac output and some other parameters of cardiovascular function. Nevertheless, the reliability of this device has been little studied after cardiac surgery.
