Evaluation of a noninvasive continuous cardiac output monitoring system based on thoracic bioreactance.
Noninvasive cardiac output (CO) measurement can be useful in many clinical settings where invasive monitoring is not desired. Bioimpedance (intrabeat measurement of changes in transthoracic voltage amplitude in response to an injected high-frequency current) has been explored for this purpose but is limited in some clinical settings because of inherently low signal-to-noise ratio. Since changes...
متن کاملNoninvasive monitoring cardiac output using partial CO(2) rebreathing.
This article reviews use of partial carbon dioxide rebreathing devices to determine cardiac output and their application for hemodynamic monitoring in the ICU and operating room. The primary focus is on the NICO monitoring device. Compared with conventional cardiac output methods, these techniques are noninvasive, easily automated, and provide real-time and continuous cardiac output monitoring....
متن کاملComparative study of noninvasive cerebrovascular monitoring methods in cardiac surgery.
Unfavorable incidents during cardiac operations due to inadequate cerebral perfusion can be avoided by the utilization of noninvasive blood flow monitoring methods. The purpose of this study was to evaluate monitoring systems for cebrovascular perfusion. We compared currently available blood flow monitoring devices including transcranial Doppler (TCD), central retinal artery color Doppler (CRAD...
متن کاملNoninvasive cardiac output and blood pressure monitoring cannot replace an invasive monitoring system in critically ill patients
BACKGROUND Monitoring of cardiac output and blood pressure are standard procedures in critical care medicine. Traditionally, invasive techniques like pulmonary artery catheter (PAC) and arterial catheters are widely used. Invasiveness bears many risks of deleterious complications. Therefore, a noninvasive reliable cardiac output (CO) and blood pressure monitoring system could improve the safety...
متن کاملA System for Continuous Estimating and Monitoring Cardiac Output via Arterial Waveform Analysis
Background: Cardiac output (CO) is the total volume of blood pumped by the heart per minute and is a function of heart rate and stroke volume. CO is one of the most important parameters for monitoring cardiac function, estimating global oxygen delivery and understanding the causes of high blood pressure. Hence, measuring CO has always been a matter of interest to researchers and clinicians. Sev...
