Noninvasive continuous cardiac output monitoring in perioperative and intensive care medicine.
The determination of blood flow, i.e. cardiac output, is an integral part of haemodynamic monitoring. This is a review on noninvasive continuous cardiac output monitoring in perioperative and intensive care medicine. We present the underlying principles and validation data of the following technologies: thoracic electrical bioimpedance, thoracic bioreactance, vascular unloading technique, pulse...
متن کاملDetermination of systemic vascular resistance by a noninvasive technic.
SUMMARY Measurement of systemic vascular resistance in man currently requires arterial and venous cannulation, so that cardiac output and mean arterial blood pressure may be simultaneously determined. This report describes a noninvasive technic for determining systemic vascular resistance (SVR.), utilizing an ultrasonic method for cardiac output measurement, and a combination of sphygmomanometr...

Aim and background : Hemodynamic monitoring of critical patients in intensive units is the cornstone of care. It constitutes an extensive part of care and is helpful in determination of the causes and the response to treatment of hemodynamic instability. Aim of this review articale is to investigate of the Non invasive hemodynamic monitoring in critical care units. Materials and Methods:61 art...
متن کاملNon-invasive cardiac output determination by two-dimensional independent Doppler during and after cardiac surgery.
PURPOSE This study was to compare noninvasive measurement of cardiac output (CO) using a novel Doppler technique with invasive CO measurements in the postcardiac surgical intensive care unit. DESCRIPTION Thirty-six patients (67.2 +/- 10 years, New York Heart Association functional class 3.1 +/- 0.3) undergoing coronary revascularization were prospectively examined postoperatively. One hundred...
متن کاملMeasuring cardiac changes using electrical impedance during delayed cord clamping: a feasibility trial
BACKGROUND To date no study has attempted to continuously evaluate changes in hemodynamics during delayed cord clamping in humans. We aimed to demonstrate 1. the feasibility of measurements of hemodynamics during delayed cord clamping and 2. to describe the changes that occur over each minute. RESULTS After vaginal delivery, term infants (37(0)-41(6) weeks) were placed on a Life Start® bed 10...
