BACKGROUND Many technologies have been developed for minimally invasive monitoring of cardiac output. Estimated continuous cardiac output (esCCO) measurement using pulse wave transit time is one noninvasive method. Because it does not require any additional sensors other than those for conducting 3 basic forms of monitoring (electrocardiogram, pulse(More)
A new non-invasive continuous cardiac output (esCCO) monitoring system solely utilizing a routine cardiovascular monitor was developed, even though a reference cardiac output (CO) is consistently required. Subsequently, a non-invasive patient information CO calibration together with a new automated exclusion algorithm was implemented in the esCCO system. We(More)
BACKGROUND Postoperative atrial fibrillation in coronary artery bypass graft surgery occurs in 10-40% of patients. It is associated with a significant degree of morbidity and results in prolonged lengths of stay in both the intensive care unit and hospital. METHODS The authors prospectively evaluated patients undergoing coronary artery bypass with(More)
This study investigated the accuracy of the NICO monitor equipped with the newer software. Additionally, the effects of the increased dead space produced by the NICO monitor on ventilatory settings were investi- gated. Forty-two patients undergoing elective aortic reconstruction participated in this prospective, obser- vational study at a university(More)
Atrial natriuretic peptide (ANP) has been known to be protective against hepatic ischemia/reperfusion injury. The purpose of this study was to verify the hypothesis that ANP conserves microvascular circulation and reduces ischemia–reperfusion injury in the in vivo rabbit model. With IRB approval, 30 male Japanese white rabbits under pentobarbital anesthesia(More)
BACKGROUND We hypothesized that mixed venous hemoglobin oxygen saturation (SvO2) can be estimated by calculation from CO2 production, cardiac output, and arterial oxygen saturation measured using a noninvasive cardiac output (NICO) monitor (Novametrix-Respironics, Wallingford, CT). METHODS Twenty-three patients undergoing aortic aneurysm repair underwent(More)
t n S r p a w p s HE MOST COMMONLY used method of cardiac output (CO) monitoring during anesthesia and intensive care is ontinuous thermodilution with a pulmonary artery catheter PAC), although several concerns have been raised about its sage because of the lack of a clear clinical advantage. Reently, less invasive CO monitoring devices have been introuced(More)
BACKGROUND esCCO (estimated continuous cardiac output, Nihon Kohden, esCCO) is a new cardiac output measurement system which uses pulse wave transit time to calculate cardiac output continuously and non-invasively. One of the most commonly used methods to monitor cardiac output is continuous cardiac output CCO (Edwards Lifesciences) which has an accuracy(More)
BACKGROUND The purpose of this study was to determine the effects of transient arterial blood pressure change on the accuracy of the FloTrac™/Vigileo™ monitor (Edwards Lifesciences, Irvine, CA). METHODS We compared stroke volume determined with the FloTrac/Vigileo with Doppler during anesthetic induction in 20 patients undergoing abdominal aortic(More)
