BACKGROUND Cardiac Index (CI) is a key-parameter of hemodynamic monitoring. Indicator-dilution is considered as gold standard and can be obtained by pulmonary arterial catheter or transpulmonary thermodilution (TPTD; CItd). Furthermore, CI can be estimated by Pulse-Contour-Analysis (PCA) using arterial wave-form analysis (CIpc). Obviously, adjustment of CIpc to CItd initially improves the accur...

Digital innovations are changing medicine, and hemodynamic monitoring will not be an exception. Five to ten years from now, we can envision a world where clinicians will learn hemodynamics with simulators and serious games, will monitor patients with wearable or implantable sensors in the hospital and after discharge, will use medical devices able to communicate and integrate the historical, cl...

The incidence of intraoperative arrhythmia is extremely high, and some arrhythmias require clinical attention. Therefore, it is essential for the anesthesiologist to evaluate risk factors for arrhythmia and understand their etiology, electrophysiology, diagnosis, and treatment. Anesthetic agents reportedly affect normal cardiac electrical activity. In the normal cardiac cycle, the sinoatrial no...

Like adults, children taking beta-blockers are at risk for serious hemodynamic instability in case of anaphylaxis. We report a case of severe bradycardia associated with anaphylactic shock after aprotinin in a beta-blocked child, which was resistant to intravenous epinephrine and vascular filling but was treated successfully with isoproterenol.

conclusions music therapy is a safe, simple, inexpensive, and non-invasive nursing intervention, which can significantly alleviate patients’ anxiety during coronary angioplasty. patients and methods this was a randomized controlled trial, conducted in the catheterization laboratory unit of baqiyatallah hospital, in tehran, iran. a sample of 64 patients, who were planned to undergo coronary angi...

Communications to the Editor accurate and reproducible. We cannot explain the discrepant hemodynamic measurements obtained in the one patient reported in the present letter which contradicts our findings, except to say that hemodynamic measurements may lag behind changes in the respiratory cycle during CSB. \% do agree with the author that further evaluation ofthe precise hemodynamic changes as...

Effect of Combinational Changes Catheter Size and its Negative Suction Pressure on Hemodynamic Parameters Mechanical Ventilation Patients

INTRODUCTION Thoracic surgery frequently requires one-lung ventilation (OLV). Hemodynamic changes are significant during OLV and surgical manipulation and precise management of fluid administration is vital to postoperative recovery and surgical outcome. The FloTrac system, a minimally invasive hemodynamic monitoring device, with continuous cardiac output (CO) and stroke volume variation (SVV) ...

Neurovascular coupling refers to the relationship between neuronal activities and downstream hemodynamic responses. Photoacoustic tomography (PAT), enabling comprehensive label-free imaging of hemodynamic activities with highly scalable penetration and spatial resolution, has great potential in the study of neurovascular coupling. In this review, we first introduce the technical basis of hemody...
