Simplification of continuous intracoronary thermodilution [PDF]

EuroIntervention
Continuous intracoronary thermodilution with saline allows for the accurate measurement of volumetric blood flow (Q) and absolute microvascular resistance (Rμ). However, this requires repositioning of the temperature sensor by the operator to measure the entry temperature of the saline infusate, denoted as Ti.We evaluated whether Ti could be predicted ...

Dexmedetomidine infusions improve cardiovascular and renal function in anaesthetised, experimentally endotoxaemic horses

Equine Veterinary Journal, EarlyView.
Abstract Background Dexmedetomidine infusions are beneficial in anaesthetised endotoxaemic horses when administered concurrent to endotoxin, but post‐conditioning effects are unknown. Objectives To evaluate whether a dexmedetomidine infusion is beneficial in horses administered Escherichia coli O55:B5 lipopolysaccharides (LPS) endotoxin prior to ...

Cardiogenic Shock and Lung Injury as a Complication of Defibrillation

Journal of Pediatric Emergency and Intensive Care Medicine, 2017
Local burns, embolism, and arrhythmia are the most common side effects observed after electrical shock treatments. However, systolic function may be rarely affected and pulmonary edema may develop.

Agreement between invasive and oscillometric blood pressure measurements during controlled haemorrhage in anaesthetised horses

Equine Veterinary Journal, EarlyView.
Abstract Background Defining the reliability of oscillometry (NIBP) for measuring mean arterial pressure (MAP) during normotension and hypovolaemic hypotension could help with cardiovascular monitoring and management in horses anaesthetised in dorsal recumbency.

Derivation of Stroke Volume from Pulmonary Artery Pressures

Cardiology and Therapy
Introduction Intermittent cardiac output (CO) studies using thermodilution are considered the gold standard. We have developed a stroke volume (SV) calculator from pulmonary pulse pressure (PP) to allow continuous monitoring of SV and CO from PP. Methods
