Several manufacturers have developed systems that automatically measure the amount of blood in culture bottles. We compared volumes measured by Virtuo instrument (bioMérieux, France) (height-based volumes) and those calculated weighing In all, 150 pairs aerobic anaerobic bottles (BacT/ALERT FA/FN Plus, bioMérieux) were randomly selected over two periods to compare height- weight-based analyze e...

Monitoring of hemodynamic and mechanical parameters of the heart are reviewed. Clinical methodologies are discussed along with tools used in a research setting. Specifically, these include: arterial blood pressure, central venous pressure, pulmonary artery pressure, mixed venous oxygen saturation, cardiac output, pressure–volume loops, flow monitoring, and Frank–Starling curves. These parameter...

This paper outlines the development and hardware software integration of an instrumental setup designed towards the real-time assessment of the affective status of a computer user. This assessment is based on the measurement and digital signal analysis of three physiological variables that reflect dynamic changes of the Autonomic Nervous System (ANS): Blood Volume Pulse (BVP) measured with an i...

Apart from its complex functionality, the brain is a robust thermodynamic machine; the tissue metabolic rate is high and it is thermally shielded by a skull. Therefore, if there is no high-volume blood flow to cool and stabilize the brain temperature, the possibility of unstable behavior seems to be high. Inflowing arterial blood is normally cooler than the brain tissue temperature, and outflow...

immunosuppressants require therapeutic drug monitoring because of their narrow therapeutic index and significant inter-individual variability in blood concentrations. this variability can be because of factors like drug-nutrient interactions, drug-disease interactions, renal-insufficiency, inflammation and infection, gender, age, polymorphism and liver mass. drug monitoring is widely practiced ...
