Live Demonstration: Quasi-Digital Portable Pen to Monitor Anaesthetics Delivery

Sandro Carrara, Danilo Demarchi, Simone Aiassa, Francesco Grassi

The live demonstration presents the innovative concept of a portable pen-device able to sense anaesthetic compounds over time for improved anaesthesiology practice. A custom Printed Circuit Board (PCB) manage in the event-based quasi-digital domain the sam ...

IoT Bio-Electronic Multi-Panel Device for On-line Monitoring of Anaesthesia Delivery

Francesca Stradolini

After a failure of "One-Size-Fits-All" approach on traditional treatment of diseases, the age of multi-faceted personalized medicine came into being for tailoring therapy to get the best response in the highest safety margin. Personalized drug dosage is on ...

Raspberry-Pi based system for propofol monitoring

Sandro Carrara, Francesca Stradolini, Danilo Demarchi, Tugba Kilic, Abuduwaili Tuoheti

Induction of anesthesia with propofol is a largely adopted technique in hospital environments. The correct dosage of this compound is essential to avoid under- or over-anesthesia that may result in serious side-effects. Therefore, in clinical settings, lon ...

Energy metabolism in the rat cortex under thiopental anaesthesia measured

Rolf Gruetter, Nathalie Just, João Miguel das Neves Duarte, Sarah Catherine Sonnay

Barbiturates, commonly used as general anaesthetics, depress neuronal activity and thus cerebral metabolism. Moreover, they are likely to disrupt the metabolic support of astrocytes to neurons, as well as the uptake of nutrients from circulation. By employ ...

Xenon Recovery at Room Temperature using Metal-Organic Frameworks

Daniele Ongari

Xenon is known to be a very efficient anesthetic gas, but its cost prohibits the wider use in medical industry and other potential applications. It has been shown that Xe recovery and recycling from anesthetic gas mixtures can significantly reduce its cost ...

Electronic solutions for power system emulation

Guillaume Olivier Lanz

Nowadays electric power systems are subject to continuous changes and the needs in the power generation and delivery service are constantly increasing, with a higher complexity of a progressively more distributed network. Because the impact of a failure ca ...

Cascaded PID controller for anaesthesia delivery

Monia Guidi, Alena Simalatsar

The technologies for continuous measurement of the anaesthetic agents circulating in body fluids are not mature yet, though some preliminary prototypes exist already. We present a control algorithm that based on the real measurement of propofol plasma conc ...

Automatic Mallampati Classification Using Active Appearance Models

Jean-Philippe Thiran, Matteo Sorci, Anil Yuce, Gabriel Louis Cuendet

Difficult tracheal intubation assessment is an important research topic in anesthesia as failed intubations are important causes of mortality in anesthetic practice. The modified Mallampati score is widely used, alone or in conjunction with other criteria, ...
