Evaluation of oesophageal pulse oximetry in patients undergoing cardiothoracic surgery [PDF]

, 2003
Pulse oximetry probes placed peripherally may fail to give accurate values of blood oxygen saturation when the peripheral circulation is poor. Because central blood flow may be preferentially preserved, we investigated the oesophagus as an alternative ...

Optimized Strategy for Fabricating High‐Aspect‐Ratio Periodic Structures Over Large Areas Using ps‐Direct Laser Interference Patterning

Advanced Engineering Materials, EarlyView.
Picosecond direct laser interference patterning (DLIP) enables precise microstructure fabrication on stainless steel. Using a multiscan approach, high‐aspect‐ratio patterns are achieved. Fluence influences structure growth and homogeneity, with smaller periods yielding better uniformity.

Normal jugular bulb oxygen saturation [PDF]

Journal of Neurology, Neurosurgery & Psychiatry, 2003
Normal values of the jugular bulb oxygen saturation were obtained in 1942 and in 1963. Correct catheter positioning was not confirmed radiologically.To replicate the measurements during angiographic catheterisation of the jugular bulb.Oxygen saturation in the jugular bulb (SjO(2)), inferior petrosal sinus (SipsO(2)), and internal jugular vein was ...

Ag Cluster‐Modified K0.5Na0.5NbO3 Piezocatalyst for Enhanced Electrochemical Dinitrogen Reduction Reaction

Advanced Engineering Materials, EarlyView.
Ag cluster‐modified K0.5Na0.5NbO3 acts as an efficient piezocatalyst for electrochemical N2 reduction, enhanced by built‐in electric fields under mechanical actuation. Comparative studies between static and actuated electrodes reveal improved performance under dynamic conditions.

Influence of acute haemodynamic changes on the oxygen saturation during electro-convulsive therapy

Journal of Neuroanaesthesiology and Critical Care, 2014
Background: Electro-convulsive therapy (ECT) is a safe and effective treatment for various psychiatric disorders. Among the various complications associated with ECT, acute haemodynamic responses and decrease in the oxygen saturation are the most common.

Surface Modification of Sol–Gel Synthesized Ba0.85Ca0.15Zr0.1Ti0.9O3 using Stearic Acid Additives

Advanced Engineering Materials, EarlyView.
This study explores a novel approach to enhance the piezoelectric performance of lead‐free BCZT ceramics synthesized via the sol–gel method. By coating the BCZT powder with only a 0.69 nm stearic acid layer, the electromechanical response is significantly boosted up to 359 pC N−1, revealing promising implications for high‐performance sensor and ...
