Automated cardiac output measurements by ultrasound are inaccurate at high cardiac outputs [PDF]

Ultrasound in Obstetrics & Gynecology, 2000
AbstractObjectiveThe sonographic technique of automated cardiac output measurement (ACM) is a promising new method to measure cardiac output and could be of use in a high‐risk obstetric unit in the treatment of pre‐eclamptic patients. The aim was to determine the accuracy of the ACM method.DesignComparative study of the sonographic technique of ACM ...

Biologically‐Inspired Melt Electrowriting for the Generation of Highly Biomimetic Functional Myocardium

Advanced Functional Materials, EarlyView.
In this work, melt electrowriting is used to fabricate a 3D printed scaffold design that generates engineered cardiac tissues with in‐plane contraction, mimicking natural myocardium. It is shown that these tissues display advanced maturation and functionality.

Biointerfacing with AgBiS2 Quantum Dots for Pseudocapacitive Photostimulation

Advanced Functional Materials, EarlyView.
It is demonstrated that AgBiS2 quantum dots exhibit unique photoinduced pseudocapacitive charge transfer properties, enabling efficient light‐to‐electrical energy conversion. These quantum dots facilitate enhanced light absorption and transduction when integrated with ZnO nanowires, which serve as an effective charge transport medium.

Cardiac output measurement in children: comparison of Aesculon® cardiac output monitor and thermodilution [PDF]

British Journal of Anaesthesia, 2008
We compared cardiac output (CO) measurements by the non-invasive electrical velocimetry (Aesculon) monitor with the pulmonary artery catheter (PAC) thermodilution method in children.CO values using the Aesculon monitor and PAC thermodilution were simultaneously recorded during cardiac catheterization in children.

Narrowband Detection via Charge Collection Narrowing Organic Photodetector Enabled by Low Bandgap Random Terpolymer for Biometric Sensing

Advanced Functional Materials, EarlyView.
A novel low‐bandgap random terpolymer is designed for narrow band detection in charge collection narrowing (CCN) based organic photodetectors. With a relative thin active layer (<1 µm), the CCN‐based devices achieved a narrowband response of 68 nm full‐width‐at‐half‐maximum at 916 nm, together with Responsivity values of 0.13 A W−1 and dark current of ...
