Low Flow Liquid Calibration Setup [PDF]

Micromachines, 2015
This article describes a primary calibration setup, and its uncertainty, for low flow liquid calibrations at Bronkhorst High-Tech. It will be used to calibrate reference flow meters from 1 to 200 g/h.

Low flow anesthesia [PDF]

Serbian Journal of Anesthesia and Intensive Therapy, 2016
Historically, rebreathing anesthesia systems were invented to reduce the consumption of volatile anesthetics and to optimize respiratory gas conditioning. However, the industry is still modifying and optimizing the rebreathing circle systems. Most of the

Principle, Fabrication and Emerging Applications of Nanobottle Motor

Energies, 2022
Micro/nano-motors play an important role in energy, environment, and biomedicines. As a new type of nano-motors, nanobottles attract great attention due to their distinct advantages of a large cavity, high specific surface area, bionic streamline ...

Photoactive decontamination and reuse of face masks

e-Prime: Advances in Electrical Engineering, Electronics and Energy, 2023
The corona virus disease 2019 (COVID-19) pandemic has led to global shortages in disposable respirators. Increasing the recycling rate of masks is a direct, low-cost strategy to mitigate COVID-19 transmission.

Low‐flow anaesthesia [PDF]

Anaesthesia, 1995
Summary Although many anaesthesia machines are equipped with circle rebreathing systems, inhalational anaesthesia remains frequently performed using relatively high fresh‐gas flows. The major advantages of rebreathing techniques can be achieved only if the fresh‐gas flow is reduced to 1 l.min ...

Sigmoid isostiffness-lines: An in-vitro model for the assessment of aortic stenosis severity

Frontiers in Cardiovascular Medicine, 2022
IntroductionThe aortic valve opening area (AVA), used to quantify aortic stenosis severity, depends on the transvalvular flow rate (Q). The currently accepted clinical echocardiographic method assumes a linear relation between AVA and Q.

At what flow rate does the aortic valve gradient become severely elevated? Implications for guideline recommendations on aortic valve area cutoffs

Archives of Medical Science, 2021
Introduction Aortic stenosis (AS) is considered severe when the aortic valve area (AVA) is < 1.0 cm 2 and the mean aortic valve gradient (mAVG) exceeds 40 mm Hg.
