Based on theoretical modeling and optimization, we exploit the application of optical microfiber loop resonators in ambient refractive index sensing. We set up a reliable theoretical model and optimize the structural parameters of microfiber loop resonators including the radius of the microrfiber, the radius of the loop and the length of the coupling region(More)
Extracorporeal membrane oxygenation (ECMO) is increasingly being applied as life support for acute respiratory distress syndrome (ARDS) patients. However, the outcomes of this procedure have not yet been characterized in severe ARDS patients. The aim of this study was to evaluate the outcomes of severe ARDS patients supported with ECMO and to identify(More)
We demonstrate direct fabrication of homogeneous microfluidic channels embedded in fused silica by femtosecond laser direct writing, followed by wet chemical etching and glass drawing. In addition, the glass drawing process significantly reduces the inner surface roughness of the fabricated channels, and centimeter-level microfluidic channels with an aspect(More)
An intensive temperature sensor based on a liquid-core optical fiber has been demonstrated for the measuring the temperature of the environment. The core of fiber is filled with a mixture of toluene and chloroform in order to make the refractive index of the liquid-core and the cladding of the fiber close. The experiment shows that a temperature sensitivity(More)
OBJECTIVE To explore the effect of prone position ventilation (PPV) on respiratory mechanics and prognosis in patients with acute respiratory distress syndrome (ARDS) concurrent with interstitial lung disease (ILD). METHODS The data of 36 severe ARDS patients admitted to Department of Critical Care Medicine of the First Affiliated Hospital of Guangzhou(More)
OBJECTIVE To evaluate the effect of time elapsed on continuous pulse contour cardiac output (PCCO) measurement in septic shock patients. METHODS Data during February 2011 to February 2013 from 25 septic shock patients equipped with a pulse indicator continuous cardiac output (PiCCO) device in Department of Critical Care Medicine of Guangzhou Medical(More)
Stimulated Raman scattering of toluene and its mixture with chloroform is studied in liquid-core optical fiber. The results show a remarkably broadened Raman line of the mixture from about 630 nm to 650 nm by a pumping wavelength at 532 nm, which is assigned to the interaction of CH vibrations of the two liquids. The results suggest that interactions(More)
OBJECTIVE To investigate the value of N-terminal pro-B type natriuretic peptide (NT-proBNP) in predicting the outcome of spontaneous breathing trial (SBT) in ventilated elderly renal dysfunction patients. METHODS The clinical data of patients who received mechanical ventilation in the Department of Critical Care Medicine of the First Affiliated Hospital(More)
Electric fields are known to favor a ferroelectric phase with parallel electric dipoles over an antiferroelectric phase. We demonstrate in this Letter that electric fields can induce an antiferroelectric phase out of a ferroelectric phase in a NaNbO 3-based lead-free polycrystalline ceramic. Such an unlikely ferroelectric-to-antiferroelectric phase(More)
INTRODUCTION Prone position ventilation (PPV) has been shown to improve oxygenation and decrease pulmonary vascular resistance and mortality in patients with severe acute respiratory distress syndrome (ARDS). Whether these benefits of PPV occur similarly in acute exacerbations of interstitial lung disease (ILD) is not clear. We retrospectively explored the(More)
