Cerium dioxide (CeO2) was pretreated with reduction and reoxidation under different conditions in order to elucidate the role of surface Ce4+ oxygen vacancies catalytic activity for direct synthesis dimethyl carbonate (DMC) from CO2 methanol. The corresponding catalysts were comprehensively characterized using N2 physisorption, XRD, TEM, XPS, TPD, CO2-FTIR. results indicated that treatment promotes conversion Ce3+ improves concentration vacancies, while facilitates decreases vacancies....
The successful implementation of assisted ventilation depends on matching the patient's effort with ventilator support. Pressure muscle index (PMI), an airway pressure based measurement, has been used as noninvasive monitoring to assess inspiratory effort. authors aimed evaluate feasibility support adjustment according PMI target and diagnostic performance predict contribution during
Objectives The purpose of this study was to evaluate the predictive value cough peak flow (CPF) for successful extubation in postcraniotomy critically ill patients. Design This a single-centre prospective diagnostic study. Setting conducted three intensive care units (ICUs) teaching hospital. Participants Postcraniotomy patients who were 18 years or older, stayed ICU more than 24 hours and underwent mechanical ventilation eligible Patients excluded if one following present: no attempt during...
BACKGROUND: Excessively deep sedation is prevalent in mechanically ventilated patients and often considered suboptimal. We hypothesized that the bispectral index (BIS), a quantified electroencephalogram instrument, would accurately detect levels of sedation. METHODS: prospectively enrolled 90 critically ill who were receiving The BIS was monitored for 24 hours compared with Richmond Agitation Sedation Scale (RASS) evaluated every 4 hours. Deep defined as RASS −3 to −5. Threshold values...
Abstract The pandemic of Coronavirus Disease 2019 (COVID-19) is causing enormous loss life globally. Prompt case identification critical. reference method the real-time reverse transcription PCR (RT-PCR) assay, whose limitations may curb its prompt large-scale application. COVID-19 manifests with chest computed tomography (CT) abnormalities, some even before onset symptoms. We tested hypothesis that application deep learning (DL) to 3D CT images could help identify infections. Using data...

There is no widely accepted consensus on the weaning and extubating protocols for neurosurgical patients, leading to heterogeneity in clinical practices high rates of delayed extubation failure-related health complications.
Patient-ventilator asynchrony is common in mechanically ventilated patients and may be related to adverse outcomes. Few studies have reported the occurrence of brain-injured patients. We aimed investigate prevalence, type severity patient-ventilator with brain injury. This prospective observational study enrolled acute undergoing mechanical ventilation. Esophageal pressure monitoring was established after enrollment. Flow, airway pressure, esophageal pressure-time waveforms were recorded for...
Assessment of the patient's respiratory effort is essential during assisted ventilation. We aimed to evaluate accuracy airway pressure (Paw)-based indices detect potential injurious inspiratory support (PS) ventilation.In this prospective diagnostic study conducted in four ICUs two academic hospitals, 28 adult acute failure patients undergoing PS ventilation were enrolled. A downward titration was from 20 cmH2O 2 at a interval. By performing an end-expiratory occlusion maneuver, negative Paw...
Bedside assessment of low levels inspiratory effort, which are probably insufficient to prevent muscle atrophy, is challenging. The flow index, derived from the analysis portion flow-time waveform, has been recently introduced as a non-invasive parameter evaluate effort. primary objective present study was provide an external validation index detect effort.Datasets containing flow, airway pressure, and esophageal pressure (Pes)-time waveforms were obtained previously published in 100 acute...
Esophageal pressure, used as a surrogate for pleural is commonly measured by air-filled balloon, and the accuracy of measurement depends on proper balloon volume. It has been found that larger filling volume required at higher surrounding pressure. In present study, we determined pressure-volume relationship in bench model simulating cavity during controlled ventilation. The aim was to confirm whether an optimal range existed could provide accurate both end-expiration end-inspiration.We...
Accurate measurement of esophageal pressure (Pes) depends on proper filling the balloon. Esophageal wall elastance (Ees) may also influence measurement. We examined estimation balloon-surrounding in a bench model and investigated simplified calibrating procedure Pes balloon with relatively small volume. The Cooper catheter (geometric volume 2.8 ml) was used present study. progressively inflated different gas-tight glass chambers inner volumes. Chamber measured by fitting chamber Balloon...

Postoperative agitation frequently occurs after general anesthesia and may be associated with serious consequences. However, studies in neurosurgical patients have been inadequate. We aimed to investigate the incidence risk factors for early postoperative craniotomy, specifically focusing on association between pneumocephalus agitation. Adult intensive care unit admitted elective craniotomy under were consecutively enrolled. Patients assessed using Sedation-Agitation Scale during first 24...
Abstract The standard high-flow tracheal (HFT) interface was modified by adding a 5-cm H 2 O/L/s resistor to the expiratory port. First, in test lung simulating spontaneous breathing, we found that HFT caused an elevation airway pressure as power function of flow. Then, three oxygen treatments (T-piece at 10 L/min, and 40 L/min) were delivered random crossover fashion six tracheostomized pigs before after induction injury. induced significantly higher compared with either T-piece or ( p <...

Introduction There are concerns that the use of positive end-expiratory pressure (PEEP) in patients with brain injury may potentially elevate intracranial (ICP). However, transmission PEEP into thoracic cavity depends on properties lungs and chest wall. When wall elastance is high, can significantly increase pleural pressure. In present study, we investigate different effects ICP respiratory mechanics. Methods analysis This study a prospective, single-centre, physiological severe injury....
