COVENT-Tester: A low-cost, open source ventilator tester

HardwareX, 2021
COVENT-Tester (COVID-19 VENTilator Tester) is a low-cost and open source ventilator tester developed to calibrate the output of medical ventilators, including tidal volume, inspiratory pressure, and oxygen concentration. Currently, there are several open-

Mechanically Robust, Self‐Healable, and Cryotolerant GelMA Hydrogel for Wearable Tactile Sensors with Enhanced Durability, Lifetime, and Environmental Stability

Advanced Science, EarlyView.
A mechanically robust, self‐healable, moisturizing, cryotolerant and adhesive GelMA hydrogel is developed by incorporating polyvinyl alcohol, acrylic acid, sodium tetraborate, and glycerol into GelMA matrix via a photoinitiated polymerization process. The hydrogel‐derived omni‐healable ionotronic pressure sensor can sensitively and consistently monitor

Neonatal endotracheal flowmeter for tidal volume, airway pressure, and end-tidal gas

, 1985
We have designed a new endotracheal flowmeter to measure tidal volume, phasic and mean airway pressures, inspiratory time, and end-tidal PCO2 and PO2 in intubated infants. The flowmeter is light (11 g) and adds minimal dead space (1.0 ml) and resistance

Bio‐Inspired Internal Stress Engineering for Microscale Surface Cracking in Sensitive Strain Sensors

Advanced Science, EarlyView.
This study presents a bio‐inspired internal stress engineering strategy to fabricate highly sensitive crack‐based strain sensors. By harnessing the internal expansion energy of microspheres and the thickness‐dependent brittle‐to‐ductile transition of ultrathin gold films, tunable microscale cracks are generated.

Association between intraoperative tidal volume and postoperative acute kidney injury in non-cardiac surgical patients using a propensity score-weighted analysis

Scientific Reports
Acute kidney injury (AKI) is related to adverse clinical outcomes. Therefore, identifying patients at increased risk of postoperative AKI and proactively providing appropriate care is crucial.

Ventilation in acute respiratory distress syndrome: importance of low-tidal volume [PDF]

Annals of Translational Medicine, 2016
Acute respiratory distress syndrome (ARDS) is a lifethreatening syndrome that affects more than 150,000 patients annually in the United States with nearly 40–60% mortality (1-3). Over the past two decades, significant progress has been made in the fields of critical care, mechanical ventilation, fluid management and sedation practices that have ...

Electric Double Layer Engineering Induces O‐Down Interfacial Water Reorientation for Efficient and Long‐Term Seawater Electrolysis

Advanced Energy Materials, EarlyView.
The additive EDTMPS inhibits hydroxides deposition by chelating with Ca2+/Mg2+. It also disrupts the hydrogen bond network of interfacial water and expands the thickness of electric double layer, promoting more free water to flip into adsorbable O‐down configuration.

Low-Tidal-Volume Ventilation in the Acute Respiratory Distress Syndrome [PDF]

New England Journal of Medicine, 2007
A 55-year-old man who is 178 cm tall and weighs 95 kg is hospitalized with community-acquired pneumonia and progressively severe dyspnea. His arterial oxygen saturation while breathing 100% oxygen through a face mask is 76%; a chest radiograph shows diffuse alveolar infiltrates with air bronchograms. He is intubated and receives mechanical ventilation;
