High-Frequency, Low Tidal Volume Ventilation to Improve Catheter Stability During Atrial Fibrillation Ablation.

open access: yesJACC Clinical Electrophysiology, 2019
Atrial fibrillation (AF) recurrence after ablation often results from pulmonary vein reconnections caused by insufficient lesion formation [(1)][1].

Three‐dimensional geometric morphometric analysis of diaphragmatic dome motion in COPD patients

open access: yesThe Anatomical Record, EarlyView.
Abstract Diaphragmatic dysfunction is a hallmark of chronic obstructive pulmonary disease (COPD), especially in emphysema, where hyperinflation alters diaphragm geometry and impairs inspiratory mechanics. However, quantitative three‐dimensional (3D) assessments of diaphragmatic dome shape and motion across COPD phenotypes are limited.

Prospective Assessment of the Feasibility of a Trial of Low‐Tidal Volume Ventilation for Patients with Acute Respiratory Failure

open access: yesAnnals of the American Thoracic Society, 2018
Rationale: Low‐tidal volume ventilation (LTVV; 6 ml/kg) benefits patients with acute respiratory distress syndrome and may aid those with other causes of respiratory failure. Current early ventilation practices are poorly defined. Objectives: We observed

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

open access: yesAnnals 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 ...

Effects of oropharyngeal neuromuscular stimulation on the volumetric enlarged and reduced tongue base in minipigs

open access: yesThe Anatomical Record, EarlyView.
Abstract Hypoglossal nerve or tongue protruding muscle stimulation is a current treatment option for obstructive sleep apnea. Thus, the present study analyzed 3D deformations of the volumetric enlarged and reduced tongue base upon oropharyngeal neuromuscular stimulation.

Lung volume recruitment maneuvers and respiratory system mechanics in mechanically ventilated mice

open access: yes, 2009
The study aim was to establish how recruitment maneuvers (RMs) influence lung mechanics and to determine whether RMs produce lung injury. Healthy BALB/c mice were allocated to receive positive end-expiratory pressure (PEEP) at 2 or 6 cmH2O and volume ...

Evaluation of low tidal volume with positive end-expiratory pressure application effects on arterial blood gases during laparoscopic surgery [PDF]

open access: yes, 2020
Background: Pneumoperitoneum (PNP) and patient positions required for laparoscopy can induce pathophysiological changes that complicate anesthetic management during laparoscopic procedures.

Optimizing Strategies for Non‐Invasive Prospection of Settlements in the Intertidal Zone: A Case Study From the Centre of the Drowned Medieval Village of Tolsende (Scheldt Estuary, the Netherlands)

open access: yesArchaeological Prospection, EarlyView.
ABSTRACT Medieval and early modern drowned villages in the intertidal zone of the Scheldt estuary (the Netherlands) constitute intriguing yet largely understudied components of north‐western Europe's underwater cultural heritage. Despite their high archaeological potential as time capsules of past settlement landscapes, research has remained limited ...

Scanning Parametric Sediment Echosounder as Tool for Underwater Archaeological Prospection

open access: yesArchaeological Prospection, EarlyView.
ABSTRACT Underwater cultural heritage 3D prospection techniques, especially for remains that are partly buried in the ground, are only very rarely available and often can only be applied with considerable technical effort. To overcome this limitation, we evaluate a methodological adaption of widely used and available single channel parametric sediment ...

Hydrodynamic and sediment transport numerical modelling and applications at Tairua Estuary, New Zealand

open access: yes, 2014
Tairua Estuary is a partially mixed estuary located on the east coast of the Coromandel Peninsula, North Island, New Zealand. Like many estuaries worldwide, Tairua Estuary is experiencing rapid sedimentation, which is causing a range of environmental and
