WHAT THIS ARTICLE TELLS US THAT IS NEW: BACKGROUND:: Currently, there is no standardized method to set the support level in neurally adjusted ventilatory assist (NAVA). The primary aim was to explore the feasibility of titrating NAVA to specific diaphragm unloading targets, based on the neuroventilatory efficiency (NVE) index. The secondary outcome was to investigate the effect of reduced diaphragm unloading on distribution of lung ventilation.
Neurally adjusted ventilatory assist (NAVA) is expected to improve respiratory outcomes in preterm infants; however, it has not yet been evaluated. We investigated whether NAVA could improve respiratory outcomes and reduce sedation use in extremely low birth weight infants (ELBWIs).
Patient-v entilator asynchrony (PVA) is a mismatch between the patient, regarding time, flow, volume, or pressure demands of the patient respiratory system, and the ventilator, which supplies such demands, during mechanical ventilation (MV). It is a common phenomenon, with incidence rates ranging from 10% to 85%. PVA might be due to factors related to the patient, to the ventilator, or both. The most common PVA types are those related to triggering, such as ineffective effort, auto-triggering, and double tr...
Extubation failure is a complication that increases morbidity and mortality. Noninvasive ventilation (NIV) has demonstrated to be effective as ventilatory support therapy.
Although non-invasive forms of ventilation have recently spread in neonatology, invasive ventilation still plays a key role in the support of extremely low birth weight (ELBW) infants. The purpose of this study was to assess changes in neonatal ventilation practices for ELBW infants and compare outcomes between two epochs (2005-2009 vs. 2010-2015) to analyze progression stemming from the implementation of newer clinical guidelines.
Effect of Protocolized Weaning With Early Extubation to Noninvasive Ventilation vs Invasive Weaning on Time to Liberation From Mechanical Ventilation Among Patients With Respiratory Failure: The Breathe Randomized Clinical Trial.
In adults in whom weaning from invasive mechanical ventilation is difficult, noninvasive ventilation may facilitate early liberation, but there is uncertainty about its effectiveness in a general intensive care patient population.
Mechanical ventilation is an integral, but expensive, part of the intensive care unit (ICU). Optimal use of mechanical ventilation could save costs and improve patient outcomes. Here, the cost effectiveness of proportional assist ventilation (PAV™ ventilation by Medtronic) is estimated relative to pressure support ventilation (PSV). A cohort-level, clinical model was built using data from clinical trials. The model estimates patient-ventilator asynchrony >10%, tracheostomy, ventilator-associated pneumoni...
Patient-ventilator asynchrony may occur with modes of partial ventilatory support. Because this problem is associated with worsened outcomes, identifying and managing asynchronies has been recognized as a relevant clinical problem during both invasive and non-invasive (NIV) mechanical ventilation. Areas covered: In this review article, we first describe the different forms of patient-ventilator asynchrony and how they are classified and quantified. Then, we show how these asynchronies can be recognized, con...
The SERVE-HF study has raised questions concerning the higher mortality under adaptive servoventilation. The ventilatory mode was discussed as a possible aggravating factor.
Airway management and ventilation during a tracheobronchial stenting procedure are challenging given that mandatory positive pressure ventilation cannot be fully achieved while using a rigid bronchoscope due to leakage from the scope tip. Biphasic cuirass ventilation is a negative pressure ventilation method using an external cuirass fitted to the anterior chest, which could assist in spontaneous breathing and ventilation support. We report 3 successful anesthesia cases in which we could maintain adequate v...
Food intake increases metabolism and body temperature, which may in turn influence ventilatory responses. Our aim was to assess the effect of food intake on ventilatory sensitivity to rising core temperature during exercise. Nine healthy male subjects exercised on a cycle ergometer at 50% of peak oxygen uptake in sessions with and without prior food intake. Ventilatory sensitivity to rising core temperature was defined by the slopes of regression lines relating ventilatory parameters to core temperature. Me...
Introduction We evaluated post non-invasive ventilation survival and factors for the transition to tracheostomy in amyotrophic lateral sclerosis. Methods We analyzed 197 patients using a prospectively-collected database, with 114 patients since 2000. Results Of 114 patients, 59 patients underwent non-invasive ventilation (NIV), which prolonged the total median survival time to 43 months compared with 32 months without treatment. The best post-NIV survival was associated with a lack of bulbar symptoms, highe...

Investigate the acute effects of non-invasive ventilation (NIV) on cerebral blood flow (CBF) and on cognitive functions in COPD.
To assess the feasibility of measuring ventilatory threshold (VT) in higher-level, motor-complete spinal cord injury (SCI) using four different analysis methods based on non-invasive gas exchange.
Several centers have presented minimally invasive surgical approaches to centrifugal left ventricular assist device implantation. Although minimally invasive implantation has been successfully performed by experienced surgeons, at large implanting centers, it is unknown whether these techniques are widely adoptable. We evaluated the experience of a surgeon early in his career with conventional and minimally invasive approaches to device implantation.
It is unknown which is the best ventilatory approach in patients scheduled for gynecological robotic surgery in Deep Trendelenburg position in terms of respiratory mechanics. 40 patients were enrolled: 20 patients received a standard ventilation and 20 patients received a protective ventilation. Gas exchanges, respiratory mechanics and hemodynamic parameters were recorded. No significant differences were found between the two groups in terms of respiratory mechanics. In both groups, there was a significant ...
Today, invasive and non-invasive home mechanical ventilation have become a well-established treatment option. Consequently, in 2010, the German Respiratory Society (DGP) has leadingly published the guidelines on "Non-Invasive and Invasive Mechanical Ventilation for Treatment of Chronic Respiratory Failure." However, continuing technical evolutions, new scientific insights, and health care developments require an extensive revision of the guidelines. For this reason, the updated guidelines are now published....

Respiratory rate is one of the key variables we set and monitor during mechanical ventilation. As part of our increasing efforts to optimise mechanical ventilation, it is prudent that we expand our understanding of the potential harmful effects not only of volume and pressures, but also of respiratory rate. The mechanisms by which respiratory rate may become injurious during mechanical ventilation can be distinguished in two broad categories. In the first well-recognised category, concerning both controlled...
The hypoxic ventilatory response (HVR) is markedly attenuated by AMPK-α1 deletion conditional on the expression of Cre-recombinase in tyrosine hydroxylase (TH) expressing cells, precipitating marked increases in apnea frequency and duration. It was concluded that ventilatory dysfunction caused by AMPK deficiency was driven by neurogenic mechanisms. However, TH is transiently expressed in other cell types during development, and it is evident that central respiratory depression can also be triggered by myog...
The purpose of this study is to evaluate outcomes in MICU lung transplant recipients with acute respiratory failure treated with non-invasive positive pressure ventilation (NPPV) and identify factors associated with NPPV failure (need for intubation).
The effects of different ventilation strategies during CPR on patient outcomes and lung physiology are still poorly understood. This study compares positive pressure ventilation (IPPV) to passive oxygenation (CPAP) and a novel ultra-low tidal volume ventilation (ULTVV) regimen in an experimental ventricular fibrillation animal model.
Spirometry has been used as the main strategy for assessing ventilatory changes related to occupational exposure to particulate matter (OEPM). However, in some cases, as one of its limitations, it may not be sensitive enough to show abnormalities before extensive damage, as seen in restrictive lung diseases. Therefore, we hypothesized that cardiopulmonary exercise testing (CPET) may be better than spirometry to detect early ventilatory impairment caused by OEPM. We selected 135 male workers with at least on...
