Standardized Unloading of Respiratory Muscles during Neurally Adjusted Ventilatory Assist: A Randomized Crossover Pilot Study.

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 in extremely low birth weight infants.

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-ventilator asynchrony.

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...

Non-Invasive Ventilation as an Adjunct to Exercise Training in Chronic Ventilatory Failure: A Narrative Review.

Chronic ventilatory failure (CVF) may be associated with reduced exercise capacity. Long-term non-invasive ventilation (NIV) may reduce patients' symptoms, improve health-related quality of life and reduce mortality and hospitalisations. There is an increasing use of NIV during exercise training with the purpose to train patients at intensity levels higher than allowed by their pathophysiological conditions.

Neurally adjusted ventilatory assist for children on veno-venous ECMO.

NAVA may improve veno-venous ECMO weaning in children. This is a retrospective small series, describing for the first time proof-of-principle for the use of NAVA in children on VV ECMO. Six patients (age 1-48 months) needed veno-venous ECMO. Controlled conventional ventilation was replaced with assisted ventilation as soon as lung compliance improved, and could trigger initiation and termination of ventilation. NAVA was then initiated when diaphragmatic electrical activity (EAdi) allowed for triggering. NA...

Post-extubation non-invasive ventilation in the pediatric intensive care unit: a multicenter study.

Extubation failure is a complication that increases morbidity and mortality. Noninvasive ventilation (NIV) has demonstrated to be effective as ventilatory support therapy.

Noninvasive ventilation for chronic hypercapnic respiratory failure.

Chronic hypercapnic respiratory failure is essentially a ventilatory failure. Noninvasive ventilation (NIV ) reduces the work of breathing, improves pulmonary compliance and alveolar ventilation, corrects gas exchange disorders and improves dyspnoea. However, treatment efficacy depends on the underlying pathology, on correct timing and on patient compliance. In this context, the principal role of the primary care physician is to search for, at every visit of at risk patients, signs and symptoms of ventilato...

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.

Evaluating the Cost-Effectiveness of Proportional-Assist Ventilation Plus vs. Pressure Support Ventilation in the Intensive Care Unit in Two Countries.

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...

Beyond the guidelines for non-invasive ventilation in acute respiratory failure: implications for practice.

Non-invasive ventilation is standard therapy in the management of both hypoxaemic and hypercapnic respiratory failure of various causes. The evidence base for its use and when and how it should be used has been reviewed in two recent guidelines. In this Series paper, we look beyond the guidelines to what is happening in everyday clinical practice in the real world, how patient selection can be refined to maximise the chances of a successful outcome, and emerging alternative therapies. Real-world application...

Benefits of non-invasive ventilation in acute hypercapnic respiratory failure.

Non-invasive ventilation (NIV) with bilevel positive airway pressure is a non-invasive technique, which refers to the provision of ventilatory support through the patient's upper airway using a mask or similar device. This technique is successful in correcting hypoventilation. It has become widely accepted as the standard treatment for patients with hypercapnic respiratory failure (HRF). Since the 1980s, NIV has been used in intensive care units and, after initial anecdotal reports and larger series, a numb...

Invasive Mechanical Ventilation.

Invasive mechanical ventilation is a potentially lifesaving intervention for acutely ill patients. The goal of this review is to provide a concise, clinically focused overview of basic invasive mechanical ventilation for the many clinicians who care for mechanically ventilated patients. Attention is given to how common ventilator modes differ in delivering a mechanical breath, evaluation of respiratory system mechanics, how to approach acute changes in airway pressure, and the diagnosis of auto-positive end...

Ventilation Parameters under Adaptive Servo Ventilation: A Comparison on Behalf of CSA-Pattern, BNP/NT-pro-BNP, and Ejection Fraction.

The SERVE-HF study has raised questions concerning the higher mortality under adaptive servoventilation. The ventilatory mode was discussed as a possible aggravating factor.

Effect of food intake on the ventilatory response to increasing core temperature during exercise.

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...

Ventilatory support after extubation in critically ill patients.

The periextubation period represents a crucial moment in the management of critically ill patients. Extubation failure, defined as the need for reintubation within 2-7 days after a planned extubation, is associated with prolonged mechanical ventilation, increased incidence of ventilator-associated pneumonia, longer intensive care unit and hospital stays, and increased mortality. Conventional oxygen therapy is commonly used after extubation. Additional methods of non-invasive respiratory support, such as non...

The effect of water immersion and acute hypercapnia on ventilatory sensitivity and cerebrovascular reactivity.

The partial pressure of end tidal carbon dioxide (PETCO ), ventilatory sensitivity to CO , and cerebral perfusion are augmented during thermoneutral head out water immersion (HOWI). We tested the hypotheses that HOWI and acute hypercapnia augments minute ventilation, ventilatory sensitivity to CO , cerebral perfusion, and cerebrovascular reactivity to CO . Twelve subjects (age: 24 ± 3 years, BMI: 25.3 ± 2.9 kg/m , 6 women) participated in two experimental visits: a HOWI visit (HOWI) and a matched hy...

Evolving Epidemiology of Home Mechanical Ventilation: A Rapidly Growing Challenge for Patient Care.

 Home mechanical ventilation is dramatically evolving in Germany. Patients with non-invasive and invasive ventilation are increasingly treated at home. In-hospital treatment of these patients is also necessary either for control visits or the management of acute medical problems. However, the development of in-hospital patient care, morbidity and mortality of these patients is unknown.

Assessing ventilatory threshold in individuals with motor-complete spinal cord injury.

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.

Minimally Invasive Left Ventricular Assist Device Implantation: Implementation Early in a Surgical Career.

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.

Effects of two different ventilation strategies on Respiratory mechanics during Robotic-gynecological surgery.

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 ...

Quantifying ventilatory control stability from spontaneous sigh responses during sleep: a comparison of two approaches.

Ventilatory control instability is an important factor contributing to the pathogenesis of periodic breathing (PB) and other forms of sleep-related breathing disorders (SRBD). The development of tools for the quantification of such instabilities from non-invasive respiratory measurements during sleep could be useful to clinicians in identifying subjects that are at risk of developing SRBD.

German National Guideline for Treating Chronic Respiratory Failure with Invasive and Non-Invasive Ventilation - Revised Edition 2017: Part 2.

Comparison of Noninvasive Dynamic Indices of Fluid Responsiveness Among Different Ventilation Modes in Dogs Recovering from Experimental Cardiac Surgery.

BACKGROUND Fluid resuscitation is a cornerstone of minimizing morbidity and mortality in critically ill patients, but the techniques for predicting fluid responsiveness is still a matter of debate. In this study, we aimed to evaluate the utility of noninvasive stroke volume variation (SVV), pulse pressure variation (PPV), and systolic pressure variation (SPV) as a dynamic predictor for assessing fluid responsiveness during different ventilation modes in anaesthetized, intubated dogs recovering from cardiac ...

The Injurious Effects of Elevated or Non-Elevated Respiratory Rate during Mechanical Ventilation.

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...
