BACKGROUND: During synchronised mechanical ventilation, positive airway pressure and spontaneous inspiration coincide. If synchronous ventilation is provoked, adequate gas exchange should be achieved at lower peak airway pressures, potentially reducing baro/volutrauma, air leak and bronchopulmonary dysplasia. Synchronous ventilation can potentially be achieved by manipulation of rate and inspiratory time during conventional ventilation and employment of patient-triggered ventilation. OBJECTIVES: To compare the efficacy of:(i) synchronised mechanical ventilation, delivered as high-frequency positive pressure ventilation (HFPPV) or patient-triggered ventilation (assist control ventilation (ACV) and synchronous intermittent mandatory ventilation (SIMV)), with conventional ventilation or high-frequency oscillation (HFO);(ii) different types of triggered ventilation (ACV, SIMV, pressure-regulated volume control ventilation (PRVCV), SIMV with pressure support (PS) and pressure support ventilation (PSV))...

BACKGROUND: Continuous high-frequency oscillation (CHFO) creates a pressure gradient in the small airways that accelerates expiratory flow. The intended use of CHFO therapy is to facilitate secretion removal and treat atelectasis. Our objective was to assess the feasibility, safety, and efficacy of CHFO in the mechanically ventilated pediatric population. METHODS: After institutional review board approval, we retrospectively reviewed medical records of mechanically ventilated children treated with CHFO (the MetaNeb system) at our institution from July 1, 2007 through August 31, 2012...

Non-invasive high-frequency oscillatory ventilation (NHFOV) consists of the application of a bias flow generating a continuous distending positive pressure with superimposed oscillations, which have constant frequency and active expiratory phase. NHFOV matches together the advantages of high-frequency ventilation (no need for synchronisation, high efficacy in removing CO2) and nasal continuous positive airway pressure (CPAP) (non-invasive interface, increase in functional residual capacity allowing oxygenation to improve)...

BACKGROUND: Congenital diaphragmatic hernia is a severe congenital anomaly with significant mortality and morbidity, for instance chronic lung disease. Sphingolipids have shown to be involved in lung injury, but their role in the pathophysiology of chronic lung disease has not been explored. We hypothesized that sphingolipid profiles in tracheal aspirates could play a role in predicting the mortality/ development of chronic lung disease in congenital diaphragmatic hernia patients. Furthermore, we hypothesized that sphingolipid profiles differ between ventilation modes; conventional mechanical ventilation versus high-frequency oscillation...

OBJECTIVE: Accurate and validated predictors of outcome for infants with congenital diaphragmatic hernia are needed. Score for Neonatal Acute Physiology-II has been validated to predict mortality in newborns. We investigated whether Score for Neonatal Acute Physiology-II scores in congenital diaphragmatic hernia could predict mortality, need for extracorporeal membrane oxygenation (in patients born in a center with extracorporeal membrane oxygenation availability), and development of bronchopulmonary dysplasia (oxygen dependency beyond 28 d after birth) in survivors...

UNLABELLED: Purpose/Aim : High-frequency oscillatory ventilation (HFOV) is a method of ventilation that theoretically achieves the goals of lung protective ventilation in acute respiratory distress syndrome (ARDS) patients. It is characterized by a rapid delivery of small tidal volumes at high frequencies oscillating around a continuous distending pressure (CDP). Optimization of CDP is not an easy task and it is titrated empirically in the clinical practice. The aim of this study is to investigate whether the level of CDP consistently affects the shape of the partial pressure of oxygen (PaO2) response to stepwise changes in CDP during HFOV of healthy and ARDS-induced pigs...

BACKGROUND: High-frequency oscillation (HFO) is an alternative to conventional mechanical ventilation that is sometimes used to treat people with acute respiratory distress syndrome, but effects on oxygenation, mortality and adverse clinical outcomes are uncertain. This review was originally published in 2004 and was updated in 2013 and again in 2015. OBJECTIVES: To determine the effects of HFO compared to conventional mechanical ventilation on physiological outcomes, clinical outcomes, and mortality when used for the treatment of acute respiratory distress syndrome (ARDS)...

BACKGROUND: The progressive and chronic course of COPD, characterized by difficulty in breathing, can be aggravated by periods of increased symptoms (exacerbation). The treatment often involves in-hospital care and among the interventions applied in COPD patients, physical therapy prompts good results. However the most used techniques are not properly pinpointed and there is no consensus in the literature regarding its effectiveness. METHODS: A systematic review was performed to identify which physical therapy treatment was applied in these cases...

BACKGROUND: The management of congenital diaphragmatic hernia (CDH) in neonates has evolved considerably over the last three decades. Initial stabilization followed by surgical repair is the current standard of care. A subset fails to achieve adequate oxygenation with medical management, including the use of high frequency oscillation and inhaled nitric oxide. The mortality in this group exceeds 80% without additional management strategies. Extracorporeal life support (ECLS) is a well-established modality for managing these neonates with CDH and has been shown to improve early survival in selected cases...

UNLABELLED: The predicitive values of fetal ultrasonography and magnetic resonance imaging are well established as antenatal outcome predictors in neonates with congenital diaphragmatic hernia (CHD). Postnatal outcome predictors remain elusive. THE AIM: To evaluate the value of the oxygenation index (OI) as a predictor of postnatal survival. MATERIAL AND METHODS: 58 newborns with congenital diaphragmatic hernia, treated in the same centre (a university hospital) between February 2006 and March 2014 were involved in the retrospective study...

After the High Frequency Oscillatory Ventilation (HFOV) has been applied in the invasive ventilator, the new technique of noninvasive High Frequency Oscillatory Ventilation (nHFOV) which does not require opening the patient's airway has attracted much attention from the field. This paper proposes the design of an experimental positive pressure-controlled nHFOV ventilator which utilizes a blower and a special valve and has three ventilation modes: spontaneous controlled ventilation combining HFOV, time-cycled ventilation combining HFOV (T-HFOV), and continuous positive airway pressure ventilation combining HFOV...

OBJECTIVE: Noninvasive high frequency oscillatory ventilation (NHFOV) has not been studied beyond neonatal age and with interfaces other than nasal prongs. We set up a preliminary study to investigate feasibility, oscillation transmission, and volume delivery of face mask-delivered NHFOV in a bench model mimicking a normal 1-year infant without any lung disease and then in vivo in a series of infants with same characteristics. DESIGN: A mannequin with upper airways was connected to an electronic active lung simulator ventilated through NHFOV with varying parameters...

Several promising therapies assessed in the adult critically ill in large, multicenter randomized controlled trials (RCTs) were associated with significantly increased mortality in the intervention arms. Our hypothesis was that there would be wide ranges in sponsorship (industry or not), type(s) of intervention(s), use of DSMBs, presence of interim analyses and early stopping rules, absolute risk increase (ARI), and whether or not adequate prior proof-of-principle Phase II studies were done of RCTs that found increased mortality rates of the intervention compared to control groups...

Pauline K Park
Severe hypoxemia is associated with untoward outcomes in acute respiratory distress syndrome patients. Nevertheless, in and of itself, correction of hypoxemia is not an adequate surrogate outcome for mortality and clear evidence-based targets for correction of hypoxemia remain to be determined. At present, clinical management is directed toward achieving sufficient oxygenation while minimizing toxicity of ventilator-induced lung injury. The gold standard remains lung-protective mechanical ventilation, using lower-tidal volumes and pressure-limited ventilator titration...
