PURPOSE: We conducted a systematic review and meta-analysis of randomized controlled trials (RCTs) to evaluate the effect of high-flow nasal cannula (HFNC) on reintubation in adult patients. PROCEDURES: Ovid Medline, Embase, and Cochrane Database of Systematic Reviews were searched up to November 1, 2016, for RCTs comparing HFNC versus conventional oxygen therapy (COT) or noninvasive ventilation (NIV) in adult patients after extubation. The primary outcome was reintubation rate, and the secondary outcomes included complications, tolerance and comfort, time to reintubation, length of stay, and mortality...

Continuous positive airway pressure (CPAP) has been used in infants with bronchiolitis for decades. Recently, high flow nasal cannula (HFNC) therapy was introduced We conducted a retrospective study of treatment with CPAP vs. HFNC between 2013 and 2015, comparing the development in respiratory rate, fraction of inspired oxygen (FiO2) and heart rate, treatment failure, duration of treatment, and length of hospital stay. A sample size of 49 children were included. Median age was 1.9 months. Median baseline pCO₂ was 7...

Tracheal intubation (TI) is a routine procedure in the Intensive Care Unit (ICU) and is often lifesaving. In contrast to the controlled conditions in the operating room, critically ill patients with respiratory failure and shock are physiologically unstable. These factors, along with under evaluation of the airway and suboptimal response to preoxygenation, are responsible for a high incidence of life-threatening complications such as severe hypoxemia and cardiovascular collapse during TI in the ICU. The All India Difficult Airway Association (AIDAA) proposes a stepwise plan for safe management of the airway in critically ill patients...

BACKGROUND: Non-invasive Neurally Adjusted Ventilator Assist (NIV-NAVA) was introduced to our clinical practice via a pilot and a randomized observational study to assess its safety, feasibility, and short term physiological effects. METHODS: The pilot protocol applied NIV-NAVA to 11 infants on nasal CPAP, high-flow nasal cannula (HFNC), or nasal IMV (NIMV), in multiple 2-4 h periods of NIV-NAVA for comparison. This provided the necessary data to design a randomized, controlled observational cross-over study in 8 additional infants to compare the physiological effects of NIV-NAVA to NIMV during 2-hour steady state conditions...

BACKGROUND: Transnasal Humidified Rapid-Insufflation Ventilatory Exchange has been shown to safely prolong the safe apnea time in well children post induction of anesthesia and is rapidly becoming a new standard for apneic oxygenation in adults. The same oxygenation technique is described as nasal high flow and can be used in infants and children at risk of apnea during anesthesia. AIM: We investigated the use of nasal high flow oxygen delivery during anesthesia in children with abnormal airways requiring tubeless airway assessment or surgery...

Recent calibrated fMRI techniques using combined hypercapnia and hyperoxia allow the mapping of resting cerebral metabolic rate of oxygen (CMRO2) in absolute units, oxygen extraction fraction (OEF) and calibration parameter M (maximum BOLD). The adoption of such technique necessitates knowledge about the precision and accuracy of the model-derived parameters. One of the factors that may impact the precision and accuracy is the level of oxygen provided during periods of hyperoxia (HO). A high level of oxygen may bring the BOLD responses closer to the maximum M value, and hence reduce the error associated with the M interpolation...

High flow nasal cannula (HFNC) oxygen therapy is a non-invasive form of respiratory support that is rapidly being taken up in paediatric intensive care units (PICU). For infants with bronchiolitis - who are the largest non-elective source of admissions to a PICU - there is some evidence that using HFNC therapy reduces the need for intubation and mechanical ventilation. The aim of this review article is is to explore, describe, critique and add to the evidence surrounding the use of HFNC therapy in the pediatric population for the management of respiratory distress...

High nasal flow (HNF) is a new method to deliver a high flow of oxygen (up to 60 l/min) through a nasal cannula. The inspiratory oxygen fraction can be set in a range from 21 to 100%. The inspired air is adjusted to body temperature and saturation. Many patients find it more comfortable than a conventional oxygen mask. In spite of these advantages, the mechanism of action is not completely understood and empirical evidence for its use is limited. This article provides a simplified explanation of variable positive airway pressure generation by HNF and related flushing of the anatomic dead space...

PURPOSE OF REVIEW: High-flow nasal cannula (HFNC) is emerging as a means of oxygen delivery and respiratory support for a range of conditions outside the perinatal period. We aim to review the mechanisms of action and advantages of HFNC and to summarize current findings regarding clinical benefit in specific pediatric disease processes and in patients with significant respiratory distress. RECENT FINDINGS: Currently published studies outside the neonatal population demonstrate both safety and efficacy of this mode of respiratory support...

OBJECTIVE: Nasal high-flow therapy (nHFT) is commonly used for noninvasive respiratory support in the neonatal intensive care unit. Our objective was to determine which aspects of neonatal nHFT have achieved adequate evidence base to support consensus among experienced clinical investigators, and to document areas lacking consensus to promote future investigations. STUDY DESIGN: Prospective, modified Delphi collation of tabular queries related to specific aspects of neonatal nHFT...

Objective. To investigate whether high-flow nasal cannula (HFNC) oxygen therapy is superior to conventional oxygen therapy for reducing hypoxemia and postoperative pulmonary complications (PPC) in patients with thoracoscopic lobectomy after extubation. Methods. Patients with intermediate to high risk for PPC were enrolled in this study. Subjects were randomly assigned to HFNC group (HFNCG) or conventional oxygen group (COG) following extubation. Arterial blood samples were collected after extubation at 1, 2, 6, 12, 24, 48, and 72 h...

Welders are more susceptible to pneumococcal pneumonia. The mechanisms are yet unclear. Pneumococci co-opt the platelet activating factor receptor (PAFR) to infect respiratory epithelial cells. We previously reported that exposure of respiratory cells to welding fumes (WF), upregulates PAFR-dependent pneumococcal infection. The signaling pathway for this response is unknown, however, in intestinal cells, hypoxia-inducible factor-1 α (HIF 1α) is reported to mediate PAFR-dependent infection. We sought to assess whether oxidative stress plays a role in susceptibility to pneumococcal infection via the platelet activating factor receptor...

BACKGROUND: Conflicting recommendations exist on whether high-flow nasal cannula (HFNC) oxygen therapy should be administered to adult patients in critical care with acute hypoxemic respiratory failure. We performed a meta-analysis of randomized controlled trials (RCTs) to evaluate its effect on intubation rates. METHODS: We searched electronic databases from inception to April 2016. We included RCTs that compared HFNC oxygen therapy with usual care (conventional oxygen therapy or noninvasive ventilation) in adults with acute hypoxemic respiratory failure...
