High flow nasal cannula oxygenation has distinct advantages over other oxygen devices due to its unique effects on respiratory physiology. In particular, adjustable oxygen delivery and flow-dependent carbon dioxide clearance from the upper airway reduce work of breathing and can better match inspiratory demand during respiratory distress. Historically, few studies had evaluated whether the physiologic effects of these devices translated into clinical benefit. However, recent publications have begun to address this knowledge gap...

OBJECTIVES: In patients with acute hypoxemic respiratory failure, noninvasive ventilation and high-flow nasal cannula oxygen are alternative strategies to conventional oxygen therapy. Endotracheal intubation is frequently needed in these patients with a risk of delay, and early predictors of failure may help clinicians to decide early. We aimed to identify factors associated with intubation in patients with acute hypoxemic respiratory failure treated with different noninvasive oxygenation techniques...

INTRODUCTION: Several reports have described the usefulness of a high-flow nasal cannula (HFNC). However, the physiological mechanisms of this system are unclear. In the current study, various methods were used to investigate the physiological mechanisms of an HFNC in healthy volunteers. METHODS: The physiological mechanisms of the constant-flow and constant-pressure models of HFNC were studied in 10 healthy volunteers by the oesophageal balloon method, the electrical impedance method and the forced oscillation technique (FOT)...

OBJECTIVE: To investigate the value of high-flow nasal cannula oxygen therapy after extubation in patients with acute respiratory failure. METHODS: A single-center, prospective, randomized, controlled pilot trial was conducted between January 2013 and December 2014. Sixty enrolled patients were randomized immediately after extubation into either a high-flow nasal cannula group (n=30) or an air entrainment mask group (n=30) at a fixed inspired oxygen fraction (40%)...

BACKGROUND: Heated and humidified high-flow nasal cannula (HFNC) is a widely used form of respiratory support; however, data regarding optimal flows for a given patient size or disease state are lacking. A comprehensive study of the physiologic effects of HFNC is needed to better understand the mechanisms of action. The objective of the current study was to quantify the effect of HFNC settings in age-specific, anatomically correct nasal airways and spontaneously breathing lung models...

High flow nasal cannula (HFNC) is increasingly used in pediatric patients suffering from respiratory failure. In some disease processes, patients may also benefit from aerosol therapy. Therefore, the use of HFNC to deliver aerosolized medications is a convenient and attractive option. Areas covered: This review aims to appraise available evidence concerning the efficiency of aerosol nebulized therapy delivery using HFNC in pediatric patients. Expert commentary: Delivery of aerosol particles is a very complex process and depends on the use of oxygen vs...

Objective: The objective of this study was to compare efficacy of continuous positive airway pressure (CPAP) and heated humidified high-flow nasal cannula (HHHFNC) as noninvasive respiratory support in post-extubation period in very low birth weight (VLBW) infants. Method: This retrospective study enrolled 136 neonates, ≤32 weeks gestation and ≤1500 grams birth weight, requiring noninvasive respiratory support during post-extubation period. Results: There was no significant difference in post-extubation failure in HHHFNC group when compared with CPAP group ( p  > 0...

During noninvasive bilevel positive airway pressure (BiPAP) ventilation it is found that several times patients are unable to maintain oxygen saturation and develop breathing difficulty despite its high setting and high oxygen flow, further management requires invasive positive pressure mechanical ventilation. Increasing oxygen concentration inside the BiPAP mask using nasal cannula with addition of another flow meter not only increase oxygen saturation but also make the patient more comfortable and prevent intubation and its complications...

PURPOSE: Acute respiratory failure remains a common hazardous complication in immunocompromised patients and is associated with increased mortality rates when endotracheal intubation is need. We aimed to evaluate the effect of high-flow nasal cannula oxygen therapy (HFNC) compared with other oxygen technique for this patient population. METHODS: We searched Cochrane library, Embase, PubMed databases before Aug. 15, 2017 for eligible articles. A meta-analysis was performed for measuring short-term mortality (defined as ICU, hospital or 28-days mortality) and intubation rate as the primary outcomes, and length of stay in ICU as the secondary outcome...

INTRODUCTION: To evaluate the efficacy of high-flow nasal cannula (HFNC) in the rate of intubation and mortality for patients with acute hypoxemic respiratory failure. METHODS: We searched Pubmed, EMBASE, and the Cochrane Library for relevant studies. Two reviewers extracted data and reviewed the quality of the studies independently. The primary outcome was the rate of intubation; secondary outcome was mortality in the hospital. Study-level data were pooled using a random-effects model when I2 was >50% or a fixed-effects model when I2 was <50%...

BACKGROUND: High-flow nasal cannula (HFNC)(1) is a technique of oxygen supply, initially being used as a potentially less-invasive alternative to nasal continuous positive airway pressure (nCPAP)(2) for premature infants/neonates, which nowadays crosses the border of neonatal care. HFNC builds up a positive end-expiratory pressure (PEEP)(3) but lacks the opportunity for continuous monitoring. Therefore, pressure-depending complications are a risk. Our goal was to evaluate the current use of HFNC in Germany regarding indications, techniques of application and complications experienced...

OBJECTIVES: To determine the predictive factors for the outcome of high-flow nasal cannula (HFNC) therapy in a pediatric intensive care unit (PICU). MATERIALS AND METHODS: We prospectively included all patients with acute respiratory distress/failure aged 1month to 18years who were admitted to the PICU between January 2015 and May 2016 and treated with HFNC as a primary support and for postextubation according to our pre-established protocol. HFNC failure was defined as the need for escalation to non-invasive ventilation (NIV) or invasive mechanical ventilation (MV)...

Pneumocephalus (PNC) is a condition in which when air is trapped inside the intracranial vault. The causes are varied, but include trauma and intracranial surgery. Treatment of PNC typically consists of augmenting patient oxygenation with the attempt of washing out pulmonary nitrogen, creating a gradient in which nitrogen in the intracranial air bubble diffuses out of the lungs via the blood. Though several high flow methods have been tested, the ideal mode of oxygenation has not fully been investigated. Here we present 3 cases of post-operative PNC who we felt were symptomatic from PNC...

Mechanical ventilation is the most used short-term life support technique worldwide and is applied daily for a diverse spectrum of indications, from scheduled surgical procedures to acute organ failure. This state-of-the-art review provides an update on the basic physiology of respiratory mechanics, the working principles, and the main ventilatory settings, as well as the potential complications of mechanical ventilation. Specific ventilatory approaches in particular situations such as acute respiratory distress syndrome and chronic obstructive pulmonary disease are detailed along with protective ventilation in patients with normal lungs...
