Noninvasive respiratory support in acute hypoxemic respiratory failure associated with COVID-19 and other viral infections

2020

ABSTRACTIntroductionNoninvasive respiratory support (NRS) such as noninvasive ventilation (NIV) and high flow nasal therapy (HFNT) have been used in the treatment of acute hypoxemic respiratory failure (AHRF) related to the coronavirus disease (COVID-19) and other viral infections. However, there is a lack of consensus in favor of or against NRS use due to the risks of worsening hypoxemia, intubation delay, and aerosols environmental contamination associated with the use of these tools. We aimed to summarize the evidence on the use of NRS in adult patients with COVID-19 and other viral pneumonia (i.e. H1N1, SARS, MERS) and AHRF. We also searched for studies evaluating the risk of aerosoliza…

Heat pipe controlled syntheses of ionic liquids in microstructured reactors

2009

Abstract The combination of a heat pipe and a microstructured reactor allows to perform highly exothermal reactions under safe conditions. First experiments for the synthesis of 1,3-dimethylimidazolium-triflate from 1-methylimidazol and methyl triflate showed that at high flow rates of more than 5 ml/min through a single 300 μm × 500 μm wide and 400 mm long channel quantitative conversion could be achieved. This chemical reaction, known for extreme heat release, can be retained under thermal control even at much higher flow rates.

High-Flow Nasal Therapy in Acute and Chronic Respiratory Failure: Past, Present, and Future

2023

High-flow nasal therapy (HFNT) was introduced into clinical practice in the early 2000s as a form of noninvasive respiratory support (NIRS). During the last 20 years, a growing body of evidence has shown the value of this intervention in the management of acute and chronic respiratory failure.

Prevalence and 30-Day Mortality in Hospitalized Patients With Covid-19 and Prior Lung Diseases.

2021

Patients with pre-existing respiratory diseases in the setting of COVID-19 may have a greater risk of severe complications and even death.A retrospective, multicenter, cohort study with 5847 COVID-19 patients admitted to hospitals. Patients were separated in two groups, with/without previous lung disease. Evaluation of factors associated with survival and secondary composite end-point such as ICU admission and respiratory support, were explored.1,271 patients (22%) had a previous lung disease, mostly COPD. All-cause mortality occurred in 376 patients with lung disease (29.5%) and in 819 patients without (17.9%) (Previous lung disease is a risk factor for mortality in patients with COVID-19.…

High flow nasal therapy versus noninvasive ventilation as initial ventilatory strategy in COPD exacerbation: a multicenter non-inferiority randomized…

2020

Abstract Background The efficacy and safety of high flow nasal therapy (HFNT) in patients with acute hypercapnic exacerbation of chronic obstructive pulmonary disease (AECOPD) are unclear. Our aim was to evaluate the short-term effect of HFNT versus NIV in patients with mild-to-moderate AECOPD, with the hypothesis that HFNT is non-inferior to NIV on CO2 clearance after 2 h of treatment. Methods We performed a multicenter, non-inferiority randomized trial comparing HFNT and noninvasive ventilation (NIV) in nine centers in Italy. Patients were eligible if presented with mild-to-moderate AECOPD (arterial pH 7.25–7.35, PaCO2 ≥ 55 mmHg before ventilator support). Primary endpoint was the mean di…

Weaning Premature Infants from Nasal Continuous Positive Airway Pressure - Current Practice and Scientific Evidence.

2017

Abstract Objective In the past decade, a number of trials have been conducted to determine the optimal strategy of weaning premature infants from nasal continuous airway pressure (nCPAP). However, a paucity of information exists on how weaning is actually performed in clinical routine. Aim of this study was to investigate the current practice of weaning premature infants from nCPAP in Germany. Methods An online survey was performed in German tertiary care neonatal units. Results All 160 German tertiary care units were contacted. Replies were retrieved from 85/160 (53%) units, of which 83/160 (52%) completed the questionnaire. 66/83 (80%) respondents indicated to wean without the use of form…

Nurses' experiences by using heated humidified high flow cannula to premature infants versus nasal continuous positive airway pressure

2016

Abstract Background Some premature infants are now being treated with heated humidified high flow nasal cannula (HHHFNC) instead of nasal continuous positive airway pressure (nCPAP). Purpose To explore nurses' experiences of using HHHFNC compared with nCPAP for premature infants. Method Six qualitative in-depth interviews were completed with nurses at two different newborn intensive care units. Results Preterm infants showed greater satisfaction with HHHFNC than nasal continuous positive airway pressure. HHHFNC was also associated with fewer pressure injuries and less facial discomfort, and an increased bonding between baby and parent. However, HHHFNC gave less ventilation support than nCPA…

High flow nasal therapy in perioperative medicine: from operating room to general ward

2018

Abstract Background High flow nasal therapy (HFNT) is a technique in which humidified and heated gas is delivered to the airways through the nose via small nasal prongs at flows that are higher than the rates generally applied during conventional oxygen therapy. The delivered high flow rates combine mixtures of air and oxygen and enable different inspired oxygen fractions ranging from 0.21 to 1. HFNT is increasingly used in critically ill adult patients, especially hypoxemic patients in different clinical settings. Main body Noninvasive ventilation delivers positive pressure (end-expiratory and inspiratory pressures or continuous positive airway pressure) via different external interfaces. …
