High-flow Nasal Cannula Oxygen Therapy With or Without NIV During the Weaning Period
Acute Respiratory Failure Requiring ReintubationProspective multicenter randomized controlled open-label trial comparing 2 strategies of oxygenation during the post-extubation period in ICU patients at high risk of extubation failure. Patients will be randomized and assigned to one of the two groups, with a 1:1 ratio.
HFNC Alone or Associated With NIV for Immunocompromised Patients Admitted to ICU for Acute Respiratory...
Acute Respiratory FailureImmunosuppressionAcute respiratory failure is the leading cause of ICU admission of immunocompromized patients. In this subgroup of patients, the need for intubation and invasive mechanical ventilation occurs in about 50% of cases and is associated with very a high mortality rate, reaching 70% of cases. Therefore, noninvasive oxygenation strategies have been developed to avoid intubation. More than 15 years ago, 2 trials have suggested that NIV could decrease intubation and mortality rates of immunocompromized patients as compared to standard oxygen through a mask. However these results have not been confirmed in a recent large trial. HFNC is a recent and well-tolerated oxygenation technique. In a recent trial, HFNC alone could decrease mortality and intubation rates in patients with ARF as compared to NIV. Similar findings have been reported in a post-hoc analysis on immunocompromized patients excluding those with profound neutropenia. Likewise in a retrospective monocentric cohort of immunocompromized patients, we reported better outcomes with HFNC than with NIV.
Weaning From Noninvasive Ventilation
Hypercapnic Respiratory FailureWeaning Failure1 moreNoninvasive ventilation (NIV) weaning strategies differ considerably from one another. These strategies have yet not been compared to each other. Therefore, the investigators planned to perform a prospective, randomized, pilot study involving hypercapnic acute respiratory failure patients ready to be weaned off from NIV. The investigators are going to compare the success rate of NIV weaning and the duration of NIV after randomization between 3 NIV weaning methods: gradual decrease in duration of NIV or level of ventilator support, and abrupt discontinuation of NIV.
Non-rebreather at Flush Rate Compared to Bag Valve Mask With Assist
Acute Respiratory FailureThis crossover investigation enrolls healthy volunteers and compares the exhaled oxygen content (FeO2) between the non-rebreather mask at the flush rate and a bag-valve-mask device at the flush rate, used with active positive pressure assistance.

The Effect of Non-invasive Respiratory Support on Outcome and Its Risks in Severe Acute Respiratory...
COVID-19Hypoxemic Respiratory FailureCoronavirus disease (COVID-19) can result in severe hypoxemic respiratory failure that ultimately may require invasive mechanical ventilation in the Intensive Care Unit (ICU). Although lifesaving, invasive mechanical ventilation is associated with high mortality, severe discomfort for patient, long-term sequelae, stress to loved-ones and high costs for society. During the ongoing pandemic high number of invasively ventilated COVID-19 patients overwhelmed ICU capacity. Non-invasive respiratory support, such as high flow nasal oxygen (HFNO) or non-invasive ventilation (NIV) have the potential to reduce the risk for invasive mechanical ventilation and in selected cases ICU admission. However, data from different studies are conflicting and studies performed in COVID-19 patients are of limited quality. Furthermore, identification of early predictors of HFNO/NIV treatment failure may prevent unnecessary delay of initiation of invasive ventilation, which may be associated with adverse clinical outcome. The development and validation of a prediction model, that incorporates readily available clinically data may prove pivotal to fine-tune non-invasive respiratory support. The overall aim of the NORMO2 project is to investigate the role and risks of HFNO and NIV to improve outcome in hospitalized hypoxemic COVID-19 patients.

Effect of Interscalene Block on Ventilatory Function
Respiratory DepressionAnesthesia Morbidity1 moreInterscalene block with local anesthetic impairs ventilation (unilateral diaphragmatic dysfunction). Single injection of local anesthetic induced transitory dysfunction (< 24h). The investigators hypothesized that continuous interscalene block would prolonged ventilatory impairment
Study of the Usability and Efficacy of a New Pediatric CPAP Mask
Obstructive Sleep ApneaRespiratory InsufficiencyThis study will evaluate a newly developed pediatric mask (known as Pixi) on children aged 2-7 using continuous positive airway pressure (CPAP), or Non-invasive ventilation (NIV) treatment. The participants will undergo a monitored sleep study, followed by a 7 night trial of the Pixi mask in the home environment. During the study usability will be measured through questionnaires filled in by the parent and clinician. The study hypothesis is that the usability of the mask will be superior to the patient's usual mask.
The Effects of Airtrapping on Sleep and Breathing in Non Invasive Ventilation (NIV) in COPD
COPDHypercapnic Respiratory Failure15 COPD patients will be surveyed in this prospective randomized crossover pilot study concerning non invasive ventilation. Patients will be treated over 2 nights in randomized order with Ventimotion2 (Weinmann) with and without Airtrap Control under Polysomnography (PSG) surveillance including transcutaneous pCO2 measurement. The sleep quality is judged by evaluating the PSG and pCO2 values over night. Target parameters are respiratory rate, sleep quality and influence of Airtrap Control on pCO2 values over night.
