Filter by:High flow nasal oxygen therapy (HFNO) is an established modality in the supportive treatment of patients suffering from acute hypoxemic respiratory failure. The high humidified gas flow supports patient's work of breathing, reduces dead space ventilation, and improves functional residual capacity while using an unobtrusive patient's face interface [Mauri et al, 2017; Möller et al, 2017]. As hyperoxia is considered not desirable [Barbateskovic et al, 2019] during any oxygen therapy, the inspired O2 concentration is usually adapted to a pre-set SpO2 target-range of 92-96% in patients without hypercapnia risk, and of 88-92% if a risk of hypercapnia is present [O'Driscoll et al, 2017; Beasley et al, 2015]. In most institutions, the standard of care is to manually adapt the FiO2, although patients frequently have a SpO2 value outside the target range. A new closed loop oxygen controller designed for HFNO was recently developed (Hamilton Medical, Bonaduz, Switzerland). The clinician sets SpO2 targets, and the software option adjusts FiO2 to keep SpO2 within the target ranges. The software option offers some alarms on low and high SpO2 and high FiO2. Given the capability, on the one hand, to quickly increase FiO2 in patients developing sudden and profound hypoxia, and, on the other hand, of automatically preventing hyperoxia in patients improving their oxygenation, such a system could be particularly useful in patients treated with HFNO. A short-term (4 hours vs 4 hours) crossover study indicated that this technique improves the time spent within SpO2 pre-defined target for ICU patients receiving high-flow nasal oxygen therapy [Roca et al, 2022]. Due to its simplicity, HFNO is increasingly used outside the ICU during transport and in the Emergency Room (ER). This environment poses specific challenges, as patients may deteriorate very quickly and depending on patient's flow, healthcare providers can easily be overwhelmed. We thus propose to evaluate closed loop controlled HFNO in ER patients. The hypothesis of the study is that closed loop oxygen control increases the time spent within clinically targeted SpO2 ranges and decreases the time spent outside clinical target SpO2 ranges as compared to manual oxygen control in ER patients treated with HFNO.
Acute hypoxemic respiratory failure (AHRF) is the most common cause of admission in the intensive care units (UCIs) worldwide. We will assess the value of machine learning (ML) techniques for early prediction of ICU death and prolonged duration (>7 days) of mechanical ventilation (MV) in 1,241 patients enrolled in the PANDORA (Prevalence AND Outcome of acute Respiratory fAilure) Study in Spain. The study was registered with ClinicalTrials.gov (NCT03145974). Our aim is to evaluate the minimum number of variables models using logistic regression and four supervised ML algorithms: Random Forest, Extreme Gradient Boosting, Support Vector Machine and Multilayer Perceptron.
Coronavirus 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.
We designed this study to dtermine whether invasive mechanical ventilation (MV) would have an impact on the reclassification of patients with acute hypoxemic respiratory failure (AHRF) -treated previously with non-invasive respiratory support- into categories of severity (mild, moderate, and severe). Our hypothesis is that the assessment of PaO2/FiO2 ratio on PEEP greater or equal to 5 cmH2O after intubation, in patients labeled as mild/moderate/severe AHRF while on non-invasive respiratory support, would identify that a marked proportion of patients would change the degree of severity after a brief period of invasive MV
The goal of this prospective multicentric study is to evaluate the presence of long-term pulmonary sequelae in patients who had required hospitalization for treating COVID-19 pneumonia, trough chest CT and pulmonary function tests (PFT). Secondly we would like to evaluate the possible correlation between the chest CT findings and pulmonary function tests pre-existing co-morbidities and type of therapy used during hospitalization.
NivolisMonitor and NivolisAnton are new devices developed by Vivardis. NivolisMonitor is a generic and autonomous device for remote monitoring of ventilatory parameters generated by ventilatory assistance systems. NivolisMonitor uses its sensors to measure ventilation parameters such as pressure, flow, temperature and relative humidity, Fi02 provided by respiratory treatment devices (NIV, HDN (High Nasal Flow) and Oxygen therapy). NivolisMonitor records this data, stores it and transmits it to the healthcare professionals in charge of the patient. NivolisAnton is a medical device for telemonitoring of transcutaneous capnia, it thus helps to make recordings at the patient's home and to transmit data to healthcare professionals. The main objective of this study is to show that the use of NivolisMonitor and NivolisAnton is done in complete safety and that the clinical performances of these two devices are achieved. For this, the data measured by NivolisMonitor will be compared with the data provided by the treatment devices used by patients at home and the data provided by NivolisAnton will be compared with the data reported by the transcutaneous capnia monitor. The secondary objectives concern the evaluation of the acceptability/usability of the devices by patients and healthcare professionals. This evaluation will take the form of an observational clinical study on 10 patients, including : - a selection of patients already treated with NIV or HDN according to the inclusion/non-inclusion criteria and submission of the information note - an inclusion visit taking place during a routine pulmonological follow-up visit for these patients with collection of the free and informed consent of each patient. The blood gas data collected during this routine consultation will be compiled in the study observation book. - a 3-day monitoring period: - use over 3 days of the NivolisMonitor device at home, with on the last day the completion of the patient acceptability/usability questionnaire - overnight use of NivolisAnton - a teleconsultation to close the study for each patient - completion of the healthcare professional acceptability/usability questionnaire at the end of the study
Chronic hypercapnic respiratory failure (CHRF) in the context of Chronic Obstructive Pulmonary Disease (COPD) and Obesity Hypoventilation Syndrome (OHS) is associated with increased mortality. The availability and effectiveness of domiciliary Non-invasive ventilation (NIV) treatment (when indicated) is key as this treatment can improve quality of life and reduce health-care costs from associated burden of disease. The emerging obesity epidemic means that there is now increased home mechanical ventilation set-ups in patients with obesity related respiratory failure (ORRF), yet there are no alternative treatments for patients struggling with domiciliary NIV. Domiciliary NHF has been shown to improve health related quality of life in stable CHRF in patients with COPD and improve cost effectiveness yet there are no current studies looking at the use of domiciliary NHF and its outcomes in ORRF. The study aims to deliver a pre and post intervention study evaluating patient reported and clinical outcomes in patients using NHF over twelve weeks, who have either COPD or OHS and have been unable to use domiciliary NIV. The study wishes to address key outcomes such as quality of life, clinical effectiveness, compliance and acceptability with the use of domiciliary NHF in both of these patient populations.
In the context of postoperative hypertension in the intensive care units, or after resusitation of hypertensive patients, intravenous antihypertensive drugs are often used. Among those drugs, Nicardipine is an effective drug, but with side effects such as inhibition of pulmonary vasoconstriction. Only preclinical studies have investigated the pathophysiology of this mechanism, and no clinical study have proven its clinical relevance. The aim of this study is to establish the incidence of Nicardipine induced hypoxemia and to compare it to another antihypertensive agent, Urapidil.
This study aimed to present a proof-of-concept that a 30 minutes single-session of low-field thoracic magnetic stimulation (LF-ThMS) on the dorsal thorax can be employed to increase oxygen saturation (SpO2) levels in coronavirus disease (COVID-19) participants significantly. The investigators (Saul M. Dominguez-Nicolas and Elias Manjarrez) hypothesized that the variables associated with LF-ThMS, as hyperthermia, frequency, and magnetic flux density in the dorsal thorax, might be correlated to SpO2 levels in these participants. The investigators designed a single-blind, sham-controlled, crossover study on COVID-19 participants who underwent two sessions of the study (real and sham LF-ThMS), and other COVID-19 participants who underwent only the real LF-ThMS.
Non-Invasive ventilation (NIV) is a life saving intervention for patients with acute respiratory failure (ARF). Some patients are not able to tolerate the NIV intervention and ultimately fail, requiring the use of invasive mechanical ventilation (IMV) and intubation. Sedation may improve a patient's NIV tolerance. However, this practice has not been adopted by intensivists as the risk of over-sedation resulting in respiratory depression, inability to protect the airway, and inadvertent need for intubation are all large deterrents of sedative use in NIV. The Non-invasive Ventilation and Dexmedetomidine in Critically Ill Adults: a Vanguard Pragmatic Randomized Controlled Trial (inDEX) is looking to evaluate the effectiveness of dexmedetomidine compared to placebo in reducing non-invasive ventilation failures in patients admitted to the hospital with acute respiratory failure. The results from this pilot trial, will subsequently inform a large, pragmatic, powered trial to definitively address the question.
