Filter by:Artificial intelligence (AI) shows promising in identifying abnormalities in clinical images. However, systematically biased AI models, where a model makes inaccurate predictions for entire subpopulations, can lead to errors and potential harms. When shown incorrect predictions from an AI model, clinician diagnostic accuracy can be harmed. This study aims to study the effectiveness of providing clinicians with image-based AI model explanations when provided AI model predictions to help clinicians better understand the logic of an AI model's prediction. It will evaluate whether providing clinicians with AI model explanations can improve diagnostic accuracy and help clinicians catch when models are making incorrect decisions. As a test case, the study will focus on the diagnosis of acute respiratory failure because determining the underlying causes of acute respiratory failure is critically important for guiding treatment decisions but can be clinically challenging. To determine if providing AI explanations can improve clinician diagnostic accuracy and alleviate the potential impact of showing clinicians a systematically biased AI model, a randomized clinical vignette survey study will be conducted. During the survey, study participants will be shown clinical vignettes of patients hospitalized with acute respiratory failure, including the patient's presenting symptoms, physical exam, laboratory results, and chest X-ray. Study participants will then be asked to assess the likelihood that heart failure, pneumonia and/or Chronic Obstructive Pulmonary Disease (COPD) is the underlying diagnosis. During specific vignettes in the survey, participants will also be shown standard or systematically biased AI models that provide an estimate the likelihood that heart failure, pneumonia and/or COPD is the underlying diagnosis. Clinicians will be randomized see AI predictions alone or AI predictions with explanations when shown AI models. This survey design will allow for testing the hypothesis that systematically biased models would harm clinician diagnostic accuracy, but commonly used image-based explanations would help clinicians partially recover their performance.
Detection and relief of dyspnea in mechanically ventilated patients is a priority. Optimization of mechanical ventilation settings is unfortunately often insufficient to relieve dyspnea in patients entering the weaning process. Pharmacological treatments are effective but their use is likely to delay separation with the ventilator. Promoting the development of non-pharmacological interventions is therefore an interesting avenue. The hypothesis is that the application of high-flow humidified nasal air in orotracheally intubated patients can decrease the work of breathing and relieve dyspnea at the time of weaning from mechanical ventilation. Patients will be exposed to stepwise increase in high flow nasal air (0 L/min, 30 L/min, 50 L/min and 70 L/min) before to undergo a 60 minutes spontaneous breathing trial. During the protocol, dyspnea, inspiratory effort, respiratory drive, respiratory muscles electromyogram (EMG) and patient's comfort will be assessed.
Retrospective observational study performed in a internal medicine ward of a French university hospital. Included patients were hospitalized for acute shortness of breath who have benefited from a eFOCUS which was defined as a focused cardiac Ultrasound with utilization of Doppler measurements. The objectives were the therapeutic and diagnosis changes induced by eFoCUS. The primary endpoint was defined by the pooled introduction or discontinuation of diuretics, antibiotics or anticoagulants associated with eFoCUS results.
As Acute respiratory failure (ARF) is a challenging serious condition especially when it necessitates intubation to deliver mechanical ventilation which is a fundamental strategy for supporting the respiratory function when the patient can't bear all work of breathing. Even if it represents a life-saving procedure, mechanical ventilation (MV) is associated to life-threatening complications as respiratory muscle dysfunction, and atrophy that lead to long stay in intensive care unit (ICU) and higher mortality. Weaning difficulty is experienced in nearly 30 percent of critically ill patients. The decision to extubate mechanically ventilated patients should be aimed at preventing both the risk of premature liberation from MV which is associated with poor outcome and the risk of delayed extubation which increases the complications of prolonged MV and there is increasing evidence that MV itself may adversely affect the diaphragm's structure and function, which has been termed ventilator-induced diaphragmatic dysfunction (VIDD). The combination of positive pressure ventilation and positive end-expiratory pressure may unload the diaphragm which leads to changes in myofibril length and rapid atrophy that occurs within hours of MV, caused by an imbalance between protein synthesis and proteolysis, lead to a large reduction in the inspiratory pressure generated by the diaphragm.
Stable patient with ARF spontaneously breathing light sedation (not too awake but with stable breathing pattern) and EAdi >8 uV. Four modes of mechanical ventilation were performed under different support level for the measuring of EAdi, air way pressure and other parameters.
Coronavirus Disease (COVID-19) is characterized by a hypercoagulable state, sometimes difficult to be managed with heparin. Bivalirudin, a member of the direct thrombin inhibitor drug class, offers potential advantages compared to heparin, including to its ability to exert its effect by directly attaching to and inhibiting freely circulating and fibrin-bound thrombin. Investigators have therefore designed this pilot open-label randomized controlled trial to assess if a off-label infusion of bivalirudin may reduce thrombosis, mortality, Intensive Care Unit (ICU) length of stay and increase ventilator free days of patients admitted in ICU for acute respiratory failure due to COVID-19, as compared to first-line treatment with heparin.
Objectives: Failure of extubation of patients on mechanical ventilation is one of the common problems in the ICU. Aim of work: To evaluate the validity of lung ultrasound score in prediction of weaning outcomes and post-extubation distress.
Clinicians perform rapid sequence induction, laryngoscopy, and tracheal intubation for more than 5 million critically ill adults as a part of clinical care each year in the United States. One-in-ten emergency tracheal intubations is complicated by life-threatening hypoxemia. Administering supplemental oxygen prior to induction and intubation ("preoxygenation") decreases the risk of life-threatening hypoxemia. In current clinical practice, the most common methods for preoxygenation are non-invasive positive pressure ventilation and facemask oxygen. Prior trials comparing non-invasive positive pressure ventilation and facemask oxygen for preoxygenation have been small and have yielded conflicting results. A better understanding of the comparative effectiveness of these two common, standard-of-care approaches to preoxygenation could improve the care clinicians deliver and patient outcomes.
Clinicians perform rapid sequence induction, laryngoscopy, and tracheal intubation for more than 5 million critically ill adults as a part of clinical care each year in the United States. Failure to intubate the trachea on the first attempt occurs in more than 10% of all tracheal intubation procedures performed in the emergency department (ED) and intensive care unit (ICU). Improving clinicians rate of intubation on the first attempt could reduce the risk of serious procedural complications. In current clinical practice, two classes of laryngoscopes are commonly used to help clinicians view the larynx while intubating the trachea: a video laryngoscope (equipped with a camera and a video screen) and a direct laryngoscope (not equipped with a camera or video screen). For nearly all laryngoscopy and intubation procedures performed in current clinical practice, clinicians use either a video or a direct laryngoscope. Prior research has shown that use of a video laryngoscope improves the operator's view of the larynx compared to a direct laryngoscope. Whether use of a video laryngoscope increases the likelihood of successful intubation on the first attempt remains uncertain. A better understanding of the comparative effectiveness of these two common, standard-of-care approaches to laryngoscopy and intubation could improve the care clinicians deliver and patient outcomes.
Second analysis of data prospectively collected during an investigation assessing the clinical characteristics of patients admitted for hypoxemic acute respiratory failure (hARF) related to novel coronavirus 19 disease (COVID-19). In particular, the primary aim of the present analysis is to assess the effects of recruiting maneuver and prone positioning on lung aeration evaluated through lung ultrasound in patients undergoing invasive mechanical ventilation
