Filter by:Background: In Intensive Care Unit (ICU) patients, dyspnea is frequent, severe and exerts unfavorable effects on the short, medium and long term. Detection and quantification rely on the patient's self-reporting abilities. However, more than half of the patients in the ICU are unable to report their sensations. Therefore, the risk is to miss the evaluation of dyspnea and the potential benefits associated with its control. Observational scales, based on physiological and behavioral changes related to dyspnea (such as the Mechanical Ventilation Respiratory Distress Observational Scale MV-RDOS), are promising alternative tools for the detection of dyspnea in non-communicating patients. However, their routine use is not standardized, is not supported by any recommendation, but above all, relies largely on the subjective observation of the facial expression of fear or the abdominal paradox. There is a need for alternatives to the visual analogue dyspnea scale (D-VAS) for the detection of dyspnea in non-communicating intubated patients. Analysis of brain cortical activity modifications during dyspnea could be an alternative to the dyspnea self-report (D-VAS) in the ICU and could improve the performance of observational dyspnea scales. Hypothesis: 1) dyspnea during a spontaneous breathing trial (SBT) is associated with premotor cortex activation identifiable using functional Near-Infrared Spectroscopy (fNIRS); 2) replacing the items "abdominal paradox" or "facial expression of fear" by HbO2 level could improve the performance of the MV-RDOS to predict dyspnea in non-communicating intubated patients; 3) HbO2 level change identified using fNIRS performs well in predicting SBT outcome
Bronchial asthma may present with symptoms other than the commonly reported complaints (cough, chest tightness, shortness of breath and wheezing). Less common symptoms include chronic or recurrent productive cough, inspiratory dyspnoea or recurrent pneumonia. Children presenting with these symptoms are often diagnosed with asthma bronchiale and benefit from antiasthmatic management.
The purpose of this research is to determine the effect that repeated, personalized virtual reality experiences have on symptom severity, comparing self-reported symptom severity both pre and post each session, and overtime across sessions. We will also determine if this intervention results in a high rating of presence in VR, and if presence is related to the magnitude of the change in symptoms.
To evaluate the extent to which a 12-week respiratory rehabilitation program consisting of inspiratory and expiratory breathing exercises compared to expiratory breathing exercises alone will help to improve shortness of breath, respiratory symptoms, breathing function, distance walked, and quality of life in those who are experiencing persistent shortness of breath after having had COVID-19. Measurements will take place at the beginning, 6 weeks, and at 12 weeks in the study.
The goal of this mixed methods study is to learn about cranial electrotherapy stimulation (CES) using Alpha-Stim AID in anxiety related to breathlessness in advanced lung diseases. The main question[s] it aims to answer are: - Is CES using Alpha-Stim AID acceptable and tolerable as a potential treatment in the management of anxiety in patients who experience breathlessness due to advanced chronic respiratory disease? - What are the key factors that will inform the design of a study to examine its potential clinical effectiveness? Participants will choose whether they want to trial the CES for eight weeks or be in a parallel control group. They will complete daily diaries, questionnaires about anxiety, breathlessness, sleep, quality of life and depression, and an end of study qualitative interview. Researchers will compare those using the CES and those receiving standard care to see if there are any indications of difference in anxiety and other symptoms experienced.
The goal of this NIH-sponsored study is to characterize three biomarkers derived from 129Xe gas exchange MRI and to understand how they change in response to interventions.
The evolution of amyotrophic lateral sclerosis (ALS) is marked by dyspnea, anxiety and pain, major determinants of suffering induced by this disease. The only palliative treatment for respiratory failure is non-invasive ventilation (NIV), which compensates failing respiratory muscles and relieves dyspnea, improves quality of life and increases life expectancy. In ALS patients, the persistence of dyspnea outside of NIV sessions has highlighted the need for therapeutic alternatives in the treatment of persistent dyspnea, including immersive virtual reality (IVR) and auditory distraction through music (music therapy). This study evaluates the effect of IVR on respiratory discomfort in ALS patients with persistent dyspnea treated with NIV.
Sepsis is organ dysfunction secondary to an inappropriate host response to infection. In the most severe cases, circulatory failure necessitating the introduction of vasopressor therapy is called septic shock. Sepsis and septic shock are life-threatening systemic organ dysfunctions requiring hospitalization in a critical care unit. According to several studies, sepsis accounts for around 30% of patients in these units. In this patient population, mortality in the critical care unit or in hospital is 25.8% and 35.3% respectively. Among the organ dysfunctions associated with sepsis, striated skeletal muscle damage is frequent and possibly severe. The literature refers to this as sepsis-induced myopathy, and describes three main mechanisms: mitochondrial dysfunction, exacerbated proteolysis and altered muscle membrane excitability. Of all the striated skeletal muscles that can be affected, the diaphragm and the muscles of the thoracic and abdominal wall play a major role in breathing. The diaphragm remains the main muscle involved in breathing. Its physiology is twofold. Firstly, through its contraction, the diaphragm is responsible for the lateral movement of the lower ribs, thus increasing the transverse diameter of the thorax. This first action is commonly referred to as "insertional". At the same time, lowering the phrenic center of the diaphragm increases abdominal pressure. Its distinctive upwardly convex domed appearance means that it is intimately in contact with both the chest wall and the abdominal cavity. This particular area of contact is called the apposition zone. It is on this zone, under the action of the abdominal compartment, that positive pressure also generates an outward thrust from the medial face of the lower ribs, a second action commonly referred to as "appositional". A number of studies, including that carried out by our team (US_DIAMONDS, NCT 02474797), have identified a high prevalence of diaphragmatic damage in patients with sepsis or septic shock. This can be as high as 60%. This diaphragmatic dysfunction would then be associated with a higher mortality rate in hospital and at D90 of discharge. The clinical evolution of post-resuscitation patients remains a little-studied subject. However, patients may present muscle dysfunctions in the longer term after a stay in intensive care. In our study, we demonstrated that less than half of patients recovered from diaphragmatic dysfunction on discharge from the critical care unit. In addition, Borges RC et al. found a significant decrease in the cross-sectional area of the rectus femoris at discharge, compared with the same measurement taken at D+2 of admission to the critical care unit. Finally, the impact of muscle dysfunction on dyspnoea during sepsis and after its resolution is uncertain. Similarly, the impact of muscle dysfunction and dyspnoea on quality of life is unknown. Sepsis is associated with muscle dysfunction of multiple mechanisms. The aim of this study is to assess the immediate and longer-term impact of muscle dysfunction on muscle, dyspnea and quality of life in patients with abdominal sepsis ("Abdominal sepsis" group) and patients with extra-abdominal sepsis ("Extra-abdominal" group). Depending on the location of sepsis, this study will enable us to assess and potentially confirm the preferential effect of abdominal sepsis on diaphragm function.
Seismocardiography (SCG) measures the thoracic vibrations caused by the cardiac contraction and ejection of blood into the great vessels. Current smartphones with gyroscopes and accelerometers can measure these vibrations. Based on these components we measure and quantify the cardiac kinetic energy (kinocardiography) in order to differentiate dyspnea of cardiac origin from dyspnea of other origin. The study is conducted in an emergency service where a smartphone performs the measurement during 3 minutes. The results of the kinocardiography-based classification are then compared to the final diagnosis made by a physician. Currently, 235 patients have been included in the clinical study since May 2022. This rapid and non-invasive measurement allows the aid-to-diagnosis of heart failure without being influenced by other factors like the renal function for example that can be NT-pro BNP blood marker.
The purpose of this study is to assess the efficacy of Caption LungAI.
