Filter by:This study focuses on the evaluation of various factors repeatedly discussed in relation to the impaired sedation of intubated ventilated COVID-19 patients. The sedation response of >100 moderately to severely affected COVID-19 ARDS was evaluated. The sedation level was measured at the bedside using the Richmond Agitation and Sedation Scale and ventilator synchrony. The evaluation was performed according to the static evaluation plan with respect to age, storage therapy and organ failure.
The Evone® ventilator is a new device capable of lung ventilation through a narrow-bore cannula, the Tritube.Two ventilation modes are possible: high frequency jet ventilation (HFJV) and flow-controlled ventilation (FCV). In this prospective pilot study the efficacy of FCV using the Evone® ventilator and Tritube is investigated when compared with Volume Controlled Ventilation (VCV) via a normal tracheal tube.
Brief Summary Short description of the protocol intended for the lay public. Include a brief statement of the study hypothesis. (Limit: 5000 characters) Example: The purpose of this study is to determine whether prednisone, methotrexate, and cyclophosphamide are effective in the treatment of rapidly progressive hearing loss in both ears due to autoimmune inner ear disease (AIED). This project is part of a research field on the role, not yet fully understood, of atmospheric pollution, especially from road traffic, on respiratory health and allergies, particularly on the development / onset of symptoms and functional disturbances. The ultrafine fraction of particles (UFPs - particles smaller than 100 nm in diameter) is of recent interest because of their ability to induce inflammatory effects, oxidative stress and may contribute to the exacerbation of asthma symptoms in susceptible individuals. UFPs, with their high number concentration and surface area and their small diameter are able not only to convey other contaminants, but also to contribute to a high deposition efficiency, into the alveoli in the lungs. Recently it appeared relevant to be interested in black carbon (BC), components of PM2.5 (particulate matter with a diameter less than 2.5 micrometers), suspected of being responsible for their toxicity. Current epidemiological knowledge of the effects of UFPs and BC are few as compared to those on fine particles. Some professionals, such as police, drivers (taxis, truckers ...), delivery men, postal workers, workers on roads and highways, etc. are heavily exposed, during their working hours, to air pollution due to road traffic. These occupational groups appear to be at greater risk for developing respiratory, cardiovascular and neurological diseases than the general population. Occupational exposure to diesel exhaust has been associated with an increased risk of lung cancer mortality and chronic obstructive pulmonary disease. Occupational exposure to UFPs and BC has rarely been measured due to a lack of suitable devices. Therefore, this project's originality consists in measuring UFPs and BC by using portable devices developed in the recent years. The use of these devices, linking their recordings with ventilatory measures and repeating them, offers the rare opportunity to study the short-term respiratory health impact of this occupational exposure, which has never been described in the literature. Our research aims to: 1/ quantify the occupational exposure of taxi drivers to UFP, BC, oxides of carbon (CO, CO2) and to nitrogen dioxide (NO2), 2/ identify spatio-temporal variability and patterns of exposure related to occupational tasks, 3/ study the impact of this occupational exposure to UFP and BC on ventilation performances and respiratory symptoms.
Many post-operative complications arise from patients who breathe inadequately. Inadequate respiration, whether the result of surgery or the anesthesia, causes a decrease in blood oxygen saturation and an increase in carbon dioxide partial pressure. Both of these surrogate measurements of respiration may pose a challenge to measure. Some administer exogenous oxygen to all patients as they leave the operating room in order to maintain the blood oxygen saturation. This renders the oximeter a less sensitive metric of depressed respiration. In the face of decreased respiration, the carbon dioxide levels continue to increase slowly and often go undetected unless blood gases are measured. Indeed carbon dioxide blood levels are the only metric to detect inadequate ventilation using this surrogate index. Monitoring ventilation is a serious challenge outside of critical care settings. In fact, there are no monitors available that can measure tidal volume or relative tidal volume outside of these settings. Linshom is a novel instrument that tracks relative respiration by measuring the excursions of the temperature swings between inspiration and expiration and normalizing them to the patient's breathing. This monitor may be the first non-invasive monitor to measure relative tidal volume in non-critical care settings. The purpose of this study is to determine whether a non-invasive, temperature-based respiratory instrument can track tidal volume (Vt) in patients. The investigators hypothesize that the Linshom device can accurately and consistently track tidal volume as measured by closed loop mechanical ventilator.
An abnormally high V̇E/V̇CO2 response to exercise is a key pathophysiological feature of patients with chronic cardiopulmonary disease that is associated with adverse health outcomes. It follows that any intervention capable of decreasing the V̇E/V̇CO2 response to exercise has the potential to improve clinical and/or patient-reported outcomes. The investigators of this trial will compare the effects of orally administered sodium chloride (4 g, placebo) and sodium bicarbonate (0.3 g/kg of body mass) on ventilation, breathing pattern, dynamic operating lung volume, gas exhange, cardiovascular, metabolic and symptom parameters during symptom-limited, high-intensity, constant-work-rate cycle exercise testing in healthy adults aged 20-40 years.
The main objective of this study is to demonstrate that the only administration of L-citrulline, can improve immune functions in critically ill patients at high risk of nosocomial infection.
The purpose of the present study is to determine the utility and effectiveness of combined inspiratory (IMT) and expiratory muscle training (EMT) in improving ventilatory function in people who are disabled by long-term stroke (greater than 8 months following onset) with hemiparesis or hemiplegia. xx subjects will be randomized into 2 parallel groups in which the experimental group will undergo combined IMT and high-resistance EMT and the comparison group will undergo IMT with low- resistance EMT. Both training techniques involve breathing through a tube with known amounts of resistance. Subjects will perform the breathing maneuvers for 10 repetitions, twice daily, 5 days per week for 4 weeks, in the home environment. Adherence will be monitored by reminder telephone calls at least weekly. Outcomes will be assessed using maximum inspiratory and expiratory pressures and standard pulmonary function testing.
The ventilation (respiratory rate, tidal volume and end-tidal CO2) was monitored for patients receiving procedural sedation during endoscopy procedures in order to observe what changes commonly occur.
