Carbon Monoxide Breath Sensor System (COBSS) Performance, Human Factors, and Usability Assessment in a Single Visit

Endurance: Measurement: Carbon monoxide levels in the exhaled breath of research subjects using two different types of measurement methods can be easily determined non-invasively. Determine the correlation between the measured CO levels of the study CO breath sensor and the predicate CO breath sensor. NOTES: The study design allows for the evaluation of a results endpoint and human factors endpoint in a single study.

Fractional Carbon Dioxide Laser Therapy of the Vagina for Treatment of Urogenital Symptoms in Women

According to the case report and case series results, laser therapy of the vaginal tissues is well tolerated by patients and does not pose significant risks to the patient. This is a prospective observational review of women undergoing vaginal treatment with the fCO2 laser for a wide variety of patients with vulvovaginal, sexual, and/or urologic problems. Different physical examinations and patient questionnaires will determine the effects of fCO2 therapy.

Adenoid Cystic Carcinoma and Carbon Ion Only Irradiation

Adenoid cystic tumors are unusual head and neck tumors. In about four weeks, irradiation is administered - much shorter than combination therapy - for about four weeks; patients are followed for another five years after the start of therapy. Carbon ions alone is expected to elevate local tumor control rates from 60% to 70% after 5 years. 175 patients are included in an attempt to refute the null hypothesis with a power of 80% and a significance level of 5%.

Carbon-Dioxide Flushing Versus Saline Flushing in Thoracic Endovascular Aortic Repair to Reduce Neurological Injury: A Pilot Randomised Controlled Trial

The re-lining of the thoracic aorta is the re-lining of the thoracic aorta to prevent life-threatening haemorrhage and death from rupture. Stents are flushed with saline prior to insertion into the patient to remove air and prevent air from entering the brain, which may lead to a condition of brain injury called vascular brain infarction. Carbon-dioxide has been used extensively in cardiac surgery to remove air from the chest cavity to prevent peri-procedural cerebral air embolization. We speculate that flushing the stent-grafts with carbon-dioxide may be more effective at removing air from the stent-grafts than a saline flush. Participants in the stent-graft deployment phase of TEVAR will continue intraoperatively for continuous transcranial doppler monitoring of the middle cerebral artery to look for cerebral air embolisation at the stent-graft deployment phase.

Microparticles Blood Level in Acute Carbon Monoxide Poisoning

The delayed neurological disease is one of CO poisoning's potential risks. The increase in circulating microparticles in mice exposed to CO intoxication was shown in the Mouse model study. Compared to a population of healthy controls, our research group found a potential rise in circulating microparticles in patients with CO poisoning. In addition, the types of microparticles involved in CO poisoning will be identified. All patients who require a hyperbaric treatment due to an acute CO poisoning epidemic in the area afferent to Nursing House Habilita "I Cedri" located in Fara Novarese are included in the study, and a healty monitor will be identified for every two patients. A blood sample in sodium citrate will be taken in the patient's hyperbaric room before the therapy, and at the end of the procedure, a new blood sample will be taken.

Impact of Restaurant Menu Carbon Footprint Labeling on Consumers Purchase Intentions and Perceptions

The effects of restaurant menu carbon footprint labels will be investigated by this online randomized controlled clinical trial to see consumers' preferences and impressions of restaurant menu items. After selecting, they will be asked to provide information about their experiences of menu items and carbon footprint labels. The most important result will be the average carbon footprint of menu items chosen from the online menu.

Reshaping Food Choice at University of Michigan Dining Halls to Accelerate Carbon Neutrality

Therefore, lowering red meat intake can have transformative effects on climate change. Our multidisciplinary team of researchers and dining service is examining the carbon impact of evidence-based behavior change efforts to curb red meat consumption at University of Michigan dining halls. We'll investigate the results of three "nudge" interventions to reduce red meat intake in three randomly assigned treatment dining halls vis-u00e0-versus three paired control dining halls using an experimental framework. 1 collects data on meals served during each intervention period to determine the separate and combined effects of the interventions on red meat intake; two conduct e-mail interviews with students to find treatment effect heterogeneity and sociodemographic determinants of food choice; and, three determine focus group discussions and interviews with students and dining staff to determine implementation feasibility; and, three research, respectively, will determine implementation feasibility.

Extra-Corporeal Carbon Dioxide Removal for Acute Decompensation of Chronic Obstructive Pulmonary Disease: A Randomized Clinical Trial (The ORION Study)

Non-invasive ventilation is non-invasive ventilation for patients with COPD exacerbation that require ICU admission for management of acute respiratory disease and severe respiratory acidosis. Since ECCO2R has been used in patients with acute hypercapnic respiratory failure, patients with acute respiratory failure can be treated with extracorporeal circuits that remove CO2 and prevent respiratory acidosis from extending. However, hospital mortality was significantly lower in NIV-plus-ECCO2R" than in patients treated with "NIV-only" [8% vs. 33%], respectively; a new matched cohort study with historical controls found that the hazard of being intubated was three times higher in patients treated with NIV-only" and "NIV-only" in patients at risk of NIV-related mortality in patients treated with NIV-only" than in patients treated with compared NIV-only] in patients treated in NIV-only compared to compared to "NIV-only"ROCCO2R" and NIV-only" in compared to "NIV-only" in patients treated with NIV-only" in patients at risk of NIV-only NIV-only"NIV-only"NIV-only"NIV-only"NIV-only"NIV-only"RIVIV-only"NIV-only" and NIV-only" " and The majority of patients were either safely weaned from mechanical ventilation or maintained on NIV, avoiding intubation, according to a new systematic review.
