Active clinical trials for "Respiratory Aspiration"

Asthma and COPD are common chronic diseases of respiratory system. The correct use of inhalers is crucial in terms of efficacy of the treatment, however both asthma and COPD patients quite frequently misuse the inhalers. The objective of this study is to determine the factors influencing the number of inhalation errors committed by asthma and COPD patients when using the inhalers. In included patients the inhalation technique will be evaluated (by both list of inhalation errors and 4 point scale of proper inhaling) by two observers and the below information will be collected: general demographic information and education level information concerning time of diagnosis, the previous course of disease, smoking history, number of previous inhalation techniques training, the sources of information about the inhalation technique and adherence to therapy Asthma Control Test or COPD Assessment Test (respectively for asthma and COPD) assessment of quality of life (St. George's Questionnaire for COPD and Asthma Quality of Life Questionnaire for asthma) cognitive functions assessment using Mini-Mental State Examination the simplified assessment of vision impairments the results of spirometry

Electrical impedance tomography (EIT) is an evolving monitoring tool for respiratory support in neonatal and pediatric intensive care. In this observational study basic EIT parameters will be measured on 20 healthy newborn infants during spontaneous breathing and assess the effect of position changes in ventilation distribution.

Breathing exercises to improve fatigue and quality of life in hemodialysis patients

Background Thoracic or abdominal surgeries are followed by a shorter or longer period of immobilization and after major surgery there is a higher risk of developing cardiorespiratory complications. To prevent these complications, the patient is encouraged to change position and exercise in bed, get out of bed as early and as much as possible after the operation and to breathe with or without aids. There is no general definition of early mobilization and may start within a few hours to a few days after surgery. There is currently a lack of knowledge nationally and internationally about when the mobilization starts and what it contains. Many patients also receive breathing training in connection with the surgery. There is currently no consensus on which method is preferable for which groups of patients. There are similarities and differences in practice in the world regarding postoperative breathing training. There are studies that have mapped practice after primarily thoracic surgery but also abdominal surgery. However, there are no studies that have mapped when the prescribed breathing training starts after different types of operations. The purpose of the study is to map when mobilization and breathing training starts after abdominal and thoracic surgery and what is then performed Method The study will be carried out as a quality follow-up with mapping of practice. Patients ≥ 18 years of age who are undergoing a planned or acute open, keyhole or robot-assisted surgery, who are extubated and who breathe spontaneously will be included. Exclusion criteria are completed plastic, trauma, orthopedic or transplant surgery. The material will be recruited from Swedish university hospitals and county hospitals for 20 days of surgery (Monday through Thursday) for five consecutive weeks. Clinical benefit The study will mean that clinical practice is presented which, with regard to mobilization, is the first study ever that will present when this takes place and what is done and, with regard to breathing training, the first that shows when this training is initiated.

This is a single-center, exploratory positron emission tomography (PET) study of deposition, disposition and brain uptake [11C]nicotine when given to smokers as two different formulations via mybluTM e-cigarette system.

16 patients with American Society of AnesthesioIogy (ASA) physical status I-III will recruited to this study. Patients will divided to the 2 groups. %1.5 Sevoflurane will apply in Group S and %6 Desflurane will apply in Group D. Each groups will divide 2 subgroups. Two lung ventilation will be performed to Group Sa and Group Da, one lung ventilation will be performed to Group Sb and Group Db. At the time point 40.minutes first blood sample will given from patients. Blood sample will be taken at intervals of 10 minutes from groups of two lung ventilation. In groups of one lung ventilation, blood samples will be taken at the time interval of 10 minutes after one lung ventilation started. All blood samples will be assess in Gas Chromatography.

The purpose of this study is to investigate the time course of PF-04764793 concentration in the blood following dosing by oral inhalation from dry powder inhalers.

The purpose of this study is to compare the accuracy of the BiancaMed BM07 breathing frequency indicator device with the respiration rate measured by a SomnoScreen RC Easy device on 20+ human volunteers. This is being carried out in support of a 510(k) submission.

Cyanide poisoning is commonly viewed as a rare but dramatic event, occurring in industrial or laboratory settings as the result of accidental releases of hydrogen cyanide (HCN) gas (e.g. in the case of fire) or salts in the case of suicide attempts. In fact, cyanide poisoning is considerably more common than is generally appreciated. Multiple clinical and post-mortal studies have demonstrated that HCN contributes to the toxicity of fire smoke. Cyanide acts primarily through its strong affinity for the iron-containing heme moiety, binding to numerous critical enzyme systems in the body and rendering them inactive. Of late, increasing attention has been paid to the relationship of cyanide and nitric oxide. The interactions appear to be complex, with cyanide inducing nitric oxide production by binding to N-methyl-D-aspartate (NMDA) receptors, as well as binding to nitric oxide synthase. The latter may be overcome by the presence of nitric oxide synthase inhibitors. Probably, the majority of the cyanide poisoning cases are due to smoke inhalation in closed-space fires. So far, there are no clear data available on the prevalence of cyanide poisoning in smoke inhalation. This information would be of great interest for all emergency physicians since a proven or supposed cyanide poisoning does not only requires an intensive supportive care, including the administration of supplemental oxygen and artificial ventilation, blood pressure support, and anticonvulsants, but also a rapid administration of a cyanide antidote. Therefore, it is the goal of this survey to assess the prevalence of cyanide poisoning in smoke inhalation victims. Only the data of patients with a cyanide measurement before specific antidote treatment will be included

Our aim in this study is to investigate the efficiency of the breathing with different breathing patterns. Ten volunteers and twenty patients having respiratory problems will be coached on their breathing through specific masks which will provide four different breathing patterns. These patterns will be 1) Breathing in through the nose only and out through the mouth only 2) Breathing in through the mouth only and out through the nose only 3) Breathing in and out through the nose only 4) Breathing in and out through the mouth only The data obtained from volunteers and patients will be compared within and between the groups.
