Active clinical trials for "Respiratory Aspiration"

The purpose of this study is to test the use of Calypso beacon implants as a way to determine where the lung tumor is located during radiation treatment. The Calypso beacons are small devices that are implanted in the lungs, near the tumor. They are able to send a signal to a tracking system to show where they are, and where the tumor is, as the patient holds their breath for the radiation treatment. The investigators want to find out what effects, good and/or bad, that this has on the patient and the way they treat the cancer in your lungs.

This pilot study is part of a phased approach to refine, optimize, and test the feasibility of CALM Breathing. Preliminary participant feedback from the Capnography-Assisted Respiratory Therapy (CART) study was applied to adapt and design CALM Breathing (including its dose, schedule, delivery, and home program). This pilot builds on initial lessons learned and identifies intervention areas still needing greater development to assure the success of a future large trial, targeting a subpopulation at risk, that is, those with COPD and anxiety sensitivity.

Preliminary reports have been received from several sources that the periodic inhaling of the nebulized mist from water that has a heightened level of kinetic activity has quickly (less than 2 days) lessened the severity of symptoms in Covid-19 infected patients. On at least several occasions, a repeat PCR test performed several after inhaling a particular water-based product was negative. There are no perceived adverse effects from inhaling the water mist by using a nebulizer or humidifier. It is important, however, to validate these preliminary findings and to include the inhaling of the mist from water, which does not have an elevated level of kinetic activity. This will be by performed in a patient-blinded manner by sequentially inhaling the two types of water over consecutive 2-day periods with Covid-19 testing at the end of each of the two day periods. Participants will be randomized as to whether they are to inhale the mist from the test or the control water.

This study compares the diagnostic capability of a millimeter-wave radar-based Sleep Respiratory Monitoring System to the gold standard polysomnography.

The presence of solid food or fluid residue in the stomach is always a major concern when patients require medical procedures under sedation or general anesthesia, due to the high risk of pulmonary aspiration of the stomach contents. This is especially important in emergency procedures, when a fasting period could not be observed. Pulmonary aspiration of gastric content is a serious perioperative complication of obstetric anesthesia, and it is associated with morbidity and mortality. Information from a bedside ultrasound assessment of the stomach may be a very useful resource to decide whether it's safe to proceed, cancel or delay a surgical procedure. The ultrasound assessment of the stomach content has shown to be very feasible and practical in non-pregnant patients. However, it has not been determined whether the competence reached by anesthesiologists in non-pregnant subjects can be transferred to the obstetric population, especially in term pregnant patients where it could be difficult to identify the stomach because of the presence of the gravid uterus. Although quantitative assessment of the gastric antrum cross-sectional area in terms of intra- and interrater reliability has been evaluated in non-pregnant adults, it remains to be evaluated in pregnant patients. Furthermore, it has not been determined whether the performance of novice operators is comparable to expert operators in the gastric quantitative assessment. This study aims to determine whether trained anesthesiologists can reliably assess the stomach content of pregnant patients by ultrasound, evaluating the inter- and intra-rater reliability of quantitative gastric ultrasound in term pregnant patients comparing anesthesiologists of different level of expertise. The investigators hypothesize a substantial to almost perfect agreement in the intra- and interrater reliability of the antral cross-sectional area among raters in term pregnant patients scheduled for elective cesarean delivery.

Weaning is an important process to gradually separate mechanically ventilated patients from ventilators. A good weaning strategy aims to early identify mechanically ventilated patients who are ready for extubation but not to prematurely extubate them. Spontaneous breathing trial (SBT) is a test to assess the patient's ability to breathe spontaneously when extubated. Several methods have been used to conduct an SBT, including T-piece breathing, low-level pressure support ventilation (PSV) of 5-7 cm H2O, continuous positive airway pressure and automatic tube compensation (ATC). The investigators hypothesized that an SBT with inspiratory pressure augmentation increases initial SBT success, reduces the length of invasive mechanical ventilation (iMV) support and does not increase reintubation risk as compared with T-piece, which result in a higher proportion of patients successfully liberated from iMV in the inspiratory pressure augmentation group. However, inspiratory pressure augmentation significantly reduces work of breathing on an SBT as compared with T-piece. Patients extubated following an SBT with inspiratory pressure augmentation may experience increased respiratory effort after extubation and this may increase the use of noninvasive ventilation after extubation. An SBT with inspiratory pressure augmentation increases iMV free days but not MV free days as compared with T-piece. Longer iMV free days may be associated with a lower mortality due to fewer iMV related complication. This study is a pragmatic, cluster-randomized, multiple crossover, multicenter trial to compare SBTs with T-piece versus inspiratory pressure augmentation in weaning outcomes. Mechanically ventilated patients who meet the criteria for readiness to SBT will be included. The patients will use either T-piece or inspiratory pressure augmentation as SBT for weaning according to an ICU-based cluster randomization and crossover sequence.

It was planned to examine the effects of breathing exercises applied with virtual reality glasses on dyspnea, anxiety and quality of life in COPD patients. The study was planned to be conducted in a single-blind pre-test post-test parallel group randomized controlled experimental design. Hypotheses created for the research; H0a: There is no difference between the dyspnea scores of the experimental group and the control group in the post-test in COPD patients. H0b: There is no difference between the anxiety scores of the experimental group and the control group in the post-test in COPD patients. H0c: There is no difference between the quality of life scores of the experimental group and the control group in the post-test in COPD patients. H1a: There is a difference between the dyspnea scores of the experimental group and the control group in the post-test in COPD patients. H1b: There is a difference between the anxiety scores of the experimental group and the control group in the post-test in COPD patients. H1c: There is a difference in quality of life scores between the experimental group and the control group in the post-test in COPD patients. It is planned to apply breathing exercise through virtual reality glasses for 8 weeks to the experimental group. It is planned that the exercises will be done three times a week in a total of 24 sessions. No intervention will be applied to the control group. It is planned to collect the research data in the pre-test, four weeks after the pre-assessment, and in the post-test (in the eighth week of the study). Inclusion criteria for the study; Being over 18 years old, being GOLD Stage II-III COPD (FEV1/FVC<70%, FEV1<80%), being >24 as a result of the mini mental state assessment test, residing in the city center where the research was conducted. Exclusion criteria; exacerbation of COPD for the last four weeks, pneumonia, use of psychiatric medication.

This research will aid in understanding of slow-breathing and its effect on heart rate and blood pressure in people with a spinal cord injury (SCI). This research will investigate if traditional 'yogic' breathing exercises can be performed by subjects with SCI and its influence on the cardiovascular system.
