Filter by:This research study will explore the effects of an online heart-focused breathing intervention on 20 informal caregivers of patients with Alzheimer's Disease (AD) over a period of two weeks.
The purpose of study is to determine effects of three different ET cuff pressure control on microaspiration of the stomach contents.
This trial examines the effects of filter ventilation on sensory response, smoking topography, and inhalation in current every day cigarette smokers. The physical design features of cigarettes directly impact their appeal by influencing cognitive and sensory perceptions. The introduction of a now common design feature, filter ventilation, has led to greater public harm than benefit because of the potential for greater toxicity while enhancing product appeal among smokers. Ventilated cigarettes dilute smoke, which promotes perceptions of ?smoothness? and therefore lower health risk, contributing to the overall appeal of these products. The purpose of this study is to assess whether removing ventilation from cigarette filters lowers cigarette product appeal among smokers.
The aim of the present study is to investigate the effects of additional functional inspiratory muscle training in individuals with non-specific chronic neck pain.
The aim of the research project is to evaluate the breathing effort using the Work of Breathing (WoB) and Pressure-Time Product (PTP) parameters, depending on the increasing flow resistance. The research project is concerned with assessing the increased (imposed) breathing effort using the Work of Breathing (iWoB) and the Pressure-Time Product (iPTP). The main hypothesis tested is the differential effect of flow resistance on iWoB and iPTP parameters in spontaneous breathing of healthy probands.
Pressure support ventilation allows intubated ICU patients to breathe spontaneously. Among specific settings, the adjustment of the trigger value (or threshold for triggering the ventilator) has not been explored to date. The trigger threshold corresponds to the sensitivity of the ventilator to detect patient's inspiratory effort and then deliver the predefined pressure support to inflate the lungs and deliver a tidal volume. The purpose of this study is to explore the influence of trigger level on pulmonary and ventilatory physio (-patho)logical parameters in spontaneously breathing ICU patients.
This study is aimed at evaluating patient work of breathing and tidal volumes with three methods of oxygenation: standard oxygen, high-flow oxygen therapy and non-invasive ventilation.
To correlate the data obtained by Electrical impedance tomography (EIT) during the spontaneous breathing trials (SBT) on a T-piece, in children, with failure in the trial and Extubation failure. Observe if the EIT monitoring will be able to detect the children that will fail earlier than the SBT performed alone. Method: A cross-sectional, prospective study to explore the potential benefits of monitoring with EIT during weaning.
Upper airway obstruction (UAO) is an unrecognized source of hemodynamic stress that may contribute to aortic adverse events in persons with Marfan Syndrome (MFS). UAO occurs during snoring and sleep apnea and is characterized by repetitive partial or complete obstruction of the upper airway during sleep. These obstructive breathing events lead to intermittent surges in blood pressure (BP) REF and large decreases in pleural pressure (Pes), thereby increasing the trans-mural aortic pressure (TMP) and imposing mechanical stress on the aorta during sleep. Although UAO is known to increase mechanical stress on the aorta, the magnitude of the increase is not known for persons with MFS. In this project, therefore, the investigators will also examine the changes in Pes and BP responses in periods of obstructed breathing and compare the diurnal markers or vascular stress between Baseline and CPAP studies in MFS persons.
The aim of the present investigation will be to evaluate diaphragmatic excursion velocity during non-invasive ventilation and spontaneous breathing at both inspiration and expiration. this analysis will be performed through diaphragmatic tissue Doppler assessment.
