Filter by:Almost 50% of all children have at least 1 episode of noisy breathing before the age of 2 years and almost 25% of these children have more episodes of noisy breathing. The lack of an objective technique for diagnosing noisy breathing children often leads to overrated diagnosis of "wheezing", whereas there may be other noisy breathing phenotypes, like "rattling", that don't favor from the same therapeutic treatment. Presumably, different underlying pathophysiological mechanisms are involved with different biomarker profiles characteristic for different phenotypes. The goal of this study is to optimize the diagnosis of noisy breathing infants and toddlers. Children will be followed for a treatment period of 6 weeks and will visit the paediatrician 3 times (week 0, 3 and 6). During the consultations breath sound analysis will be performed and a breath sample and a nasal mucus will be collected to analyse biomarker profiles. Both methods for diagnosing noisy breathing infants are non-invasive and will be compared to the standard procedure of the paediatrician which consists of auscultation and palpation of the chest. An objective and non-invasive method for diagnosing noisy breathing infants and toddler will pave the way for more cost-effective and personalized prescription of therapies which will increase the quality of life of children with noisy breathing.
This study aims to assess the prevalence of sleep disorder breathing in pregnant women with a singleton gestation who develop hypertensive disorder of pregnancy (HDP) compared to women without HDP, when matched for gestational age and body mass index.
Central sleep apnea (CSA) is common in patients with heart failure and those using opioid analgesics. Unfortunately, effective treatment of central apnea remains elusive, pressure therapy given the modest efficiency of positive airway pressure therapy. The focus of this proposal is to identify mechanistic pathways to guide future therapeutic interventions for central sleep apnea based on the strong premise that multi-modality therapy will normalize respiration and hence mitigate adverse long-term consequences of CSA. The investigators' proposed studies will test combination therapies, including positive airway pressure (PAP) plus a pharmacological agent who have heart failure or are using opioid analgesics. The investigators anticipate that findings will inform future clinical trials to improve care and quality of life among Veterans suffering from central sleep apnea, which remains difficult to treat using existing approaches.
Prospective, single-arm, open label, multicentre, phase II pilot study to evaluate the immediate and short term (one month) impact of a new long acting double bronchodilator on innovative parameters in stable and moderate to severe COPD patients. - Variability and complexity of resting tidal breathing - Oscillatory resistance and reactance of airways Tidal volume variability and complexity is decreased in airway obstruction and is expected to improve with a bronchodilator treatment, together with lung mechanics. The relationship with changes in dyspnea and conventional pulmonary function tests is the second aim of study. After baseline assessment of these parameters, clinical and lung function evaluation will be performed 2 hours post-drug (peak drug effects). Patients will continue treatment with PT003 for 4 weeks. On Day 30, the same clinical and lung function assessments will be performed pre (trough) and 2h-post dose in order to obtain after-treatment measurements.
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.
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.
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.
This clinical trial is aimed to show a spontaneous breathing trial using high flow oxygen therapy may lower weaning failure rate and reintubation rate than using T-piece.
The purpose of the present study is to investigate the effectiveness of inspiratory muscle training and nasal high flow oxygen in patients with difficult weaning and high-risk for re-intubation. The hypothesis of the study is that starting inspiratory muscle training once patients are awake and co-operative along with the application of nasal high flow oxygen immediately after extubation will have a beneficial effect in preventive re-intubation in these high-risk patients.
