Filter by:Ventilator hyperinflation (VHI) has been shown to be effective in improving respiratory mechanics, secretion removal, and gas exchange in mechanically ventilated patients; however, the literature is scarce concerning its safety and adverse effects. Thus, the aim of this study is to compare the hemodynamic repercussions of VHI in volume-controlled mode. In a randomized, controlled and crossover design, 24 mechanically ventilated patients will undergo 2 modes of ventilator hyperinflation (with and without an inspiratory pause) and a control intervention. Cardiac output, cardiac index, mean arterial pressure, pulmonary vascular resistance, systolic volume and other hemodynamic variables will be recorded during the interventions.
This trial will evaluate the effect of acetazolamide (375 mg per day) vs. placebo on lung water content by ultrasound at acute altitude exposure in patients with Chronic Obstructive Pulmonary Disease (COPD).
This study is a prospective observational study which aim to evaluate the feasibility of a total and systematic home respiratory rehabilitation training program in patients who will undergo thoracic surgery, and otherwise tend to define failure reasons.
Obstructive airways disease is the most common group of acute illnesses leading to hospital treatment in children. This group consists of different age-related diagnoses, such as bronchiolitis in infants or wheezing and asthma in older children. Though these entities overlap with each other, they have common characteristics and the same leading symptom breathing distress. The investigators aim conduct an observational cohort study to examine if the clinical course of respiratory distress be quantified and the treatment improved in children with acute breathing difficulty using a new non-touch non-invasive SLP measurement device? Thora3Di is a new CE- and FDA-approved medical device able to measure chest and abdominal wall movements during tidal breathing with a method called structured light plethysmography (SLP). The method is non-touch and non- invasive, it does not need any connection with the child. One-month- to 12-years-old infants and children are recruited from the paediatric wards at Evelina London Children's hospital. The child lies or sits within the field of vision of the SLP device with their chest and abdomen exposed. A grid pattern of normal light will be projected onto the chest and changes in the format of the grid as the infant or child breathes will be recorded by the SLP device. Data will be collected for each child for 3-5 minutes once in 24 hour periods for 2-10 times during hospital stay. The aim is to reduce duration of hospital stay by finding predicting parameters for obstructive airways diseases with the new SLP method, and further aim to standardization of treatment strategies, to reduce expenditure.
Although there has been some progress in pharmacological management of PAH, limited functional capacity and low survival still persist, but there is evidence that exercise training can be accomplished without adverse effects or damage to cardiac function and pulmonary hemodynamics. Specifically, improvements in symptoms, exercise capacity, peripheral muscle function and quality of life. Training programs need to be better studied and well defined, and their physiological effects during physical training and functional capacity. The aim of this study is to compare the effects of different training exercises on physical performance indicators.
This study aims to evaluate the presence of lung function impairment in a sample of patients diagnosed with non-affective psychosis.
The aim of this study is to assess the effectiveness of a home-based exercise training program in COPD patients who have completed a pulmonary rehabilitation.
A retrospective cohort study of all patients treated for type II (hypercapnic) respiratory failure with either High-Flow Oxygen Therapy or Non-Invasive Ventilation in a general adult hospital.
The purpose of this study is to test two different vaccine schedules to be used for administering the investigational NTHi Mcat vaccine that will be targeting patients with chronic obstructive pulmonary disease (COPD) to prevent acute exacerbations. An acute exacerbation is when the breathlessness in COPD patients will get even worse than it normally already is, sometimes to the point where oxygen therapy is required. In previous studies, study participants have received two doses of the vaccine according to a 0, 2 month vaccination schedule, in addition to standard care. The current study will find out if a third dose of the study vaccine against NTHi/Mcat is safe and working well. The study will also investigate if the third dose of vaccine works best when given after 6 months or after 12 months.
The purpose of the study is to determine whether patients who use a prompt sheet to identify their important issues before they see a doctor are more likely to feel that their important issues have been discussed during their consultation. The study will be conducted in a respiratory outpatient clinic.
