Active clinical trials for "Respiratory Aspiration"

This non-randomised open-label prospective pilot study evaluates the safety and efficacy of inhalations of ultra-low doses of alkylating drug melphalan for the treatment of non-cystic fibrosis bronchiectasis. All patients will receive 0,1 mg of melphalan in 5 daily inhalations 1 time per day.

A clinical trial will be carried out in the area of physiotherapy and rehabilitation of the "Centro Integral de Rehabilitación S.C. at the Hospital Angeles Lomas" in Mexico. Which, will have 3 arms (1. New intervention protocol created by the main author in the use of the inspirometer, 2. Conventional use of the inspirometer, 3. breathing exercises without the use of inspirometer) with hospitalized patient population and whose purpose will be to determine the effectiveness of the new intervention protocol and compare it with the current protocol and respiratory exercises.

The aim of this randomized controlled trial study was to assess the effects of an 4-week exercise program on the recovery capacity after a voluntary maximal apnea. Participants will be randomly allocated to perform an experimental breathing protocol (NR-HB), or an usual training using their usual breathing (UB) protocol.

Inspiratory muscle training has been an important part of pulmonary rehabilitation program directed at patients with COPD. It can increase respiratory muscle strength, relieve dyspnea ,improve the quality of life in COPD patients. However, there is no uniform standard for the intensity of inspiratory muscle training. By comparing a series of indexes, such as maximal inspiratory pressure, maximal expiratory pressure, degree of dyspnea and exercise capacity before and after the training under different intensity, a large number of literatures have explored the appropriate intensity of inspiratory muscle training. But to date, there are few studies about the effects of different intensity of inspiratory muscle training on respiratory physiological mechanism. It has been shown that inspiratory muscle training may be more beneficial to improve the pulmonary rehabilitation effect of COPD patients with inspiratory muscle weakness. So it is not clear whether there is a difference in respiratory physiology between patients with normal inspiratory muscle strength and those with lower inspiratory muscle strength. Respiratory central drive, as an important physiological index, which can be reflected by minute ventilation volume, mouth pressure, mean inspiratory flow and diaphragm electromyography,is closely related to the symptoms and the severity of the disease.Therefore,the purpose of this study was to investigate the changes of respiratory mechanics and central drive in COPD patients at different inspiratory loads, and at the same loads between patients with and without respiratory muscle weakness.That can provide more evidential evidence for setting up the intensity of inspiratory muscle training.

Obstructive sleep apnea syndrome (OSAS) is defined as a total cessation of upper airway flow for at least 10 seconds. OSAS is considered under diagnosed and it is assessed by a full-night sleep polysomnography. Continuous positive airway pressure (CPAP) is considered the first line treatment to OSAS, however physical exercise has emerged as an adjunct and/or alternative strategy to CPAP in OSAS patients.

Comparing the effects of different kinds of aerosol inhalation nursing programs on effective sputum excretion in elderly patients with lung surgery.

The purpose of this investigation is to obtain more information on the efficacy and safety of respiratory training methods with WellO2 in patients with asthma and COPD. Such a training may offer an additional, non-pharmacological way for treatment and therapy of asthma and COPD.

The purpose of this study is evaluate the effect the inspiratory muscle training on the functional capacity of patients with pulmonary hypertension.

Nitro Oxide (NO) inhalation was recognized as an effect treatment of Neonatal Persistent Pulmonary Hypertension (PPHN), while the safety of NO long term application was under investigation. Several research suggested too much NO2 was generated in the lung after long term (> 72h) use of NO inhalation, which cause bad effects on PS production. Sildenafil was proved to be effective to PPHN as NO. This medication has a similar clinical effect but need monitoring of blood pressure. The possible hypotension effect restrict the dosage of sildenafil, which limit the usage of sildenafil in severe PPHN. But we recommend sildenafil to The purpose of the study was to establish if NO continued with sildenafil has the same effect as single NO inhalation.

This study will assess in a double blind placebo controlled fashion the effects of a 12 week course of oral montelukast/placebo on polysomnographic and radiological findings and will characterize the systemic (serum,urine) and local (upper airway collected biological samples) inflammatory response in children (2-10 years of age) with sleep disordered breathing, fittingthe inclusion and exclusion criteria.
