BACKGROUND: Reintubation is associated with high mortality. Identification of methods to avoid reintubation is needed. The aim of this study was to assess whether prophylactic noninvasive ventilation (NIV) would benefit patients with various cough strengths. METHODS: We prospectively enrolled 356 patients who successfully passed a spontaneous breathing trial in a respiratory intensive care unit. Before extubation, cough peak flow was measured. After extubation, attending physicians determined whether the patients would receive prophylactic NIV or conventional oxygen treatment (control group)...

INTRODUCTION: Respiratory muscle training is the most commonly used method to revert respiratory muscle weakness; however, the effect of protocols based on non-respiratory maneuvers has not been adequately studied in the pediatric population. The objective of this study was to establish the effect of abdominal muscle training on respiratory muscle strength and forced expiratory flows in healthy adolescents. METHODS: This was a quasi-experiment. The sample was made up of healthy adolescents divided into two groups: an experimental group who completed eight weeks of active abdominal muscle training, and an equivalent control group...

PURPOSE: To assess the ability of a mechanical in-exsufflator (MI-E), either alone or in combination with manual thrust, to augment cough in patients with neuromuscular disease (NMD) and respiratory muscle dysfunction. MATERIALS AND METHODS: For this randomized crossover single-center controlled trial, patients with noninvasive ventilator-dependent NMD were recruited. The primary outcome was peak cough flow (PCF), which was measured in each patient after a cough that was unassisted, manually assisted following a maximum insufflation capacity (MIC) maneuver, assisted by MI-E, or assisted by manual thrust plus MI-E...

BACKGROUND: Stepping down from combination asthma therapy (inhaled corticosteroids (ICS) + long-acting β2 agonists (LABA)) is often avoided due to fear of exacerbations, which may lead to overmedication in well-controlled asthma. A better knowledge about the predictors of outcome might encourage clinicians to start stepping down more often than previously. METHODS: In 55 subjects with well controlled asthma and combination therapy, LABAs were discontinued first, followed by ICS dose halving, and then cessation, in six weeks' intervals...

BACKGROUND: Noninvasive ventilation (NIV) is commonly used to provide ventilatory support for individuals with amyotrophic lateral sclerosis (ALS). Once 24-h ventilation is required, the decision between invasive tracheostomy ventilation and palliation is often faced. This study describes the use and outcomes of daytime mouthpiece ventilation added to nighttime mask ventilation for continuous NIV in subjects with ALS as an effective alternative. METHODS: This was a retrospective study of 39 subjects with ALS using daytime mouthpiece ventilation over a 17-y period...

BACKGROUND AND OBJECTIVE: Inherited neuromuscular disorders (NMD) inevitably result in severe lung volume restriction and cough insufficiency associated with high morbidity and mortality. The aim of this retrospective study was to evaluate whether the airways of patients with NMD are colonized with potential pathogenic microorganisms that might contribute to the pulmonary morbidity in NMD. METHODS: In this cross-sectional study, cough swabs were obtained and cultured for microbiological analyses from 77 patients with NMD and different degrees of lung volume restriction and cough insufficiency...

BACKGROUND: Mechanically assisted coughing with mechanical in-exsufflation (MI-E) is recommended for noninvasive management of respiratory secretions in amyotrophic lateral sclerosis (ALS). To improve the effectiveness of the technique, a new device combining MI-E with high-frequency oscillations (HFO) has been developed. This work aimed to assess the effect of HFO on the cough peak flow generated by MI-E in medically stable subjects with ALS. METHODS: This was a prospective study that included subjects with ALS in a medically stable condition...

Previous time series or panel studies of asthmatics have reported respiratory health effects following short-term exposure to ozone (O3). We followed 186 children aged 10 years old in Athens and Thessaloniki, Greece for 5 weeks during the academic year 2013-2014 and recorded daily their respiratory symptoms, absenteeism and peak expiratory flow (PEF). We applied mixed models controlling for various possible confounders to investigate the daily associations between O3 exposure - derived from weekly personal and fixed school site measurements calibrated using daily values of the fixed monitoring site nearest to the child's school location - and PEF, presence of any symptom, cough and stuffy nose, as well as absenteeism...

BACKGROUND AND PURPOSE: Respiratory insufficiency is the primary cause of morbidity and mortality in individuals with amyotrophic lateral sclerosis (ALS). Although mechanical interventions are effective in prolonging survival through respiratory support, pulmonary physical therapy interventions are being investigated. The purpose of this systematic review was to examine the effectiveness of pulmonary physical therapy interventions across the progressive stages of ALS. METHODS: Six databases were searched for articles from inception to December 2014 investigating pulmonary physical therapy interventions in the ALS population...

Rationale and key points The decision to remove an endotracheal tube (extubation) is taken when the patient achieves adequate airway control. This requires an effective cough and an acceptable level of consciousness. Practitioners should be able to identify when a patient is ready for endotracheal tube removal and to recognise contraindications and potential complications. ▶ The Glasgow Coma Scale should be used to assess the patient's level of consciousness. Extubation should not be performed on patients with a score of 8 or less...

This study examined the relationships between subjective descriptors and objective airflow measures of cough. We hypothesized that coughs with specific airflow characteristics would share common subjective perceptual descriptions. Thirty clinicians (speech-language pathologists, otolaryngologists, and neurologists) perceptually evaluated ten cough audio samples with specific airflow characteristics determined by peak expiratory flow rate, cough expired volume, cough duration, and number of coughs in the cough epoch...

INTRODUCTION: Late-onset Pompe disease (LOPD) is characterized by progressive skeletal and respiratory muscle weakness. Little is known about the effect of inspiratory muscle training (IMT) on pulmonary function in subjects with LOPD. The aim of the present study was to investigate the effect of an 8-week IMT program on pulmonary function tests, quality of life, and sleep quality in eight patients with LOPD who were receiving enzyme replacement therapy (ERT). METHODS: Before and after the IMT program, spirometric measurements in sitting and supine positions, and measurements of maximum inspiratory and expiratory pressures, peak cough flow, quality of life (assessed using the Nottingham Health Profile), and sleep quality (assessed using the Pittsburgh sleep quality index) were performed...
