BACKGROUND: On initiation of long-term non-invasive ventilation (NIV), intermittent upper airway obstruction has rarely been described as possibly treatment-induced. Inspiratory pressure effects and the use of an oronasal interface may promote obstructive events in some patients with neuromuscular disease (NMD) and amyotrophic lateral sclerosis (ALS) in particular. METHODS: We evaluated clinical data from 212 patients in whom NIV was initiated using an oronasal mask...

Background: Chronic hypercapnic respiratory failure (HRF) in obesity hypoventilation syndrome (OHS) is commonly treated using non-invasive ventilation (NIV). We hypothesised that treatment of OHS would improve neural respiratory drive index (NRDI) and cardiac function. Methods: Fourteen patients (8 females) with OHS, who were admitted for initiation of domiciliary NIV, were prospectively studied. Patients had (mean ± SD): age (53±10 years), body mass index (BMI) (50...

Motor neurone disease (MND) is a neurodegenerative disease defined by axonal loss and gliosis of upper and lower motor neurones in the motor cortex, lower brainstem nuclei and ventral horn of the spinal cord. MND is currently incurable and has a poor prognosis, with death typically occurring 3 to 5 years after disease onset. The disease is characterised by rapidly progressive weakness leading to paralysis, fasciculations, bulbar symptoms (including dysarthria and dysphagia) and respiratory compromise. Respiratory complications arise as a result of weakness of upper airway (pharyngeal and laryngeal) muscles and respiratory muscles (diaphragm, intercostal and accessory muscles) leading to respiratory failure...

Patient-ventilator asynchrony (PVA) are a common phenomenon affecting all patients receiving long-term domiciliary ventilation. The interruption of synchrony between the patient and the ventilator has been reported to be a possible cause of nocturnal sleep disruption leaking to arousals, awakenings and reduced periods of stage 3 and REM sleep overnight. The cause of PVA is multi-factorial driven frequently by leak at the interface, changing respiratory breathing patterns and changes in sleep stages. It currently remains unclear as to whether the PVA is the cause of sleep fragmentation or if PVA is purely a marker of unsuccessful ventilatory control, patient discomfort and underlying sleep disruption...

Chronic obstructive pulmonary disease (COPD) remains a common cause of morbidity and mortality worldwide. Patients with COPD and respiratory failure, whether acute or chronic have a poorer prognosis than patients without respiratory failure. Non-invasive ventilation (NIV) has been shown to be a useful tool in both the acute hospital and chronic home care setting. NIV has been well established as the gold standard therapy for acute decompensated respiratory failure complicating an acute exacerbation of COPD with reduced mortality and intubation rates compared to standard therapy...

Background: Limited therapeutic options are available for Fontan patients with dysfunctional or failing single ventricle physiology. This study describes the evaluation of an alternative, non-invasive, at-home therapeutic compression treatment for Fontan patients. Our hypothesis is that routinely administered, externally applied compression treatments to the lower extremities will augment systemic venous return, improve ventricular preload, and thus enhance cardiac output in Fontan patients...

Objective A severely altered level of consciousness (ALC) is considered to be a possible contraindication to non-invasive ventilation (NIV). We investigated the association between mild ALC and NIV failure in patients with hypoxemic respiratory failure. Methods A retrospective study was conducted by reviewing the medical charts of patients with de novo hypoxemic respiratory failure who received NIV treatment. The clinical background and the outcomes of patients with and without ALC were compared. Patients or Materials Patients who were admitted to our hospital for acute hypoxemic respiratory failure between July 2011 and May 2015 were included in the present study...

Acute and chronic respiratory failures require immediate diagnosis and preferably individualized ventilation therapy. If possible, non-invasive ventilation should be considered to avoid complications of invasive mechanical ventilation. Especially in patients with ARDS and moderate to severe cases, non-invasive ventilation may not be suitable and should not be used uncritically.Invasive mechanical ventilation parameters should be adjusted individually. In the future, additional parameters such as transpulmonary pressure, monitoring of regional ventilation using electrical impedance tomography could help to individualize ventilator settings...

The term "respiratory insufficiency" (RI) describes the inability of an organism to maintain the gas exchange between the ambient air and its peripheral organs. This causes a hypoxia and hypercapnia. The mechanisms that lead to RI are either an impaired gas exchange in the lung tissue or an alveolar hypoventilation caused by an insufficient ventilatory pump. Thus the RI is divided into a hypoxic or a hypercapnic RI. The diagnostic procedure for RI contains several examinations. One key aspect of the exploration is the identification of potential reversible and thus correctable reasons of the RI...

Recently, it has been clearly described an independent relationship between obstructive sleep apnea syndrome (OSAS) and cardiovascular risk, with underlying mechanisms also including endothelial dysfunction. We enrolled 32 consecutive non-obese patients (mean age of 39.5±11.5 years), of which 16 with mild OSAS and 16 snoring without OSAS. Mild OSAS is defined by an AHI index between 5 and 15. We have investigated if whether there was a relationship between mild OSAS, endothelial function and carotid intima-media thickness (C-IMT)...

Technologies for minimally-invasive cardiac output measurement in patients during surgery remain little used in routine practice. We tested a redeveloped system based on CO 2 elimination (VCO 2 ) by the lungs for use in ventilated patients, which can be seamlessly integrated into a modern anesthesia/monitoring platform, and provides automated, continuous breath-by-breath cardiac output monitoring. A prototype measurement system was constructed to measure VCO 2 and end-tidal CO 2 concentration with each breath...

Spinocerebellar ataxia type 1 (SCA1) is characterized by adult-onset cerebellar degeneration with attendant loss of motor coordination. Bulbar function is eventually impaired, and patients tend to die from inability to clear the airway. We asked whether motor neuron degeneration is at the root of bulbar dysfunction by studying SCA1 knock-in mice. We analyzed spinal cord and brainstem motor neurons in SCA1 knock-in (Atxn1154Q) mice at 1, 3, and 6 months of age. Specifically, we assessed breathing physiology, diaphragm histology and electromyography, and motor neuron histology and immunohistochemistry...

Treating respiratory distress is a priority when managing critically ill patients. Non-invasive ventilation (NIV) is increasingly used as a tool to prevent endotracheal intubation. Providing oral or enteral nutritional support during NIV may be perceived as unsafe because of the possible risk of aspiration so that these patients are frequently denied adequate caloric and protein intake. Newly available therapies, such as high-flow nasal oxygen (HFNO) may allow for more appropriate oral feeding.

BACKGROUND: Previous data showed that non-invasive ventilation (NIV) applied for 3 min before tracheal intubation ensured better oxygenation compared with using a non-rebreather bag-valve-mask. We aimed to determine whether preoxygenation using NIV is effective in reducing the incidence of organ dysfunction in hypoxaemic, critically ill patients in intensive care. METHODS: A multicentre, randomised, open-label trial evaluating 100% FiO 2 administered with NIV (99 patients) vs with face mask (102 patients) for 3 min before tracheal intubation...

BACKGROUND: Pneumonia is a preventable cause of mortality in children. Streptococcus pneumoniae colonising the nasopharynx of healthy children can cause invasive diseases and the serotype distribution of colonisation isolates should be an indicator of invasive disease, antibiotic resistance profiles, and potential vaccine coverage. Identifying factors influencing nasopharyngeal colonisation, the serotypes and antimicrobial resistance pattern can improve rational preventive strategies...
