Moving from Inpatient to Outpatient or Home Initiation of Non-Invasive Home Mechanical Ventilation.

Home mechanical ventilation (HMV) is an effective treatment for patients with chronic hypercapnic respiratory failure caused by restrictive or obstructive pulmonary disorders. Traditionally, HMV is initiated in the hospital, nowadays usually on a pulmonary ward. The success of HMV, and especially non-invasive home mechanical ventilation (NIV), has led to a steep and ongoing increase in the incidence and prevalence of HMV, in particular for patients with COPD or obesity hypoventilation syndrome.

Patient-Ventilator Synchronization During Non-invasive Ventilation: A Pilot Study of an Automated Analysis System.

Patient-ventilator synchronization during non-invasive ventilation (NIV) can be assessed by visual inspection of flow and pressure waveforms but it remains time consuming and there is a large inter-rater variability, even among expert physicians. SyncSmart™ software developed by Breas Medical (Mölnycke, Sweden) provides an automatic detection and scoring of patient-ventilator asynchrony to help physicians in their daily clinical practice. This study was designed to assess performance of the automatic scoring by the SyncSmart software using expert clinicians as a reference in patient with chronic respiratory failure receiving NIV.

[Withdrawal of chronic mechanical ventilation at home: coordination, organisation and implementation].

In the Netherlands, an increasing number of patients are dependent on domiciliary ventilation. General practitioners and elderly care physicians caring for these patients are increasingly confronted with problems related to chronic ventilation. Most patients die due to progression of respiratory failure, however, patients may ask their physician to electively withdraw their assisted ventilation.

Airway clearance techniques in neuromuscular disorders: A state of the art review.

This is a unique state of the art review written by a group of 21 international recognized experts in the field that gathered during a meeting organized by the European Neuromuscular Centre (ENMC) in Naarden, March 2017. It systematically reports the entire evidence base for airway clearance techniques (ACTs) in both adults and children with neuromuscular disorders (NMD). We not only report randomised controlled trials, which in other systematic reviews conclude that there is a lack of evidence base to give an opinion, but also include case series and retrospective reviews of practice.

The frontotemporal syndrome of ALS is associated with poor survival.

Thirty percent of ALS patients have a frontotemporal syndrome (FS), defined as behavioral changes or cognitive impairment. Despite previous studies, there are no firm conclusions on the effect of the FS on survival and the use of non-invasive ventilation (NIV) in ALS. We examined the effect of the FS on survival and the start and duration of NIV in ALS.

Hot Topics in Noninvasive Ventilation: Report of a Working Group at the International Symposium on Sleep-Disordered Breathing in Leuven, Belgium.

During the last few decades, attention has increasingly focused on noninvasive ventilation (NIV) in the treatment of chronic respiratory failure. The University of Leuven and the University Hospitals Leuven therefore chose this topic for a 2-day working group session during their International Symposium on Sleep-Disordered Breathing. Numerous European experts took part in this session and discussed (1) NIV in amyotrophic lateral sclerosis (when to start NIV, NIV and sleep, secretion management, and what to do when NIV fails), (2) recent insights in NIV and COPD (high-intensity NIV, NIV in addition to exercise training, and NIV during exercise training), (3) monitoring of NIV (monitoring devices, built-in ventilator software, leaks, and asynchronies) and identifying events during NIV; and (4) recent and future developments in NIV (target-volume NIV, electromyography-triggered NIV, and autoregulating algorithms).

Quality of life of adult men with Duchenne muscular dystrophy in the Netherlands: implications for care.

Objective: To assess quality of life of adults with Duchenne muscular dystrophy in the Netherlands and to identify domains and major problems influencing quality of life.

Design: Cross-sectional.

Subjects: Seventy-nine men aged ≥ 20 years with Duchenne muscular dystrophy.

[Terminal care in patients with amyotrophic lateral sclerosis].

Patients with amyotrophic lateral sclerosis (ALS) often fear of dying from suffocation. This fear is also common in relatives and caregivers. Research has, however, shown that ALS patients seldom die from suffocation.

Pneumothorax as a complication of lung volume recruitment.

Lung volume recruitment involves deep inflation techniques to achieve maximum insufflation capacity in patients with respiratory muscle weakness, in order to increase peak cough flow, thus helping to maintain airway patency and improve ventilation. One of these techniques is air stacking, in which a manual resuscitator is used in order to inflate the lungs. Although intrathoracic pressures can rise considerably, there have been no reports of respiratory complications due to air stacking.

[Non-invasive home mechanical ventilation: qualification, initiation, and monitoring].

Following the introduction of non-invasive positive pressure ventilation (NPPV), the number of patients using home mechanical ventilation has increased substantially and continues to rise worldwide. This is primarily explained by both the effectiveness and comfort that are offered by NPPV in most patients, and particularly in patients with chest wall and neuromuscular diseases. For clinically stable patients the qualification for NPPV largely depends on the presence of complaints or signs of (nocturnal) hypoventilation with accompanying hypercapnia.

Thirty years of home mechanical ventilation in children: escalating need for pediatric intensive care beds.

Purpose: To describe trends in pediatric home mechanical ventilation (HMV) and their impact on the use of pediatric intensive care unit (PICU) beds.

Methods: Review of all children who had started HMV in a single center for HMV.

Results: Between 1979 and 2009, HMV was started in 197 patients [100 (51%) with invasive and 97 with noninvasive ventilation], with a median age of 14.

[Home mechanical ventilation in the Netherlands].

Over the last 20 years the number of Dutch patients on home mechanical ventilation has increased from 200 to 2000. Home mechanical ventilation is a cost-effective treatment which significantly improves the quality of life of patients. In 2011 83% of patients on home mechanical ventilation in the Netherlands is living at home.

[Lung volume recruitment in impending respiratory failure].

Lung volume recruitment can improve peak cough flows and respiratory compliance in patients who either do or do not require mechanical ventilation. There are several lung volume recruitment techniques: air stacking, glossopharyngeal breathing and mechanical insufflation-exsufflation with cough assist devices. The principle of lung volume recruitment is based on the insufflation of air in the lungs after maximal inspiration.

[Obesity hypoventilation syndrome--serious but reversible providing weight is lost].

Obesity hypoventilation syndrome (OHS) is a condition in which obesity and chronic hypoventilation during waking hours are combined. Patients with OHS are more likely to be hospitalized and to require intensive-care monitoring compared with patients with similar degrees of obesity without hypoventilation. Treatment with chronic non-invasive positive pressure ventilation (NPPV) is associated with a lower morbidity and mortality.
