[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.

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.

[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.
