The purpose of the study is to determine the frequency and management of respiratory incidence in patients with invasive out-of-hospital ventilation, either living at home for elderly people allay to a weaning centre or at home. Further, the mortality and the frequency of hospital admission will be analyzed.

Background: There has been arise in a number of patients requiring long term ventilation both in the in-hospital as well as the out-of-hospital setting. Despite this, little is known about the subsequent political course of this patients following hospital discharge.

Interventions: This is an observational prospective study over a period of one year in a sample of 50 to 70 invasively ventilated patients living either in a nursing home specialized in the care of ventilated patients or at home. Protocol had been developed containing 20 suspected emergency incidences in respiratory care. The nursing staffs are instructed about the study and how to complete the protocol. The protocol was placed at each patient and every time an emergency occurred, the nursing staff registered the incidence. If an emergency fulfils more than one criterion in the protocol, every applicable criterion was marked. The data will be analyzed using non-parametric descriptive statistics.
