Background:
Noninvasive ventilation is mechanical respiratory support without the use of an artificial airway. There is no need for a tube or analgosedation. There are some advantages in comparison to invasive forms of ventilation.
Objectives:
Many patients are treated out of hospital because of acute dyspnea. For these patients, noninvasive ventilation is a therapeutic option. Some prehospital intubations can be avoided, if some kind of noninvasive ventilation is available.
Conclusions:
In order to offer noninvasive ventilation to all patients, it also has to be available in the prehospital setting. Modern mechanical ventilators, which are used in emergency medical service, are eligible to provide noninvasive ventilation.
