Microbiologic Contamination of Home Non Invasive Ventilators

Microbiologic Contamination of Home Non Invasive Ventilators

Home non-invasive ventilators are daily used by patients with chronic respiratory failure. There are frequently used with warming and humidifying systems. These systems need to be cared for and frequently washed by the patient.

The aim of this study is to evaluate if the humidifying system of home ventilators are colonized by microbiological germs.

The use of non-invasive ventilators is common for treating respiratory failure. Their care relies on the patients and their carers.

No study has assessed the efficacy of such care with respect to the number of microbiological specimens that remain in the humidifier.

Inclusion Criteria:

• Patient established on home non invasive ventilation for more than 6 months

Exclusion Criteria:
