Helmet interface for noninvasive ventilation

Several types of helmets are commercially available in Europe, each with different features. There are no helmets commercially available for use with NIV in the US, but one helmet is approved for use in bariatric chambers to protect against excessively high oxygen tensions. This graphic shows a representative image of helmet interface used to deliver noninvasive ventilation. Shown are ventilation ports for the administration and removal of gas flow and a rubber seal at the neck, while others have additional optional features including ports for the introduction of catheters and under-arm straps for extra security to ensure a tight seal.
