Helmet NIV in Acute Respiratory Failure

The helmet interface is a modality which is used to deliver NIV to patients with respiratory failure. A transparent hood is placed over the entire head of the patient with a seal at the neck using a soft collar.

The facemask interface is a modality which is also used to deliver NIV to patients with respiratory failure. A large mask covering the mouth and nose is strapped to the patient's face to create a seal.
