Clinical Trial Summary

Non-invasive ventilation (NIV) is a form of respiratory support that has been shown to prevent invasive mechanical ventilation and reduce mortality. This study will investigate the feasibility of performing a larger study examining whether a new modality of NIV, the helmet, is superior to the current face mask in reducing mortality in patients with sudden respiratory failure.

Eligibility

Inclusion Criteria:

• 1) patients who are admitted to the adult ICU

• 2) deemed to require NIV, as per the clinical team, for acute respiratory failure.

Exclusion Criteria:

• 1) with impending cardiac arrest or need for intubation

• 2) Glasgow coma scale <9

• 3) tracheostomy or upper airway obstruction

• 4) elevated intracranial pressure

• 5) untreated pneumothorax

• 6) who refuse endotracheal intubation (do not intubate order documented)

• 7) facial trauma

• 8) are unable to wear the helmet or facemask

• 9) who use NIV chronically

Related Conditions & MeSH terms

• Respiratory Distress Syndrome
• Respiratory Insufficiency

Intervention

Device:
• Helmet Non-Invasive Ventilation
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.
• Facemask Non-Invasive Ventilation
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.
