Unusual applications of noninvasive ventilation

Area of Science:

• Pulmonology
• Critical Care Medicine

Background:

• Noninvasive ventilation (NIV) is widely used for acute hypercapnic respiratory failure, cardiogenic pulmonary edema, ARDS, pneumonia, and post-extubation failure.
• Its application in less common clinical scenarios is gaining attention.

Purpose of the Study:

• To review the evidence and clinical utility of NIV in unusual conditions.
• To highlight specific applications and contraindications for NIV.

Main Methods:

• Literature review of studies investigating NIV use in diverse clinical settings.
• Analysis of evidence supporting NIV in specific procedures and patient groups.

Main Results:

• NIV is supported during fiberoptic bronchoscopy, especially for high-risk patients.
• NIV can reduce sedation needs in procedures like transesophageal echocardiography and interventional cardiology/pulmonology.
• Evidence suggests NIV utility post-cardiac surgery and in pulmonary contusion, though with lower certainty.
• NIV is not a substitute for endotracheal intubation (ETI) in severe airborne infections progressing to ARDS.
• NIV is increasingly used for dyspnea relief in end-stage patients.

Conclusions:

• NIV has expanding applications beyond traditional uses, including procedural support and palliative care.
• Contraindications include severe airborne infections requiring ETI.
• Optimal outcomes with NIV depend on a skilled team, appropriate patient selection, and device choice.
