Non-Invasive Ventilation: When, Where, How to Start, and How to Stop

Area of Science:

• Respiratory Medicine
• Critical Care

Background:

• Non-invasive ventilation (NIV) is vital for respiratory failure management.
• Weaning from NIV is complex, with current practices often subjective.
• Suboptimal NIV weaning increases patient morbidity and mortality.

Purpose of the Study:

• To review the current evidence on non-invasive ventilation weaning.
• To emphasize structured approaches, objective monitoring, and predictors of weaning success.
• To support clinicians in making safe, timely, and patient-specific NIV weaning decisions.

Main Methods:

• Review of guideline-based indications and monitoring strategies for NIV weaning.
• Analysis of gradual versus abrupt weaning techniques and their efficacy.
• Evaluation of predictive tools: Rapid Shallow Breathing Index, Lung Ultrasound Score, Diaphragm Thickening Fraction, ROX index, and HACOR score.

Main Results:

• Current clinical practice for NIV weaning often lacks evidence-based protocols.
• Various predictive tools show diagnostic value in assessing weaning success.
• The care setting (ICU, step-down, general ward) impacts NIV weaning outcomes.

Conclusions:

• Structured approaches and objective monitoring are crucial for effective NIV weaning.
• Predictive tools can aid clinicians in optimizing NIV de-escalation.
• Further research is needed, particularly for NIV weaning in non-ICU settings.
