Beschreibung
Inclusion Criteria:
- Age ≥18 years
- Presence of acute respiratory failure (ARF)
- Receiving HFNC treatment for ≥24 hours
Exclusion Criteria:
- Post-extubation HFNC use or tracheostomized patients
- Respiratory acidosis (pH <7.35) or clinically significant acute hypercapnia (pCO₂ >50 mmHg with worsening from baseline)
- Long-term home NIV or home CPAP use
- Do-not-intubate (DNI) orders precluding escalation to invasive mechanical ventilation
- Life expectancy ≤48-72 hours due to terminal non-respiratory disease
- Neurological impairment or deep sedation preventing safe HFNC use (e.g. coma or severe uncontrolled delirium)
- Technical contraindications to HFNC (i.e. facial trauma, maxillofacial surgery, severe nasal obstruction)
- Refusal to participate or inability to provide informed consent

Kein Eingriff: Non-protocolized weaning
Non-protocolized weaning according to standard clinical practice: HFNC assessment every 24 hours and discontinuation based on physician clinical judgment.
|
|
|
Experimental: Protocolized weaning
Protocolized weaning using ROX index + FiO₂
|
HFNC discontinuation based on ROX index ≥9.2 and FiO₂ ≤40%
