Published recommendations underscore the breadth of nasal high flow therapy application

Data from hundreds of controlled trials have been consolidated into clinical practice guidelines and recommendations.
 
 
Research interest in NHF is increasing. Over the past decade >350 publications per year (on average) have been cataloged on PubMed.

A significant number of controlled trials, systematic reviews and meta-analyses are included.

Medical societies around the world are now in a position to create recommendations that may change clinical practice.

PRIMARY SUPPORT - MEDICAL
Patients with:
Acute respiratory failure (ARF)
General recommendations for the delivery of supplemental oxygen forpatients who require oxygen (AARC).Aim for SpO2 range of 94–98% for most of hospitalized patients (included critically ill patients) ---- Aim for 88–92% for patients with COPD ---- Aim for 88–95% for patients with ARDS ---- Consider early initiation of NHF. RECOMMENDATION

        black dot - Photos | Facebook    
Acute respiratory distress syndrome (ARDS)              
ARDS (Joint committee of 3 Japanese societies) We suggest conducting non-invasive respiratory support (NPPV, HFNC) instead of conventional oxygen therapy as an initial respiratory management for adult patients with acute respiratory failure suspected of having ARDS if there are no contraindications for non-invasive respiratory support or if organ failure other than respiratory failure is absent. NPPV (weak recommendation/moderate certainty of evidence: GRADE 2B). HFNC (weak recommendation/moderate certainty of evidence: GRADE 2B).Recommendation (CQ 16) https://pubmed.ncbi.nlm.nih.gov/35799288/
