Multiple Indicators, Multiplied Outcomes
High Flow Cannula Oxygen Therapy
Wider flow range from 2 to 80 L/min
Oxygenation Assessment Indicators
Besides SpO2 and EtCO2, indicators such as ROX, OSI, RSS, and S/F will enhance clinical decision-making, avoid delayed intubation, improve the success rate of rescue, and directly reflect treatment outcomes.

-
ROX
Ratio of SpO2/FiO2 to Respiratory Rate
Be applied to predict the outcome of HFNC in pneumonia patients with acute hypoxemic respiratory failure (AHRF).
-
OSI
Oxygen Saturation Index
gh correlation with OI in neonates with hypoxemic respiratory failure.
-
RSS
Respiratory Severity Score
edical providers can use RRS to access patients oxygenation levels without arterial blood gas (ABG) results.
-
S/F
SpO2/FiO2 Ratio
A reliable alternative indicator of the P/F ratio (PaO2/FiO2) when there is no ABG results.
