How does Optiflow work?
The mechanisms of action
With Optiflow NHF therapy, you can independently titrate flow and FiO2 to match your patient’s needs. The mechanisms of action differ from those of conventional therapies, as do the resulting physiological effects and clinical outcomes.
The Optiflow NHF therapy mechanisms of action are:
- Respiratory support (through the reduction of dead space
and delivery of a dynamic positive airway pressure)
- Airway hydration
- Patient comfort
- Supplemental oxygen (if required)
These mechanisms contribute to physiological effects such as reduced respiratory rate, improved oxygenation, reduced carbon dioxide levels, and improved mucus clearance.
Clinical studies suggest that Optiflow NHF therapy may decrease the escalation of care, and improve symptomatic relief.
Note: the above mechanisms of action for nasal high flow apply to delivery through an Optiflow nasal cannula interface. The mechanisms of action differ when high flow is delivered through a tracheostomy or mask interface adapter.
