Nasal high flow in anesthesia

Request more information
The F&P Optiflow™ nasal high flow (NHF) system enables users to deliver high flow nasal oxygen, which has been shown to optimize oxygenation during general anesthesia, procedural sedation and postanesthesia recovery.

In general anesthesia
NHF has been shown to:

  • Provide effective preoxygenation
  • Provide short term supplemental oxygenation (for up to 10 minutes) during intubation

In procedural sedation
NHF has been shown to:

  • Optimize oxygenation
  • Reduce the incidence of airway-related interventions

In postanesthesia recovery
NHF has been shown to:

  • Provide positive airway pressure
  • Increase end-expiratory lung volume
