[title] Configuration for Oxygen or Medical Air
[* black] Simplest Halo configuration is for oxygen or medical air. This configuration uses the fewest consumables and is ideal for brief, aerosolizing procedures such as intubation or airway removal in a fixed location
[* black] No viral filter is needed because inflowing gas is clean. A single expiratory valve contralateral to fresh gas flow is suggested.
[* black] At 10 L/min flow, CO2 and water vapor clearance is adequate for most users.
[* icon_caution] You may wish to use medical air for prolonged use. Measured FiO2 in Halo is typically > 95%. Usual fire hazard warning for O2!
[* icon_note] Exceptionally high FiO2 delivery capability may make this configuration useful on a patient.
