| [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 |

| [* black] No viral filter is needed because inflowing gas is clean. A single expiratory valve contralateral to fresh gas flow is suggested. You must also wear a surgical mask because expiration is to room. |
| [* black] At 12 L/min flow, CO2 and water vapor clearance is adequate for most users. |
| [* icon_caution] You may wish to use medical air for prolonged wear. 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 when placed on a patient. |
