1 L FIO2(24%)
6 L FIO2(44%)
Humidify with sterile water for flow > 4L/m drying
Prevent skin breakdown over ears and at nares |

Definition
5-6 L/min FIO2 40%
greater than 8 L/min FIO2 60%
Minimum of FIO2 5L/m to prevent rebreathing of carbon dioxode
Short term use
More difficult to eat,drink,and speak
Good for mouth breathers |

Definition
6-10 L/min FIO2 40-70%
Mask with reservoir and no flaps at the exhalation ports
Oxygen flow to maintain reservoir bag
1/3 to 1/2 full on inspiration.
Need to check frequency to make sure bag is inflated appropriately. |

Definition
10 L/min FIO2 60-80%
Mask with reservoir and flaps at expiration ports to prevent room air from entering the mask... May see flap over one exhalation hole only as a safety feature.
One way valve between bag and mask to prevent exhaled air from returning to bag.
Oxygen flow to maintain reservoir bag 1/3 to 1/2 full on inspiration.
Need to check frequently to make sure bag is inflated appropriately. |
