Nasal Cannula at 2L/min | 28% FiO2 |
Nasal Cannula at 3L/min | 32% FiO2 |
Nasal Cannula at 4L/min | 36% FiO2 |
Nasal Cannula at 5L/min | 40% FiO2 |
Nasal Cannula at 6L/min | 44% FiO2 |
O2 in the air | 21% |
What range of % of FiO2 can a nasal cannula provide? | 24-44% |
What range of rates can O2 be set at on a nasal cannula? | 1 to 4L/min |
Simple Face Mask 5-6L/min | 40% FiO2 |
Simple Face Mask 6-7L/min | 50% FiO2 |
Simple Face Mask 7-8L/min | 60% FiO2 |
Simple Face Mask >8L/min | 60% FiO2 |
What range of % FiO2 can a simple face mask provide? | 40-60% |
What range of rates can O2 be set at on a simple face mask? | 5-8L/min |
Venturi mask 4L/min | 24-28% FiO2 |
Venturi mask 8L/min | 35-40% FiO2 |
Venturi mask 12L/min | 50-60% FiO2 |
What range of % FiO2 can a venture mask provide? | 24-60% |
What range of rates can O2 be set at on a Venturi mask? | 4, 8, or 12 L/min |
What are the advantages of a nasal cannula? | safe and simple; easily tolerated; delivers low concentrations while allowing the client to eat, speak, and drink; does not impede eating or talking; inexpensive; disposable |
What are disadvantages of a nasal cannula? | unable to use with nasal obstruction; drying to mucous membranes; can dislodge easily; causes skin irritation or breakdown; clients breathing pattern will affect exact FiO2 |
What are advantages of a simple face mask? | assist in providing humidified oxygen |
What are disadvantages of a simple face mask? | Exact FiO2 level is difficult to estimate; requires high FiO2 levels to prevent rebreathing of carbon dioxide; client inhales room air through side holes in the mask |
What are advantages of Venturi masks? | controls the amt of specified oxygen concentration; does not dry mucous membranes, delivers humidity with oxygen concentration |
What are disadvantages of Venturi masks? | hot and confining; increased levels of humidification can irritate skin; a specific flow rate is necessary to deliver a specific FiO2, FiO2 can decrease if the mask does not fit; interferes with eating and talking |
What range of % FiO2 can a partial rebreathing reservoir bag mask provide? | 40-60% |
What range of rates can O2 be set at on a partial rebreathing reservoir bag mask? | 6-10 L/min |
What range of % FiO2 can a nonrebreathing reservoir bag mask provide? | 60-100% |
What range of rates can O2 be set at on a nonrebreathing reservoir bag mask? | 6-15 L/min |
What range of % FiO2 can a face tent provide? | 28-100% |
What range of rates can O2 be set at on a face tent? | 8- 12 L/min |
What range of % FiO2 can an oxygen hood provide at 5-8L/min? | 24-40% |
What range of % FiO2 can an oxygen hood provide at 8-12L/min? | 40-85% |
What range of % FiO2 can an oxygen tent provide? | up to 50% |
What range of rates can O2 be set at on an oxygen tent? | 10-15L/min |
What is the lowest flow rate a nasal cannula can be set on? | 1L/min |
What is the highest flow rate a nasal cannula can be set on? | 6L/min |
What is the lowest flow rate a simple face mask should be set at? | 8L/min |
What is the highest flow rate a simple face mask should be set at? | 12L/min |
What is the lowest flow rate a mask with a reservoir bag should be set at? | 6L/min |
Why do masks with reservoir bags have to have the flow rate set above 6L/min? | below 6L/min there is a risk of carbon dioxide rebreathing |
What is a partial rebreathing reservoir bag mask? | mask with no inspiratory valve so that the beginning portion of exhaled air returns to the bag and mixes with the inspired air; ports allow most expired air to escape |
What is a nonrebreathing reservoir bag mask? | mask with valves that close during expiration so that the exhaled air does not enter the reservoir and is not rebreathed; valves close on inspiration to prevent inhalation of room air |
What is a face tent? | soft aerosol mask that fits loosely around the face and neck |
What are the advantages of a face tent? | convenient for providing humidification and oxygenation, alternative to an aerosol mask for those who feel claustrophobic |
What are the disadvantages of a face tent? | oxygen concentration cannot be controlled, difficult to keep in place |
What is an oxygen hood? | a disposable vinyl box that fits over a child’s head to provide warm humidified oxygen at a controlled temperature |
What flow rate should an oxygen hood not be set at and why? | set no less than 5 L/min or it could lead to carbon dioxide narcosis |
What is an oxygen tent? | a canopy that encloses the child and is used to provide oxygen, humidification, and a cool environment to control temperature |
