| Question | Answer |
| Anatomic Reservoir | Fills with O2 during the pause between inspiration and expiration and helps raise the FiO2 in the lungs |
| Normal Inspiratory Flow Rate | 40 to 60 LPM |
| Nasal Cannula is high flow or low flow system? | Low Flow System |
| Nasal Cannula Fi02 | 1 Lpm= 24%, 2 Lpm= 28%, 3 Lpm= 32%, 4 Lpm= 36%, 5 Lpm= 40%, 6 Lpm= 44% |
| Nasal Catheter is high flow or low system? | Low Flow System |
| Simple O2 mask is a high flow or low flow system? | Low Flow System |
| Why is the minimum flow 5 Lpm for a Simple O2 mask? | If flow rate is too low, patient will re breathe CO |
| High Flow systems | Designed to satisfy the patients inspiratory demands. Usually use a "mixing cartridge" or other feature. |
| Low Flow Systems | Not designed to satisfy all the patients inspiratory demands |
| Is the Venturi Mask a high flow or low flow system? | High Flow System |
| Qualifications of a Low Flow System | RR<25, normally 8-25; Vt= 350 ml to 700 ml, Respiratory pattern regular and consistent |
| Is the Non Breathing Mask a high flow or low flow system? | Fixed performance high flow system |
| Non Breathing Mask | Fi02= 95%, Two one way valves, Bag, Flow between 10 to 15 Lpm; Bag should never collapse. If so, flow rate is too low. |
| How to convert from a Non Breathing mask to Partial Rebreathing Mask | Remove valves and reduce flow rate by 2-3 L. CO2 does not increase because last 1/3 of air inhaled from the air is exhaled in the bag and the rest of air (CO2) exits the mask. |
| Continuous Aerosol Oxygen Delivery Devices | Trach Collar, Aerosol Tree/Briggs Adapter, Aerosol Mask, Face Tent |
| Small Volume Nebulizers | Used for short time aerosol medication administration "aerosol treatment" |
| Large Volume Nebulizers | Used for artifical airways and patients straight off vent to moisturize throat and vocal cords. Also used on Aerosol Devices |
