| Venturi mask | 24-50% | Increasing flow will not alter FiO2 | |
| Oxygen tent | 10-15 | 21-50% | Used mainly on children with croup or pneumonia |
| Simple mask | 5-12 | 35-55% | Never used at flows less than 5 L/min to prevent rebreathing of CO2 |
| Trach mask | 10-15 | 35-60% | Adequate flow shown by mist flowing out the exhalation port at all times |
| Partial rebreathing mask | 8-15 | 35-60% | Flow rate must be sufficient to keep bag 1/3 to 1/2 inflated at all times |
| Aerosol mask | 8-15 | 21-99% | |
| Non-rebreathing mask | 8-15 (or max) | 60-99% | Flow rate must be sufficient to keep bag 1/3 to 1/2 inflated at all times |
