1305.2 Minimum Flow Rates
JUMP TO FULL CODE CHAPTER
Medical gas and vacuum systems shall be capable of supplying the flow rates listed in Table 1305.2.
For SI units: 1 cubic foot per minute (CFM) = 0.47 L/s
Notes:
| MEDICAL SYSTEM | FLOW RATE |
|---|---|
| Oxygen | .71 CFM per outlet1 |
| Nitrous Oxide | .71 CFM per outlet1 |
| Medical Compressed Air | .71 CFM per outlet1 |
| Nitrogen | 15 CFM free air per outlet |
| Vacuum | 1 SCFM per inlet2 |
| Carbon Dioxide | .71 CFM per outlet1 |
| Helium | .71 CFM per outlet |
For SI units: 1 cubic foot per minute (CFM) = 0.47 L/s
Notes:
- 1 A room designed for a permanently located respiratory ventilator or anesthesia machine shall have an outlet capable of a flow rate of 6.36 CFM (3.0 L/s) at the station outlet.
- 2 For testing and certification purposes, individual station inlets shall be capable of a flow rate of 3 SCFM (1.4 L/s), while maintaining a system pressure of not less than 12 inches of mercury (41 kPa) at the nearest adjacent vacuum inlet.
