Table 6. Representative puff topography ranges observed in a sample of young adults using their preferred disposable ENDS.
| Representative Puff Flow Rates (mL/s) | ||||||
|---|---|---|---|---|---|---|
| Representative Puff Duration (s) | 20 | 25 | 30 | 35 | 40 | 45 |
| 1.0 | 20 | 25 | 30 | 35 | 40 | 45 |

Two factors, Mean Puff Duration (s) and Mean Puff Flow Rate (mL/s), at six levels each yield Mean Puff Volumes (mL) which span the range of puffing topography characteristics observed in a cohort of twenty young adult ENDS users during a natural use environment, 7 day observation period.
