| Treatment | n | End-Expiratory CO2, % | Inspiratory Duration, s | Expiratory Duration, s | PNA Burst Amplitude, µV | PNA Burst AUC, µV·s | PNA Burst Frequency, bursts/min |
|---|---|---|---|---|---|---|---|
| Veh-NSD | 6 | 5.5 ± 0.1 | 0.40 ± 0.06 | 1.16 ± 0.08 | 13 ± 2 | 3.3 ± 0.5 | 34 ± 1 |

Values are expressed as means ± SE; n, number of rats. Veh, vehicle; NSD, normal-salt diet; HSD, high-salt diet; PNA, phrenic nerve activity; AUC, area under the curve.
