- Postinspiratory plateau pressure (PPLAT), total positive end-expiratory pressure (PEEPTOT) and arterial carbon dioxide tension (Paco2) at lowest tidal volume found in simulation by increasing respiratory rate to high levels (RRHIGH) and by using aspiration of dead space (ASPIDS) for 30 and 60 min. Values are expressed as means ± standard deviation. Differences between measured and simulated values: *P < 0.05, **P = 0.01. NS, not significant.
