Breathing during relaxed wakefulness

TTOT(s)VT(l)V˙(l/min)Petco2 (mm Hg)
Group A5.4 (2.1)0.58 (0.2)7.44 (2.5)41.0 (4.2)
Group B4.2 (0.4)0.43 (0.1)6.02 (1.31)38.3 (2.0)
  • Group mean values (SD) for breath duration (TTOT), tidal volume (VT), ventilation, (V˙) and end tidal PCO2 (Petco 2) measured during relaxed wakefulness in patients with an RLM lesion plus a low ventilatory sensitivity to inhaled CO2 (group A; n=6) and patients of the non-RLM group with a normal sensitivity to inhaled CO2 (Group B; n=5).
