Table 1. Lung Mechanic and Ventilatory Variables
Values are mean ± SD.
* Tested on a randomized basis.
†P < 0.05,
‡P < 0.01,
§P < 0.001 compared with airway pressure release ventilation (APRV) with spontaneous breathing.
∥P < 0.05,
#P < 0.001 compared with APRV without spontaneous breathing, high tidal volume (Vt).
Fio2= fraction of inspired oxygen; Paw= airway pressure; Pes= esophageal pressure; Phigh= high airway pressure level; Plow= low airway pressure level; RR = respiratory rate; V̇e = minute ventilation.
