Table 1. Evolution of the Main Hemodynamic, Ventilatory, and Arterial Blood Gas Parameters in Nine Patients with Life-threatening Pulmonary Contusion during Conventional Mechanical Ventilation and High-frequency Jet Ventilation (HFJV)

Initial data with HFJV were obtained within 1 h after the onset of HFJV. Data are mean ± SD.

* P < 0.05 versus admission.

† P < 0.05 versus conventional ventilation.

Paco²= arterial partial pressure of carbon dioxide; Pao²= arterial partial pressure of oxygen; Fio²= inspired fraction of oxygen; EEP = end-expiratory pressure; P^aw= mean airway pressure; MAP = mean arterial pressure.
