A Comparative Study of High and Low Tidal Volume in Preventing Hypoxemia in Patients With Mechanical Ventilation After Cervical Spinal Cord Injury

This study in order to best tidal volume mechanical ventilation in patients with cervical spinal cord injury (sci) as the research point, through higher low volume Settings to find the difference of two groups of patients to prevent the incidence of hypoxemia, to find suitable Settings, tidal volume in patients with lower mechanical ventilation in patients with cervical spinal cord injury (sci) the incidence of pulmonary complications, live less intensive care unit (ICU).
