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

Brief Summary: 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).

Recruitment & Eligibility

Inclusion Criteria

All critically ill adult patients with cervical spinal cord injury who require mechanical ventilation and informed consent to be admitted to the Department of Critical Care Medicine of Peking University Third Hospital were selected by the subjects or their close relatives to enter the clinical study.
