The application of heated humidification oxygen therapy during weaning from ventilation in patients with severe traumatic brain injury

Objective To evaluate the effectiveness of continues heated humidification oxygen therapy during weaning from ventilation in after ventilator withdrawal.Methods 50 cases of severe traumatic brain injury patients were divided into experimental and control groups,each 25 cases.The experimental group was given airway humidification and oxygen therapy with production of oxygen therapy machine(Fisher Paykel Healthcare Corporation,New Zealand).Control group used traditional artificial nasal airway humidification of oxygen.Results The airway environmental indicators like respiratory rate,sputum viscosity,partial pressure of carbon dioxide were significantly lower than which in the control group,with a significant differences(P 0.01).The occurrence of pulmonary infection in the experimental group was lower than which in the control group(P 0.01).Conclusion The oxygen therapy machine is better than traditional artificial nose of humidification and maintain toward airway environment in severe traumatic brain injury patients,and can reduce pulmonary infection rate in a certain degree.
