Effect of artificial nose on preventing ventilator-associated pneumonia in the critical patients with ;mechanical ventilation

Objective To compare the effects of artificial nose and electric heating thermostat humidification jar on preventing ventilator-associated pneumonia of severe mechanical ventilation .Methods One hundred and eighty patients who respectively used the artificial nose （ the experimental group ） and electric heating thermostat humidification jar （ the control group ） were matched according to the age and sex , each with 90 cases.The effect of humidification, the incidence rate of ventilator-associated pneumonia （VAP） and the mortality rate were compared between the two groups .Results The cases of Grade Ⅲ sticky sputum were 19 cases in the experimental group , and were 34 cases in the control group , and the difference was statistically significant （χ2 =6.83, P 0.05）.Conclusions The artificial nose can reduce the incidence rate of VAP , and decrease the nursing workload and the burden of patients to a certain extent .
