Abstract


By mechanically ventilated patients airway humidification amount of liquid and its influencing factors ( patient's temperature , the sick room temperature , breathing gas temperature and humidity , sputum volume and size of ventilation ) , The aim of the present study was to establish the the airway humidification amount of liquid impact factors model , so as to provide reference for clinical nurses , to reduce the complications caused by clinical critically ill patients on mechanical ventilation disease airway humidification process , such as ventilator-associated pneumonia (ventilator-associated pneumonia, VAP), thereby enhancing the the patient's quality of life . Correlation and regression analysis methods , Liaoning Province, Jinzhou Central Hospital ICU ventilator 50 patients tested . Trial, the factors affecting the amount of wet liquid as the independent variable , the amount of liquid wet as the dependent variable , Partial Correlation Analysis ( partial correlation analysis) and regression analysis to establish the model between the amount of liquid and influencing factors . Results of correlation and regression analysis , the airway humidification there was a significant relationship between the amount of liquid and its influencing factors ( P lt ; 0.05 ) , room temperature, and the amount of sputum , suction gas temperature and humidity and the amount of liquid was negatively correlated , the rest is a positive correlation . Their degree of correlation to the amount of sputum GT ; breathing gas temperatures GT ; the inhaled gas humidity gt ; ventilation size gt ; room temperature gt ; body temperature, and the establishment of a model of multiple linear regression equation between the amount of liquid and influencing factors , y = -22.68 X 1 7.49 X 2 -5.20X 3 -4.00X 4 0.01X 5 -31.87X 6 823.32. Conclusion The clinical staff in airway humidification care of mechanically ventilated patients , to balance Aikido wet Factors affecting amount of liquid , and sputum volume and inhalation of the gas temperature in these factors affect airway humidification amount of liquid main factors. From the regression model can be learned , the ward , the lower the temperature , the patient inhaled the gas humidity the smaller , the sputum less amount of the ventilator humidifier tank airway humidification more liquid .
