This study aims at comparing of closed- and open-system endotracheal suctioning on the effects of arterial oxygenation and breathing effort during mechanical ventilation without pre-oxygenation. The independent variable is the endotracheal suctioning method and the dependent variables are the arterial blood oxygen pressure tested from the laboratory and the pressure-time product monitored by the pneumotachograph. The sample consisted 30 patients at the intensive care unit of a medical center in northern region of Taiwan. A two groups cross-over experimental research design was applied, in which two patients were selected as a group and were randomly assigned one into Model 1, a closed-open and the other Model 2, an open-closed sequencing of endotracheal suctioning system. Thirty minutes after last data collected, patients' closed endotracheal suctioning system were transformed into open endotracheal suctioning system, and the same measures were repeated for tests of arterial blood oxygen pressure and pressure-time product. Result from the modified analysis of GEE model shows that the decrease of the arterial blood oxygen pressure between pre- and post-endotracheal suctioning on the closed endotracheal suctioning system is less than that of the open endotracheal suctioning system by 11.18 mmHg, but the difference does not reach the statistical significance level (p = .10).Pressure-time product between pre- and post-endotracheal suctioning on the closed endotracheal suctioning system is less than that of the open endotracheal suctioning system by 27.04 cmH2O.sec/breath, but the difference does not reach the statistical significance level (p = .39).It is suggested that a large sample size should be applied to retest these two hypotheses. Results of this study can be used as a reference to those who care for patients that are highly dependent on ventilators with high concentration of oxygen.
