ABSTRAK

Oxygen is vital substance for life. Lack of absence of oxygen may render the cellular energy production to become inadequate, leading to the death of the organism. This may also happen in early postoperative patients due to the accurrence of complication, i.e., hypoventilation that results in hypoxemia. In Undata hospital, Palu, the management for early postoperative patients remained less optimal. This study was undertaken to identify the difference in the administration of nasal prong oxygen therapy (low flow)2 liters per minute and 4 liter per minute on the change of early postoperative oxygen saturation (SpO2). This study used Quasy Experiment the pre and posttest design. The independent variable was the administration of nasal prong oxygen therapy (low flow) 2 liters per minute and 4 liters per minute. The dependent variable was oxygen saturation (SpO2) with normal value of 96100%, and abnormal value, wish was regarded as hyposemia if ≤ 95%. Sample consisted of 30 individuals taken using purposive sampling method. Data were collected using observation and were analyzed by means of Wilcoxon’s Signed Ranks Test and Mann-Withey U Test. Results revealed significant difference before and after treatment, in wich the results of Wilcoxon Signed Ranks Test in group with 2 liters per minute showed Z value of -3.436, with Asymp. Sig. (2-tailed) = 0.001, with significance p ≤ 0.01. Resuls of Mann-Withney U Test revealed the Wilcoxon W (Wx) value of 224.500, Mann-Withney U = 104.500, Z = -0.637 and Asymp. Sig. (2-tailed) = 0.524 with significance difference between groups with 2 and 4 liters per minute. Thos results proved thet the administration of nasal prong oxygen therapy (low flow) of 2 liters was as effective as the administration with 4 liters per minute to prevent hypoxemia in early postoperative patients. Further studies are warranted on the factors that affect the change of oxygen saturation in early postoperative patients.
