The Effect of Suction Towards Oxygen Saturation to Patients in Intensive Care Unit: Literature Review

Introduction: Oxygen saturation is the percentage of Hb in blood related to oxygen in the arteries. An oxygen saturation value of less than 95% indicates that the patient is hypoxaemic. Suction is an intervention often performed by nurses to patients with critical illness. The objective is to identify the value of oxygen saturation and the effect of suctiontowards oxygen saturation value to patients in ICU. Research Method: The method used literature review with articles indexed by SINTA, SCOPUS and Google Scholar. The article used experimental design with a pretest and posttest design. Articles were from 2011 to 2020 and obtained 11 suitable articles. The variableswere suction and oxygen saturation. The measuring instruments used observation sheets, pulse oximetry and questionnaires. Result: The results of 11 articles were obtained based on literature review of results of oxygen saturation values pre-test which were below normal with a minimum value of 48.1 and a maximum of 100, while the oxygen saturation post-test value with a minimum value of 42.6 and a maximum of 100 to patients in ICU and there were significant changes in the value of oxygen saturation on pre suction and post suction with a value of p <0.05. Conclusion: there was an effect of suction towards oxygen saturation value to patients in ICU.
