Determination of oxygenation status is very important in hypovolemic shock patients treatment, oxygenation status can be seen in the patient's clinical sign and examination of SpO2 and PaO2. PaO2 examination is a gold standard but has the disadvantage of less available and invasive, while SpO2 by Pulse Oximeter is easy to do, this research try to determine the correlation between SpO2 pulse oximeter and PaO2 on blood gas analysis. This research is Cross Sectional analytics, the subject of this research were 39 hypovolemic shock patients admitted to Emergency Room RSU DR Pirngadi Medan between October 2019 - February 2020, correlation between SpO2 (pulse oximeter) - PaO2 (blood gas) were measured by Pearson Correlation . O The name of this article is: f the 39 samples 41.8% 40-60 years, 30 (76.9%) with systolic under 100 at admission to the ER, 16 (41%) came with hypoxic conditions SpO2 <93%. Mean difference of SpO2 was 4.6 points lower than SaO2 blood gas, and 5.2 points lower at systolic <100mmHg, lower 5.6 points <90 mmHg. In the Pearson SpO2 - PaO2 Correlation test in systolic <100mmHg obtained correlation (r =0.423; p = 0.020) and in systolic <90 mmHg (r = 0.411; p = 0.04). The name of this article is: Clinicians are expected to wisely assess the SpO2 results in Hypovolemic Shock patients where there are lower grades of 4.6 - 5.6 points, we found correlation between SpO2 - PaO2 in hypovolemic shock conditions.
