This study aims to identify the effect of right lateral resting position on hemodynamic and level of comfort on heart failure patients. The method of this research was randomized controlled trial (RCT) withcross – over design. Twenty patients with heart failure stage II and III (15 men and 5 women) at the Harapan Kita Cardiovascular Hospital were participated. Blood pressure, Mean Arterial Pressure (MAP), heart rate (HR), respiratory rate (RR) and SaO2 were measured before and after setting up the position using bedsite monitor.The level of comfort was measured by using the Verbal Rating Scale Questionnaire. Measurements were taken in the morning (09:00 to 11:00 AM) and evening (04:00 to 06:00 PM). The results of this study showed there are significant effects of right lateral position on the Systolic Blood Pressure (SBP) (Morning: p value .000; Evening: p value: .017), Diastolic Blood Pressure (DBP) (Morning: p value 0.004), MAP (Morning: p value 0.001), HR (Evening: p value 0.008) before and after setting up the right lateral position. There is a significant difference between group on the level of comfort (Evening: p value 0.041). Recommendation of this study is setting the right lateral position can used as one of nursing intervention for maintain hemodynamic and increase level of comfort on patients with heart failure.enright lateralhemodynamiccomforheart failureUR-Proceedings
