Objective: Aim of current study is to determine the effectiveness of prone position in patients presented with severe coronavirus disease. Study Design: Observational /Retrospective study Place and Duration: King Salman Armed Forces Hospital Tabuk KSA. Feb 2021-Dec 2021 Methods: This research comprised a total of 85 patients with respiratory failure who were admitted to the ICU. Patients ranged in age from 20 to 75. After obtaining written permission from each patient, demographic information such as age, gender, and BMI was collected. A and B were the two groups of patients that were studied. Group A included 40 patients with COVID-19 who completed prone position testing, whereas group II included 45 patients as a comparison group. During the 15-day follow up period, patients in group A were remained in a prone posture whereas those in group B were subjected to invasive ventilation. Outcomes among both groups were compared in terms of mortality, hospital stay and reduction in intubation rate. Analyzation of data was completed by using SPSS 24.0 version. Results: The majority of the patients were men, with 60 (70.6%) of the total, while the others were females, with 25 (29.4%). The mean age of the patients in the prone posture group was 48.12 years, with a mean BMI of 27.5 kg/m2, whereas the mean age of the patients in the control group was 50.4 years, with a mean BMI of 27.9 kg/m2. The average time spent in the prone position was 6.08 hours. When comparing the prone group to the controlled group, the mean PF ratio was higher in the former. The average length of stay in group A was 7.2 days, whereas the average length of stay in group B was 10.5 days. Group A had a death rate of 2 (5%), while group B had a mortality rate of 5 (11.1%). Conclusion: As a result of this research, we came to the conclusion that the prone position was an effective and safe approach for reducing intubation, mortality, and hospital stay in patients of COVID-19. After this procedure, no side effects were observed. Keywords: Respiratory Failure, Mortality, Prone Position, Covid-19,
