Evaluation of the Relationship Between Oxygenation At Visit and the Prognosis of Patients With Covid 19

Background: determining the prognosis of the covid-19 disease is a valuable guide for estimatingthe probability of recovery, determining the type of care, estimating the required bed, length ofhospitalization and discharge of hospitalized patients. therefore, the present study was conducted with the aim of determining the relationship between oxygenation at the time of visit and the prognosis of patients with covid-19 in khatam-al-anbia hospital in zahedan in 2019-2020. method: in this retrospective cross-sectional investigation, the study encompassed individuals whowere admitted to khatam-al-anbia hospital in zahedan owing to the presence of covid-19 during the timeframe of 2019-2020. the data acquisition instrument employed in this study comprised variablessuch as age, sex, spo2 at the time of visit, underlying lung diseases, and the ultimate outcome, which were meticulously gathered and recorded from the patients' medical records. to perform the dataanalysis, the researchers utilized spss software version 21, employing both descriptive and analytical statistical methods. results: a total of 383 patients were subjected to examination, with an average age of 49.46 ± 17.57years. of these patients, 201 (52.5%) were male, while the remaining individuals were female. among the patients, 145 individuals (37.9%) had a medical history of lung diseases. ultimately, 132 patients(34.5%) were recorded as deceased. it was observed that the average spo2 level in deceased patients was significantly lower than that of discharged patients (p<0.001). furthermore, the spo2 readings in deceased patients were consistently lower than those in discharged patients, regardless of age group or gender (p<0.05). notably, the gender of the patients did not exhibit a significant association withtheir prognosis (p=0.914). conclusion: patients who are diagnosed with covid-19 and exhibit low levels of spo2 are known tohave a greater risk of mortality compared to patients who do not present with this condition. thisobservation holds true across various age groups and genders.
