Abstract: Introduction: At no point in the history of medicine has the importance of point-of-care testing (POCT) devices, tests and methods verification and utilisation been recognised and accepted than during the coronavirus pandemic. Blood gas analysers offer the best form of POCT and this has been demonstrated in the management of coronavirus patients admitted to hospital intensive care units with respiratory challenges. The new analysers were evaluated in compliance with the Clinical Laboratory Improvement Amendments (CLIA) regulation. The new method must be evaluated by comparison to the central laboratory or the outgoing analyser. The study was undertaken to verify if the new instrument, OMNI S b221 matches the well-established analysers currently in use at the hospital. Objectives: To evaluate method performance of pH, the partial pressure of carbon dioxide (pCO2), the partial pressure of oxygen (pO2), glucose, lactate, and electrolytes on OMNI S b221 blood gas analyser. Materials and Methods: To analyse the method performance of the pH, pO2, pCO2, glucose, lactate and electrolytes (Na+, K+ Ca++) on OMNI S b221 blood gas analyser 40 samples run on OMNI S b221 blood gas analyser were compared with the results obtained from ABL700, GEM PREMIER for all the parameters and the Roche Hitachi 917 analyser to compare two electrolytes (Na+ and K+). The correlation coefficient was calculated for the results obtained from each paired set of instruments (ABL 700 vs GEM PREMIER and ABL 700 vs OMNI S b221). Comparability between analyser methods performance was determined using linear regression analysis. Results: The correlation coefficient between the paired analytical platforms were all between 0.81 and 0.99, demonstrating a strong linear relationship. The coefficient of variation for all the parameters were less than 2 also demonstrating good precision. Conclusion: OMNI S b221 blood gas analyser correlated well with the outgoing ABL 700, GEM PREMIER blood gas analyser and the central laboratory analyser, Roche Hitachi 917 and therefore, verified as a good platform to run arterial blood gas samples.

Abstract: Introduction: Epidemiological investigation of Mortality is essential for health policy control of risk factors and disease. Obtaining this information is the essential basis for planning, management and evaluation, and accountability in countries' health sector. Studying Mortality and its etiologic factors are the most appropriate strategies to reduce Mortality. Objective: The study aimed to investigate the causes of death and prognostic factor of death in patients referred to the emergency department. Method: this was a cross-sectional study from 2016 to 2018 at Tohid Teaching Hospital in Sanandaj. All history and clinical examination data and Para clinical study of the patients who had expired in the first 24 hours after emergency department admission were collected in questionnaire sheets. The data was interred into spss software and analyzed using descriptive statistics frequency and percentage. Result: 73 patients, 43.8% female, and 41% male with a mean age of 63.6 years old 20-90 evaluated in our study. The first common chief complaint of the patients was chest pain 24.7%, and the most common past medical disease in the patients was hypertension 28.8% also the first common reason of death was ischemic heart disease 31.5%.43.8% of patients had abnormal electrocardiograms, 19.2% had dysrhythmias, and 24.6% had ischemic changes. Laboratory results also showed that the prevalence of sodium imbalance was 53.5%, and potassium and calcium imbalance were 37.9%& 80.8%. Also, 80.8% of patients had PH abnormalities, 30.1% acidosis, and 50.7% alkalosis. Conclusion: According to the results, it can be concluded that patients with cardiac problems or a history of cardiovascular disease are the highest risk patients and should be considered more serious. Also, electrolyte and blood gas imbalance were prevalent in these patients.
