The COVID-19 does not proceed the same way in every patient. It may interfere with both oxygen (O2) and carbon dioxide (CO2) exchange in the alveoli; therefore, prevent ATP generation; subsequently, restrict energy supply for the life processes of the patient. Data sets representing the course of the COVID-19 in four patients, where the disease followed dissimilar paths were reassessed after the end of the treatment, by focusing on the respiratory and metabolic energy related parameters (FiO2, PaO2, SaO2, PaCO2) and the other parameters such as HCO3, lactate, body temperature, C-reactive protein (CRP) and blood urea nitrogen levels. . . . The valuable treatment data pertinent to each individual showed that each of them needed a personal treatment method. Group based statistical analyses may cause loss of the valuable medical information, if some of the dissimilar treatment details is considered as outliers. NIH has very recently reported that, there is no sufficient data yet to recommend either for or against the use of extracorporeal membrane oxygenation (ECMO) in the treatment of the COVID-19 patients. However, the results of this study suggest that ECMO may be useful for removal of the CO2 from some of the COVID-19 patients; therefore, will be helpful if used in their treatment Daha fazlası Daha az

As an oil-importing nation, Turkey's economy is examined in the thesis by looking at its macroeconomic aggregate’s response to oil price fluctuations. Furthermore, the thesis will discuss the post pandemic coronavirus effects on energy and stock markets. Moreover, the thesis will analyze many aspects including crude oil types, production, and its relationship with other markets. On the one hand, macroeconomic aggregates will be represented by the total industrial production index, CPI, nominal exchange rate, total petroleum and other liquids production, and natural gas import prices. Error correction Model utilized for model 1: Anal . . .yzing the impact of shocks to the price of Brent oil on Turkey's macroeconomic aggregates. Model 2: examines the effects of coronavirus cases of infection on crude oil prices, stock price volatility (VIX), and the Borsa Istanbul Index (BIST-100) using an autoregressive distributed lag model. The research has econometrical and analytical areas which will use information of Brent oil prices in two models. Firstly, the correlation between Brent crude oil price and Turkish economic aggregates that will analyze monthly observations from Nov/2000 to July/2021. Secondly, estimating COVID-19 daily infected cases influence on oil and stock markets covering the period from the first infected case in Turkey 11/March/2020 until 12/April/2021. This study will add to the existing literature by bringing awareness to the significance of oil prices shocks on the Turkish economy, taking into consideration COVID19 pandemic alterations Daha fazlası Daha az
