Personalized evaluation of oxygen and carbon dioxide exchange in Covid-19 patients with regard to energy homeostasis

Yılmaz, Bayram

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 prote ...Daha fazlası
