COVID-19 through the health care process. In the theoretical part of the paper, the structure and virulence of the virus that causes the disease COVID-19, the mode of transmission, diagnosis, treatment and complications will be presented using data from the literature, while the specifics of the health care of a sick pregnant woman will be presented in the Discussion chapter. DISCUSSION: Patient K.V., aged 30 years and 33 weeks pregnant, is being transferred from the Infectious Diseases Clinic to the Intensive Care Unit of the COVID ICU of the Split Clinical Hospital Center due to the need for continued treatment. Two weeks before hospitalization, the patient developed symptoms of a COVID-19 infection with a positive PCR result, while she is in the 33rd week of gestation with an orderly and regularly controlled pregnancy. Due to worsening respiratory status and the development of ARDS, the patient required the support of V-V extracorporeal membrane oxygenation. After the end of the infectious period, he was transferred to the ICU Firule for cardiac surgery patients of KBC Split for the continuation of treatment. Nursing care for the patient after the implementation of VV ECMO support included monitoring of vital functions, signs of bleeding and infection, application of therapy as prescribed by the doctor, implementation of personal hygiene, prevention of pressure ulcers and application of nutritional support. CONCLUSION: Extracorporeal membrane oxygenation is a treatment strategy to support patients with acute respiratory failure and has been successfully used in the treatment of ARDS associated with COVID-19. Through the process of health care, nursing diagnoses and patient care are presented.
