OUTCOMES 3 NETCARE EDUCATION OBJECTIVE LU 6 DN 2 STUDY GUIDE, Netcare Education: 2024 pp. 5-7. NETCARE EDUCATION 4 QUESTION! Why is oxygen so important to the body?. NETCARE EDUCATION 5 Introduction The need for oxygen is the most fundamental physiological need of a person. The absence of oxygen can lead to cellular, tissue, and organ death (Berman, et al., 2021, p. 1303). Oxygen is required to extract. energy from food. Oxygenation includes the uptake and utilization of oxygen by the tissues, while at the same time the elimination of carbon dioxide from the tissues. The processes of oxygenation include NETCARE EDUCATION breathing, gas exchange in the lungs, transportation of oxygen to the tissues via the circulatory system, uptake, and utilization of oxygen in the cells, transportation of carbon dioxide to the lungs via the circulatory system, and the exhalation of carbon dioxide via the lungs. 6 Case Study Mrs. Y, a 65-year-old female patient, is admitted to your ward with bronchitis. When entering the patient’s room, you observe her struggling to breathe. She is restless and anxious and attempts to get out of bed. Assessment:. Pulse = 98beats/min; SpO2 = 89%; Respiration = 32 breaths/min; BP = 111/89 mmHg 1. Which system of the body is involved in this scenario 2. Which main structures are involved in a patient’s struggle to breathe? NETCARE EDUCATION 3. Describe how the body will control the respiratory rate in this scenario. 4. Explain the factors affecting the respiratory function in this scenario. 5. Describe the respiratory alteration applicable to the scenario. 7. 8 NETCARE EDUCATION.
