### Gas Exchange in Systemic Circulation#### Overview:This diagram provides a detailed representation of the gas exchange process in systemic circulation and its relationship to oxygen (O₂) and carbon dioxide (CO₂) pressures.#### Key Points:- **Oxygen Tension in Alveoli:** - The partial pressure of oxygen in the alveoli (P(O₂)) is 95 mm Hg.- **Carbon Dioxide Tension in Alveoli:** - The partial pressure of carbon dioxide in the alveoli (P(CO₂)) is 40 mm Hg.- **Gas Exchange with Systemic Cells:** - **Systemic Circulation:** - The systemic circulation carries oxygenated blood from the heart to the systemic cells. - **Systemic Cells:** - Within these cells, the P(O₂) drops to 40 mm Hg, indicating oxygen utilization by the cells. - The P(CO₂) increases to 45 mm Hg as a result of cellular respiration, where CO₂ is a byproduct.- **Carbon Dioxide Exchange:** - The systemic circulation then carries deoxygenated blood, rich in CO₂, back to the lungs. - CO₂ is expelled from the body through the respiratory process.#### Diagram Description:1. **Systemic Cells:** - Illustrated in a segment with systemic circulatory vessels (arterioles and venules). - Oxygen is depicted entering the cells (illustrated as blue arrows going into red blood cells). - Carbon dioxide is shown leaving the cells (illustrated as red arrows going out from red blood cells).2. **Gas Exchange Panels:** - Shows partial pressures of gases in a simplified format for easy comprehension. - **First Panel**: Indicates systemic cells with annotated pressures: - P(O₂) = 40 mm Hg - P(CO₂) = 45 mm Hg - **Second Panel**: Depicts oxygen exchange in alveoli: - P(CO₂) = 40 mm Hg during oxygenation. - **Third Panel**: Illustrates carbon dioxide exchange in alveoli: - P(O₂) = 95 mm Hg - P(CO₂) = 45 mm Hg which will be exchanged.3. **Graphical Arrows:** - Blue Arrows: Represent the direction of oxygen diffusion from the lungs to the bloodstream

A patient was receiving an antibiotic as a constant rate infusion at an infusion rate of 22.01 mg/h. After six times the half life of this drug, the infusion was terminated and the plasma drug concentration was determined as 3.63 mg/L and 2.79 mg/L at 5.1 hours and 8.52 hours, respectively, following the termination of the infusion. The patient started displaying lung infection symptoms again and this antibiotic was to be administered via constant rate IV infusion again. Please calculate an IV loading dose that was used to achieve a steady state of 6.28 mg/L.
