- A patient was connected an artificial ventilation device during a surgery on the gastrointestinal tract. 60 minutes after the start of the operation, a gas composition of the blood and pH were examined: - PaCO₂ = 26 mm Hg - pH = 7.5 Questions: 1. Give an opinion on the gas composition of blood and the acid-base state 2. What type of violation of external respiration is developed in the patient? 3. Give a definition of this type of respiratory pathologyA patient receives an intravenous (IV) solution that flows at the rate of 150 mL per hour. How much fluid does the patient receive in 20. min? (Answer = 50 mL) How long does it take for the patient to receive 90. mL of fluid? (Ans. = 0.6 hr or 36 min.) If the IV bag holds 600. mL of fluid, how many minutes does it take to empty the bag?
