Practice exercise (made-up values, not clinical guidance). The gauge on a size E oxygen cylinder reads 1750 psi. Its cylinder factor is 0.28 L/psi. How many litres V can be used before the safe residual of 200 psi is reached?
Practice exercise (made-up values, not clinical guidance). The gauge on a size D oxygen cylinder reads 800 psi. Its cylinder factor is 0.16 L/psi. How many litres V can be used before the safe residual of 200 psi is reached?
Practice exercise (made-up values, not clinical guidance). A patient breathes 19 times a minute with a tidal volume of 700 mL. The anatomical dead space is 150 mL. Find the alveolar ventilation V̇A in L/min.
Practice exercise (made-up values, not clinical guidance). A size D oxygen cylinder (factor 0.16 L/psi) reads 750 psi and runs at 6 L/min. Keeping a safe residual of 200 psi, how many minutes t will it last? Round down to a whole minute.
Practice exercise (made-up values, not clinical guidance). A transfer will take 30 minutes. The size E cylinder (factor 0.28 L/psi) reads 1750 psi. Keeping a safe residual of 200 psi, what is the highest whole-number flow Q in L/min that lasts the whole transfer?
Practice exercise (made-up values, not clinical guidance). A transfer will take 60 minutes. The size E cylinder (factor 0.28 L/psi) reads 1850 psi. Keeping a safe residual of 200 psi, what is the highest whole-number flow Q in L/min that lasts the whole transfer?
