2. A patient is receiving \( 40 \% \) oxygen via air-entrainment mask with the flowmeter set at \( 8 \mathrm{~L} / \mathrm{min} \). What is the total flow delivered to the patient? 3. A patient requires a flow rate of \( 40 \mathrm{~L} \) min to meet his inspiratory demand for gas. He is to receive oxygen via a Venturi mask at \( 24 \% \). What is the minimum setting on the flowmeter to produce the appropriate flow? A. 1L/min B. \( 2 \mathrm{~L} / \mathrm{min} \) C. \( 3 \mathrm{~L} / \mathrm{min} \) D. \( 4 \mathrm{~L} / \mathrm{min} \) 4. A patient is breathing 16 breaths \( / \mathrm{min} \) with a tidal volume of \( 525 \mathrm{ml} \). What is this patient's peak inspiratory flow?
