Learning Objectives

Sophia is studying respiratory physiology and wants to estimate the minute ventilation for women using body surface area (BSA). What formula should she use?

• Women = 3 × BSA

• Women = 3.5 × BSA

• Women = 4 × BSA

Daniel is conducting an experiment on respiratory physiology. He needs to adjust the minute ventilation of a patient. Fill in the blank: Minute ventilation should be decreased by 9%/°C between ___°C and 37°C.

• 35

• 33

• 30

• 32

Daniel wants to calculate his Ideal Body Weight (IBW) in pounds. What formula should he use?

• 106 + 6(H - 60)

• 105 + 5(H - 60)

• 100 + 4(H - 60)

• 110 + 7(H - 60)

Kai is measuring the volume of air he breathes in during a respiratory exercise. Calculate the tidal volume (VT) if the inspiratory time (Ti) is 2 seconds and the flow rate (V̇) is 300 mL/sec. Use the formula VT = V̇ × Ti.

• VT = V̇ × Ti = 300 mL/sec × 2 seconds = 600 mL.

• VT = V̇ × Ti = 300 mL/sec × 2 seconds = 500 mL.

• VT = V̇ × Ti = 300 mL/sec × 2 seconds = 700 mL.

• VT = V̇ × Ti = 300 mL/sec × 2 seconds = 400 mL.

Inspiratory pause is not commonly used in clinical practice because:

• it is difficult to perform.

• it provides no clinical benefit.

• it can cause patient discomfort.

• it is time-consuming.

Kai is a respiratory therapist who has just initiated pressure ventilation at low pressure for a patient. What should he check and adjust after this procedure?

• A) PEEP

• B) V_T

• C) PSV

• D) PCV

During a clinical training session, Anika is learning about ventilator settings. She needs to set the initial settings for _______ which include setting baseline pressure and determining VT in a type of pressure ventilation.

• PSV

• CPAP

• SIMV

• ACV

Michael is a respiratory therapist working in a hospital. He needs to calculate the Pressure Support Ventilation (PSV) for a patient on pressure support ventilation. What is the formula he should use?

• PSV = (PIP – Pplateau)

• PSV = (PIP + Pplateau)

• PSV = (PIP – Pplateau)/flow

• PSV = (PIP + Pplateau)/flow
