A patient has completed an SBT and is now on CPAP of 5 cmH2O with Pressure Support of 5 cmH2O. What is the primary purpose of the pressure support?

A patient receiving Pressure Support ventilation has respiratory rates increasing from 18 to 36 breaths per minute and tidal volumes falling steadily. What does this suggest?

A patient on APRV remains severely hypoxemic. Which adjustment would MOST likely improve oxygenation?

A patient is receiving SIMV at a rate of 8 breaths per minute. The patient is breathing spontaneously at 24 breaths per minute. The spontaneous breaths appear shallow and labored. Which adjustment would MOST reduce work of breathing?

A patient is receiving Volume Assist/Control ventilation. Overnight the peak inspiratory pressure increases from 28 cmH2O to 42 cmH2O while tidal volume remains unchanged. What is the primary concern?

A patient with severe ARDS is placed on APRV. Which APRV setting primarily determines oxygenation?

A patient receiving CPAP begins retaining CO2 because respiratory muscles are tiring. Which intervention is MOST appropriate?

A patient is placed on CPAP of 8 cmH2O. Which physiologic effect is expected?

What must be the distance in meters between point charge q1 = 22.0 µC and point charge q2 = -61.2 µC for the electrostatic force between them to have a magnitude of 5.76 N? (k = 9×109 Nm2/C2)

Calculate the work done by an external agent during an isothermal compression of 8.16 mol of oxygen from a volume of 25.1 L at 0°C to 17.0 L. (R=8.314J/(mol K)
