Pre-read: M&M Chapters 3,23

Content outline

• Compliance and resistance

• Peak pressures and plateau pressures

• Modes of ventilation

Questions

• Draw the flow and pressure traces for pressure control ventilation, assuming that there is still flow at the end of inspiration. What would happen to minute ventilation if you keep all settings the same but decrease the respiratory rate?

• Draw the flow and pressure traces for a volume control ventilation. What would autoPEEP look like? What are some strategies to decrease the autoPEEP?

• If you are doing volume control ventilation, and you get a high pressure alarm, are you worried? What would you do?
