Mechanical Ventilation for COVID-19 Quiz

What is the purpose of maintaining PEEP in mechanical ventilation?

• To decrease the tidal volume

• To reduce the patient's respiratory rate

• To keep an open lung and prevent atelectasis

• To increase the patient's oxygen saturation

Which mode of ventilation is typically used when patients have an intact respiratory drive?

• Volume Assist Control

• Pressure Assist Control

• Pressure Support

• Volume Assist Control and Pressure Support

What is the recommended tidal volume for mechanical ventilation based on ideal body weight?

• 8-10 mL/kg

• 4-6 mL/kg

• 6-8 mL/kg

• 10-12 mL/kg

What is the minimum recommended setting for PEEP in mechanical ventilation?

• 2 cm H2O

• 10 cm H2O

• 5 cm H2O

• 8 cm H2O

What is the common inspiratory flow rate for delivering tidal volume in mechanical ventilation?

• 40-50 L/min

• 50-60 L/min

• 30-40 L/min

• 60-70 L/min

What does the inspiratory pause help distinguish in mechanical ventilation?

• Tidal volume and minute ventilation

• Resistance and compliance of the respiratory system

• Peak pressure and plateau pressure

• Inspiratory and expiratory phases

In Pressure Assist Control mode, what is the default setting for rise time?

• 0.2 sec

• 0.15 sec

• Inspiratory flow rate

What is the recommended range for plateau pressure to avoid potential lung injury?

• 25-30 cm H2O

• 20-25 cm H2O

• Less than 20 cm H2O

• Greater than 30 cm H2O

How should minute ventilation be adjusted to increase pH in mechanical ventilation?

• Increase minute ventilation

• Decrease minute ventilation

• Maintain minute ventilation

• Stop minute ventilation
