What are the three categories of respiratory failure based on underlying pathophysiology?

• Ventilation failure, Circulation failure, Oxygenation-ventilation failure

• Respiratory muscle failure, Oxygenation failure, Circulation failure

• Ventilation failure, Oxygenation failure, Oxygenation-ventilation failure

• Ventilation failure, Oxygenation failure, Circulation failure

What is the equation mentioned in Chapter 2 that explains the relationship between CO2 production and ventilation?

• PaCO2 = CO2 production - dead space ventilation

• PaCO2 = CO2 production * dead space ventilation

• PaCO2 = CO2 production / dead space ventilation

• PaCO2 = CO2 production + dead space ventilation

What can reduce dead space ventilation according to the text?

• Morbid obesity and severe kyphoscoliosis

• Liver failure and renal failure

• ALS and myelitis

• Intracranial hemorrhage and encephalitis

Which of the following is a cause of reduced respiratory drive?

• Trauma

• Liver failure

• Spinal cord disease

• Peripheral neuropathy

What is the primary function of mechanical ventilation in severe disturbances in gas exchange?

• To reduce respiratory muscle strength

• To assist the respiratory system and restore PaCO2, PaO2, or both to normal

• To decrease PaO2

• To increase PaCO2

What is the main cause of ventilation failure as defined in the chapter?

• Decrease in central respiratory drive

• Increase in respiratory muscle strength

• Increase in chest wall compliance

• Increase in CO2 production

Which disease can interfere with the transmission of neural signals from the brain to the respiratory muscles?

• ALS

• Guillain-Barre syndrome

• Morbid obesity

• Liver failure
