In regards to acid-base imbalance, what does "compensation" mean?

• It is the cause of the acid-base imbalance
• It is the body's attempt to correct the acid-base imbalance
• It is a measure of how severe the acid-base imbalance is
• It measures the body's ability to tolerate an acid-base imbalance - CORRECT

ANSWER: 2. It is the body's attempt to correct the acid-base imbalance

Patients A and B are both on mechanical ventilatory support.

Patient A is receiving an FiO2 of 70% and patient B is receiving an FiO2 of 30%

Which statement about these patients is most accurate?

• Patient A is inhaling 70% of the air delivered by the ventilator
• Patient A is getting 7L of oxygen
• 70% of the air being delivered to patient B is NOT oxygen
• Patient B is likely in a worse respiratory status than patient A - CORRECT ANSWER:
• 70% of the air being delivered to patient B is NOT oxygen
