CVP Patient Safety and Equipment

Question 1

What is the most critical safety check before initiating cardiopulmonary bypass?

Accepted Answer

Verifying adequate anticoagulation (ACT) and ensuring the circuit is properly assembled and de-aired

Answer

Before initiating bypass, confirming adequate anticoagulation and a properly assembled, air-free circuit is essential to prevent catastrophic complications.

Question 2

What is the primary risk of inadequate de-airing of the bypass circuit?

Accepted Answer

Air embolism to the patient causing stroke or organ damage

Answer

Air remaining in the circuit can be pumped into the patients arterial system causing air embolism, potentially resulting in stroke or organ damage.

Question 3

What should a perfusionist do if the oxygenator fails during bypass?

Accepted Answer

Immediately switch to a backup oxygenator while maintaining circulation

Answer

A backup oxygenator should always be available. If the primary oxygenator fails, switching to the backup while maintaining circulation is critical to patient survival.

Question 4

What is the purpose of the level detector on the venous reservoir?

Accepted Answer

To alarm when blood level drops dangerously low, preventing air from entering the pump

Answer

The level detector prevents the catastrophic event of pumping air by alerting when the reservoir level drops below a safe threshold.

Question 5

What is the significance of checking for hemolysis during bypass?

Accepted Answer

Elevated free hemoglobin indicates red blood cell destruction that can cause kidney damage

Answer

Hemolysis (destruction of red blood cells) releases free hemoglobin which can damage the kidneys. Monitoring helps detect equipment malfunction or excessive shear forces.
