Heart Lung Machine Quiz

What is the main function of a heart lung machine?

• To provide oxygen to the brain

• To regulate blood sugar levels

• To make the heart and lungs work harder

• To temporarily take over the function of the heart and lungs during surgery

Why is a heart lung machine used during open-heart surgery?

• To cool down the heart and lungs

• To provide extra oxygen to the heart and lungs

• To measure the size of the heart and lungs

• To temporarily take over the function of the heart and lungs

How does a heart lung machine help in maintaining blood circulation during surgery?

• Administering anesthesia to the patient

• Filtering the blood for impurities

• Stimulating the heart to beat faster

• Temporarily taking over the functions of the heart and lungs

Name one component of a heart lung machine.

• Heart monitor

• Blood pressure cuff

• Oxygenator

• Stethoscope

What is the purpose of the oxygenator in a heart lung machine?

• To remove oxygen from the blood

• To increase carbon dioxide levels in the blood

• To add oxygen to the blood and remove carbon dioxide

• To cool down the blood

What is the role of the pump in a heart lung machine?

• Supplying oxygen to the blood

• Filtering the blood before returning it to the patient

• Regulating the temperature of the blood

• Circulating the blood through the machine and back to the patient's body

Explain the process of how a heart lung machine operates during open-heart surgery.

• It operates by removing the heart from the body and replacing it with a mechanical pump.

• It is only used for lung surgeries, not heart surgeries.

• It is used to cool down the patient's body temperature during surgery.

• It takes over the functions of the heart and lungs during open-heart surgery.

What are the advantages of using a heart lung machine during cardiac surgery?

• It increases the risk of complications during surgery

• It allows the surgeon to stop the heart and maintain blood circulation and oxygenation.

• It is not effective in maintaining blood circulation and oxygenation

• It is more expensive than traditional surgical methods

How does a heart lung machine reduce the risk of complications during surgery?

• It causes more bleeding and makes the surgery more difficult

• It takes over the function of the heart and lungs during surgery, allowing the surgeon to work on a still and bloodless field, reducing the risk of complications.

• It has no effect on the risk of complications during surgery

• It increases the risk of complications by interfering with the natural function of the heart and lungs

What impact does the use of a heart lung machine have on the success rate of open-heart surgeries?

• It increases the success rate of open-heart surgeries.

• It only impacts the success rate of closed-heart surgeries.

• It has no impact on the success rate of open-heart surgeries.

• It decreases the success rate of open-heart surgeries.
