It's Topic Tuesday!

Hello Aortic Hope Family! I hope that you are having an amazing week so far. I am sure we have all heard of the term ventilators, whether it be in Medical TV shows or movies. These machines are a standard part of surgical care, particularly in complex cases involving the heart and aorta. But what exactly is a ventilator, and why is it so important?

What Is a Ventilator?

A ventilator—sometimes referred to as a mechanical ventilator or breathing machine—is a device that assists individuals in breathing when they are unable to do so effectively on their own. It is most commonly used during surgeries that require general anesthesia, in intensive care units (ICUs), or when someone’s lungs are too weak to function properly. As a result, the ventilator ensures the body receives enough oxygen and eliminates carbon dioxide, which are both critical for organ function and recovery.

How Does a Ventilator Work?

Ventilators are connected to a person’s airway through a process called intubation, in which a flexible tube is inserted into the windpipe (trachea) through the mouth or nose. Once in place, the ventilator delivers oxygen-rich air to the lungs, supports sustained respiration, removes CO2, and ensures proper respiratory parameters. These settings on the ventilator can be adjusted depending on the patient's condition, whether they need full breathing support or just assistance.

Why Are Ventilators Used During Aortic Surgery?

Aortic surgeries, including repairs for aortic dissection or aneurysm, are major procedures that are typically performed under general anesthesia. While under anesthesia, your muscles—including the diaphragm and those responsible for breathing—are temporarily paralyzed, meaning you cannot breathe on your own.

The ventilator steps in to maintain breathing throughout the procedure. In surgeries involving the chest and major blood vessels like the aorta, ensuring stable oxygen delivery and controlled breathing is essential. Any interruption in oxygen supply during such a critical operation can have serious consequences for the brain, heart, and other vital organs.

Final Thoughts

Overall, ventilators are essential tools that make major surgeries like aortic repair possible and safe. They support the body during times when it can’t sustain natural breathing, ensuring that oxygen continues to flow and carbon dioxide is removed.

Thank you so much for joining me today on an exciting Topic Tuesday and I hope you all learned some interesting facts about ventilators. Please stay safe and have a wonderful rest of your week!
