The Wonderful World of Medical Advancements:Heart-Lung Machine

Transcript of The Wonderful World of Medical Advancements:Heart-Lung Machine
when the heart is stopped Inventor Fun Facts!!! How Does it Work? Nick name is
THE PUMP First open heart Surgery
was in 1953 A machine that does the work both of the
heart (pump blood) and the lungs (oxygenate the blood). Before the heart-lung machine was invented, heart surgeons operated blindly, with the heart still pumping, or by slowly chilling the patient's body until circulation nearly stopped, or by connecting the patient's circulatory system to a second person's system during the operation The heart Lung Mechine has
evolved into a "Bypass Surgery"
Which is Commonly used today! Used Mostly in
Open Heart Surgery One of the major milestones in medicine
was the development of artificial circulation Blue blood withdrawn from the
upper chambers of the heart the blood is then pumped through an artificial lung to expose it to oxygen.
When the blood is passing through the lung (or oxygenator),
it comes into close contact with the surfaces of the machine itself. Oxygen gas is delivered to the interface between the blood and the machine, allowing the blood cells to absorb oxygen molecules directly. The blood is now red in color, owing to its rich content of oxygen. The heart-lung machine next pumps the red blood back into the patient through a tube The heart-lung circuit is a continuous loop: as the red blood goes into the body,
blue blood is drained into the pump. An American surgeon named
John H. Gibbon Jr. began pursuing the goal of total artificial circulation in 1931 after a young female patient died of blocked lung circulation. On May 6, 1953, surgery using the heart-lung machine was successfully performed on the first human, 18-year-old Cecilia Bavolek, to close a hole between her upper heart chambers Gibbon's original heart-lung machine was massive, complicated, and difficult to manage. It damaged blood elements and caused bleeding problems and severe consumption of red blood cells Presented By: Lexie Seward Citations: "File:Heart-lung-machine.jpg." Cartoon. Wikipedia.

=0&FORM=IDFRIR>. Big Ideas During the 1930's one pf the biggest trends was smoking which took a tole on a humans heart and lungs. This is why the heart lung machine was so important in saving lives. During this decayde the people didn't know that smoking could kill them.
One of the biggest natural dissasters in the 1930's was the Dust Bowl. The dust bowl was a huge storm that started when farmers would farm all the land at once with out any trees, or other things holding the soil down. So when winds picked up all the dust and soil would fly up killing people because it was so thick. The ones that survived, their lungs and hearts were badly damaged. Some of the survivors had to have there heart and lungs fixed or some times completely replaced. The heart lung machine made those fixes and replacements possible.
