Who replaced the "cut down" approach with the percutaneous method? | Dr. Sven Seldinger |
What does POBA mean? | Plain old balloon angioplasty |
what is the first corner stone of CVIS? | safe catheter insertion |
what is the second corner stone of CVIS? | hemodynamic measurements |
what is the third corner stone of CVIS? | quality angiography |
what is the fourth and last corner stone of CVIS? | integration of procedural findings with the clinical assessment |

On average what should be the O2 concentration in the right atrium when it returns from the body? | 75% |
why did the use of pneumoencephalogram mostly stop? | CT scans were created |
What was an "Aortic Root Shot"? | it shows the coronary arteries coming out of the aorta with use of contrast |
What did Stephen Hales do in 1711? | the first person to measure blood pressure. He also invented several devices, including a ventilator |
How is a Pneumoencephalogram performed? | 10cc's of spinal fluid is replaced with air, the patient is then tilted and spun until the air bubble reaches the ventricles in the brain |
Why is air pushed into the brain's ventricles during a pneumoencephalogram? | The air is a different density than the brain tissue, so we are able to visualize the shape of the ventricles |

what is a vagal response | the nervous system that regulates heart rate and blood pressure malfunctions in response to a trigger such a pain |
what is Facilitated PCI? | use of thrombolytic agents for myocardial infarctions |
what is facilitated PCI still used for? | Patients have heart attacks in small hospitals before they are transported for treatment. |
What limited the use of x-rays? | Overheated due to how many images per second needed for CVIS |
How is the percutaneous method (Seldinger Technique) Performed? | hollow needle is used, then the wire is poke through needle, needle is removed and catheter is inserted over the wire |
what is the "cut down approach" (Sones Method)? | a vein is surgically exposed for access, causes lot of trauma |
Who used hollow reeds and colored dyes to understand how blood flow worked? | Christopher Wren |
how is a selective coronary angiography performed? | The catheter is placed in a coronary artery, this provides a more detailed image of a specific area and multiple angles |
What is non-selective angiography? | The catheter is placed in the aortic root and a large amount of contrast in injected. only provides one angle for an image. |
