MEDICAL ANIMATION TRANSCRIPT: The respiratory system regulates oxygen and carbon dioxide levels within the blood. Respiration includes ventilation, gas exchange between the air, blood, and tissues within the body, and the use of oxygen for metabolism. Inhalation allows oxygen to enter the body, pulling air into the nose and mouth, lungs, and into the air sacs called alveoli, where gas exchange takes place. Alveoli move freely when air is inhaled and exhaled. Capillaries are small blood vessels that line the walls of the alveoli. During gas exchange, oxygen enters and carbon dioxide exits the bloodstream via the alveolar-capillary membrane. Once oxygen molecules move from the alveoli into the capillaries, they dissolve into the plasma and enter the red blood cell or erythrocyte. Erythrocytes contain millions of soluble proteins called hemoglobin. Hemoglobin contains four subunits each capable of binding one molecule of oxygen. Once one molecule of oxygen binds to one of the subunits, the other sites bind oxygen more readily. Dissolved and bound oxygen flows through the arterial bloodstream to capillaries within tissues. Upon arrival, carbon dioxide loading of the erythrocyte promotes oxygen unloading. Oxygen metabolism within cells produces carbon dioxide gas as a metabolic waste. Carbon dioxide exits the cells and tissues and is converted into bicarbonate within the erythrocytes. Converting carbon dioxide to bicarbonate releases hydrogen ions that decrease oxygen affinity for hemoglobin, freeing the oxygen to be delivered to tissue cells. After delivering oxygen to the tissues, the carbon dioxide-rich blood returns to the lungs through the venous circulation and then to the pulmonary artery. Inside each erythrocyte, the bicarbonate conversion is reversed, recreating carbon dioxide, which diffuses across the erythrocyte into the alveoli and lungs and is excreted out of the body. ♪ [music] ♪
"At 3 PM it hit me--I needed exhibits of a tracheostomy, a coronary artery
bypass and a deep vein thrombosis--all in time for a for-trial video
deposition the next day. The Doe Report had each exhibit on line. In
addition, I ran across an exhibit I hadn't even thought of: reduced ejection
fraction after a heart attack. Because this was a video deposition, I could
use the e-mail version of the medical exhibit, print it on my color copier,
and let the camera zoom in. For $400, less than one blow-up by one of The
Doe Report's competitors, I got four first-rate exhibits in less than a day.
The Doe Report saved me time and money."
"This past year, your company prepared three medical illustrations for our cases; two in which we received six figure awards; one in which we received a substantial seven figure award. I believe in large part, the amounts obtained were due to the vivid illustrations of my clients' injuries and the impact on the finder of fact."

"We are extremely pleased with the quality of the medical exhibits and the
timely manner in which they were provided. I will certainly recommend
your company to my business associates who could benefit from your services.
Please tell Brian Wilson [Director of Content Development, Senior Medical
Illustrator] that he did an exceptional job on these exhibits."

"It is my experience that it's much more effective to show a jury what
happened than simply to tell a jury what happened. In this day and age where
people are used to getting information visually, through television and
other visual media, I would be at a disadvantage using only words.
I teach a Litigation Process class at the University of Baltimore Law Schooland use [Medical Legal Art's] animation in my class. Students always saythat they never really understood what happened to [to my client] until theysaw the animation.
Animations are powerful communication tools that should be used wheneverpossible to persuade juries."
