Heart - lung machine > period at which the heart stops > the machine assumes the functions of the heart > building the machine that can replace the function of your organs, even temporarily during an operation
EKG/ECG > Looks inside your body, rather than by forming an image, you put electrodes on the surface of the body > electrical signal reflects things happening deeper inside > you can detect the electrical activity of the heart and record it > look at the function of a heart in a living person
A machine that works well + A physician > diagnose a lot about the heart
Take cells > Keep isolated cells alive > Cell culture technology
Cells from skin/blood/bone marrow > keep them alive and in culture allows us to learn about human cells
Keep them alive + REPLICATE > skin + replicate > many skin cells
Propagated cells outside body and creating tissues > tissue engineered skin
Fully implantable artificial heart > Kentucky man stayed alive for a while
Gene chip > incubate a small sample of fluid on a gene chip where each dot represents a gene, you can see which genes are being expressed and which genes are not being expressed. Lets you do a profile of which genes are being used to make proteins
What do airplanes have to do with biomedical engineering? Technologies like airplanes are integral parts of medicine. Organ transplants. Jets are important in connecting donors to recipients. Get the organ from one place to another fast. What if we could develop ways to extend the life of an organ? That would open up more possibilities. Or what if we could avoid organ transplants altogether? What if we could grow organs from cells?
Contact lenses! New materials > there are not many things you would want to put into your eye. What makes it so safe? How are biomaterials designed and tested?
Artificial hip! Humans are physical objects living in a gravitational field. If you have hip pain, and if you can’t stand up against the gravitational field > how would you design replacement parts for joints like the hip?
Gibbs free energy > Gibbs is the father of modern physical chemistry
Human life expectancy increasing. Why are people living so long? Why do people die?
Penicillin > making products in the quantities that is needed, make it cheap and in abundance > the work of bioengineering > Take innovation and science like drugs and make them useful
Cancer wasn’t even on the charts in 1665 > multiple reasons
