Breathable Liquid- Who Knew?

I just finished reading the Lost Symbol by Dan Brown. The book was interesting. It brought up several topics of debate: faith, religion, America's early history, scientific advancements, technology and family to say the least. However, it ended a little flat.

There is one concep
t which I found to be absolutely fascinating- Breathable Liquid. I did some research and this form of respiration has been in existence since the late 1960's. Mice were used initially in these experiments and were made to breathe in an oxygen rich saline solution. The mice would live for several weeks after exposure but then developed pulmonary complications. The saline solution did not aid in the extraction of carbon dioxide from the lungs, thus resulting in severe lung damage.

Thank goodness that by the time The Abyss was filmed in 1989, scientists had found perfluorocarbons. It helped to avoid nitrogen build up (or "The Bends") when deep sea diving. Although, these perfluorocarbons are harmful to the ozone layer, they effectively dissolve both oxygen and carbon dioxide. Today, this amazing fluid is being used in addition to respirators to help with acute respiratory problems and may one day replace blood transfusion. Cool huh?

For the Technologically Challenged . . . You are not alone.


Well, today was rather interesting. I really believe that there is some type of conspiracy where all technological devices are against me. First it was the Mac, that just did not want to communicate with my printer. I don't care if it was upset with the printer but I really needed to print some documents necessary for my job; my lesson plans.

Once I finally got the Mac and the printer to resolve their differences, the scanner began giving the silent treatment. I could not scan because the scan function on this all-in-one printer, was not communicating with the USB port. Now forgive my ignorance, but should it matter what USB port you connect the printer cable to. Well, I tried all of them to no avail.

Consequently, I abandoned the Mac and tried my PC laptop. It took me three hours just to download the driver software from the internet and install the flippin' thing on my PC. Then when I finally am able to scan the document, my PC alerted me to the fact that I had not installed the latest version of Adobe Acrobat Reader 9.2. Well excuse me. Adobe took approximately an hour and a half. It took me a total of 7 hours to scan one document. I am mentally, physically and emotionally exhausted.
