My name is Caroline Gainer and I am addicted to the POC. In this case POC refers to Portable Oxygen Concentrator.
Everyone is addicted to oxygen. It is the element that is necessary for us to burn the food that we eat as fuel to get energy
to maintain life. It supports that process that we call respiration which is much more than just breathing in and breathing out. Respiration is the process by which we take in oxygen and burn sugar in the cells and give off carbon dioxide as a waste product. The carbon dioxide is the main gas given off when we exhale.
Those of us with COPD are obstructed from fully exhaling the carbon dioxide. This causes us to become short of breath because it is the level of carbon dioxide in our lungs and not oxygen that drives the need to inhale.

I am so glad that I was able to be of help.
My brother saved this weblog for me and I have been reading through it for the past couple hrs. This is really going to benefit me and my classmates for our class project. By the way, I like the way you write. http://www.piano.m106.com
As a former teacher it is music to my ears to say that my blog will help with your class project. Let me know what else I might do to help.
