nugget of wisdom - shock
so...what exactly is shock?
yes yes, I know the S&S are weak rapid pulse, fast shallow breathing, cold clammy skin, yada yada....
but, what is shock??
shock, essentially is a life-threatening condition in which blood pressure is too low to sustain life.
Shock has several causes: a low blood volume, which causes hypovolemic shock; inadequate pumping action of the heart, which causes cardiogenic shock; or excessive widening of blood vessels, which causes distributive shock (anaphylactic shock, neurogenic shock and septic shock).
Hypovolemic Shock
Low blood volume results in less-than-normal amounts of blood entering the heart with every heartbeat and therefore less-than-normal amounts of blood being pumped out to the body and its cells.
Cardiogenic Shock
Cardiogenic Shock
Inadequate pumping action of the heart can also result in less-than-normal amounts of blood being pumped out with every heartbeat.
Distributive Shock
Distributive Shock
Excessive dilation of blood vessels (vasodilation) increases the capacity of blood vessels, so that blood meets with less resistance as it flows through them. Blood pressure in the dilated vessels is lower, so the cells fed by those vessels get less blood.
Blood vessels may be excessively dilated because of a serious allergic reaction (anaphylaxis (see Allergic Reactions: Anaphylactic Reactions)), a severe bacterial infection (shock caused by such an infection is called septic shock (see Bacteremia, Sepsis, and Septic Shock: Introduction)), overdose of drugs or poisons that dilate blood vessels, and injuries to the spinal cord and rarely the brain.

nugget of wisdom - cerebral compression
here's a simple, yet detailed explanation of how cerebral compression arises!
"Your brain takes up about eight/tenths of the space inside your skull. Most of the rest of the space is filled with blood vessels and cerebrospinal fluid (CSF), a dense, clear, colorless substance. CSF flows around the outside of the brain, through a latticework of fibers. Working together, fluid and fibers form the brain's primary shock absorption system, protecting the brain from the bumps and jiggles of everyday life. But, if your head smacks into something with sufficient force, your brain can slosh around enough to tear some of the blood vessels, and even bruise the brain itself, if it hits the inside of the skull. That's how you can have brain damage without headbone damage.
What happens inside the head is this. Blood flows out of the broken blood vessels in the head and, sometimes, blood serum starts to leak out of the vessels in the damaged area of the brain. Swelling results, but, unlike the rest of the body, there's no place for the swelling to go. As the space inside the head decreases, there is less and less room for the flow of life-sustaining blood. Initially, the brain stops making CSF, and starts to reabsorb what is already there . . . the brain tries to create more space. The brain can even limit the amount of blood flowing to itself. But, if the damage is sufficient, the brain's compensatory mechanisms cannot keep up with the swelling. Intracranial pressure (ICP) starts to rise, and, as a result, the brain is squashed."

tentative design for OCIP t-shirt
hey everyone!
below is the tentative design of the OCIP t-shirt that we will be selling for fundraising (yes, we have fundraising events!). take a look, and let me know what you think of the design! (vote on the poll on the right). think of it as you're a student, and another group is selling this t-shirt. will you get it at $8??
the design is commas (,) arranged in the form of a seedling. seedling symbolizes hope and growth, which encapsulates the essence of our project in helping the Cambodian children :) it'll be single color (white) printing in front, with no designs at the back (all t-shirts look like that nowadays!)

did you know..
that RVSJAB has obtained the Gold Award for Corps Achievement Award every single year since the award was introduced?
that's a whopping 11 consecutive years, and we're one of the only 3 Corps to do that ;)
damn, we're oh-so-zai.
