The most revelant thing that I lenraed from chapter six was the part about blood pressure. I have never really understood how the nurses or doctors got those numbers and what they even meant. I work in admissions at the hospital and most of the time I am working in the ER. I can't even count how many times a patient will come up to me and tell me what their blood pressure is and all I could do was stare at them cause I had no idea. I did however ask one of the nurses in the ER about blood pressure and he told me that not only do you have to make sure the systolic pressure and/or the diastolic pressure are not too high or too low you have to make sure that two numbers aren't too close or too far away either.The other thing that was very interesting to me was what actual shock was. I have always known that shock wasn't a good thing but I didn't know that is was where the blood pressure dropped way low. And I didn't know that there were other ways of going into shock other than having been through trauma. Oh and I also realized that Atheroslerosis really grosses me out. Just picturing the arteries clogged with hardening fatty material is just gross. I'm am so glad that I rarely eat at fast food restaurants.
