RE: Discussion Week 6
COLLAPSE
What causes circulatory shock? Provide an example. What happens to the body during shock? How does the body return to homeostasis?
Professor and class,
Our text book, defines circulatory shock as any state in which cardiac output is insufficient to meet the bodys metabolic needs. There are two categories of circulatory shock, cardiogenic shock, and low venous return (LVR) shock. Cardiogenic shock means the heart does not pump sufficiently, mostly due to a myocardial infarction. Low venous return shock is caused by not enough blood returning to the heart, also known as low cardiac output.
Low venous return shock has three principal forms, hypovolemic shock, obstructed venous return shock and venous pooling shock. Hypovolemic shock commonly caused by hemorrhage or loss of blood volume due to dehydration, burns, bleeding ulcers and trauma. Death from heat exposure usually caused by dehydration. The body excretes as little as one point five liters (1.5L) of sweat per hour. Tissue fluid is lost, and water is replaced by the water in the blood stream. When this happens, blood volume decreases and can drop below an adequate amount for circulation.
Obstructed venous return shock happens when a vein is compressed and restricts blood flow usually caused by a growing tumor or aneurysm. Venous pooling shock happens when blood accumulates in the lower body, a result of standing or sitting for long periods of time or widespread vasodilation. Vessels dilate from sudden onset of loss of vasomotor tone, this is called neurogenic shock. Vasodilation and accelerated capillary permeability triggered by bacterial toxins cause septic shock. Anaphylactic shock causes the release of histamine, generalized vasodilation, and accelerated capillary permeability, a severe immune response to an antigen.
During circulatory shock, the body compensates and restricts blood flow to the extremities, decreased blood flow to the brain may cause loss of consciousness or confusion, blood pressure decreases, the pulse slows down, diaphoretic skin, and hyperventilation.
Homeostasis is restored by restoring blood flow and protecting the organs with treatments that may include prescription medication, cardiac procedures, or medical devices. Medications used to treat shock included anti-arrhythmias, antiplatelets or blood thinners and vasopressors and inotropes. Cardiac procedures include percutaneous cardiac intervention also known as cardiac stent and coronary artery bypass grafting. Sometimes a medical device is needed to restore and or maintain blood flow. These devices include extracorporeal membrane oxygenation, this circulates and oxygenates blood, an intra-aortic balloon pump that is placed in the aorta and the percutaneous circulatory assist devices, this includes the ventricular assist device.
The Discussion Board Guidelines are below. Be sure to read the rubric. Please check this! Its our way of telling you how to best succeed. For now, use the info below to guide you.
Post your answer on a specific topic to one of the questions. This is due by Wednesday night. You then need to respond to a classmate. Your response needs to be made on a dffierent day than the answer to the question. Therefore, your posts needs to be made on 2 different days of the week. You will not receive full credit if you post both comment to your classmates and answer my questions on the same day.
Here are some key phrases from the AP DB rubric about high quality posts:
indicate your mastery of the materials
integrate multiple views
present a seed for reflection
provide evidence that you are reading, comprehending the assigned materials and other student postings
giving thoughtful consideration to the assigned materials and other student postings
able to analyze them [the facts] and handle conceptual ideas
Be sure to either repeat the question to which you are responding or to include mention of the topic of the question in the first sentence of your post. This allows others to orient themselves to your response. Also, as you are answering the question, please address the person you are answer. For instance, when answering one of the question sets, address your answer to the instructor (and your class). When you are posting a comment to your classmates, include your classmates name in your post so that they will know you are providing more information about their topic. This will also help me to determine whether you are answering one of the questions in the question set, or making a comment to your classmates postings.
Important! Remember to read all new posts before submitting your answers. Repeated answers/topics will not count as a post. It is best to make a list of the topics as you are reading each other’s posts so that you are not repeating posts when you submit your answers.
Your posts should be a paragraph in length (minimum of 300 words). This does not include the question, quoted material, in-text/end-of-text citations, or statements that say “I agree, great job, I learned a lot or similar language” when commenting on your classmates posts. Short posts will not receive full credit. The discussions can incorporate material from the book as well as outside sources. When copying material for the text or outside sources (make sure it is in quotation marks), it does not count as part of the minimum length.
Remember that, in addition to your post answering one of my questions, you must respond to at least one other students post by the same set of guidelines.
When responding to someones post, remember to do more than just say: I agree or thats great. Extend the discussion by bringing in a different example, asking a question, providing additional details, disorders, diseases, debating, and/or connecting their response to a question you chose to answer.
Keep in mind that in science we seldom use quotations. The best way to determine if you understand something is to explain it to someone else in your own words.
All posts will be run through SafeAssign/TurnItIn, which is plagiarism detection software, per department regulations. You cannot reuse previous posts you have written from a prior semester. Evidence of plagiarism will result in a zero for the assignment. Repeated violations result in referral to the Academic Integrity committee.
Be sure to cite the source of your information when posting. Your citations can be at the end of your post. In-text citations do not count towards your word length.
This is necessary even if you are not directly quoting someone. You must provide a reference for any idea that is not your own, and for any information that is not common knowledge, even if you have put them in your own words.
Some internet resources are not acceptable. These include any web address that includes about.com, answers.com, wisegeek.com or Wikipedia.org anywhere in the URL. I will make a comment in your posts if the citation is unacceptable. Repeated uses from the same website will result in point deductions.
If you use a source other than your text, be sure to include the entire reference. If it is a website, when I click on the link, it should bring me to the exact page in which you obtained the information. You can do this by copying the entire http:// line.
To help keep track of your sources, it helps to have a word file open while doing your research. Copy the URL and title of the page as you type notes. (This can also help with grammar and spelling if you use Word’s built-in checker.).
Spell-check your posts! You can spell check your posts easily within the DB reply window.
Read ALL the posts for the week, not just your own. The DB is meant to be a true class discussion, not simply something to check off your list for the week. The DB questions are a bit like review questions you might be given to answer before an exam. The benefit here is that you are working together to answer them! Our little learning community will sink or float based on how well we all paddle.
I know this is a long set of guidelines. But following it will ensure that you receive a good grade for your discussion posts. The discussion board makes up 10% of your overall course grade.
