 * 1) Find a peer-reviewed journal article on PubMed. Practice inserting your citation in the above space using the "cite" tool
 * 2) Choose one "B-level" medical article on Wikipedia from the following list: https://wp1.openzim.org/#/project/Medicine/articles?quality=B-Class&importance=High-Class
 * 3) Practice editing live on Wikipedia by finding a typo in the text or improving the clarity/readability of a sentence by adjusting a few words in a sentence.

Wikipedia Article Title: Cardiac Arrest

Proposed Changes (3 marks): “Signs & Symptoms” section

--

Cardiac arrest is not preceded by any warning symptoms in approximately 50 percent of people. For those who do experience symptoms, they will be non-specific. This can present in the form of new or worsening:


 * chest pain
 * fatigue
 * blackouts
 * dizziness
 * shortness of breath
 * weakness
 * vomiting

'''When cardiac arrest is suspected due to signs of unconsciousness or abnormal breathing, a bystander should attempt to feel a pulse for 10 seconds; if no pulse is felt, it should be assumed the victim is in cardiac arrest. As a result of loss of blood flow to the brain (cerebral perfusion)''', the victim will rapidly lose consciousness and can stop breathing. Near-death experiences are reported by 10 to 20 percent of people who survived cardiac arrest, which demonstrates a certain level of cognitive processes that are still active during resuscitation.

--

Rationale for proposed change (3 marks): The first sentence (bold) was added in order to provide clarity regarding the length of time a pulse should be palpated for on a victim of cardiac arrest. The original information in the article was ambiguous, stating that the “inability to feel a pulse” was indicative of probable cardiac arrest. In reality, based on higher level evidence and clinical guidelines, cardiac arrest victims may have a weak or thready pulse; however, monitoring the length of time between each pulse is necessary to identify the type of emergent cardiac event occurring. It is necessary to make this change, given that a reader may misinterpret this and perhaps assume that a victim with a very weak pulse (or long pause between each pulse) is not in cardiac arrest, and should not be treated accordingly. The information regarding feeling for a pulse for 10 seconds was taken from a recent clinical guideline published by the American Heart Association, which focused on cardiopulmonary resuscitation and emergency cardiovascular care (1).

Area of controversy (if applicable) (1 mark): There is variability in how cardiac arrest is initially identified. Some recent studies have identified that emergency dispatchers often call for bystanders to observe for signs of unconsciousness or abnormal breathing (2). Only a few sources elaborate on the further step to feel for a pulse for a duration of 10 seconds, and given that this extra step is oriented towards a layperson that would be present near the victim, adding this extra piece of information. Further, in setting a 10 second window during which pulse should be observed, the importance of not waiting too long before chest compressions is emphasized (1).

Critique of source (2 marks): The American Heart Association is governed by policies and procedures that minimize the risk of conflict of interest. However, the authors of the clinical practice guideline disclosed their affiliations with various institutions and companies, such as Stryker Corporation - a company specializing in medical technology and devices (1). This indicates that there may indeed be potential conflicts of interest at play that may ultimately have influenced guideline development. It is important to note that clinical practice guidelines, as a whole, are widely seen as the standard of care in treating many medical conditions, given that they are consensus and evidence-based, and are developed in consultation with numerous clinical experts in the field. One weakness of using clinical practice guidelines is that evidence is often drawn from homogenous patient populations that have similar presentations. However, we recognize that cardiac arrest victims may not always present with the same identifiable symptoms that include unconsciousness, abnormal breathing, and lack of pulse. Rare presentations of cardiac arrest may be excluded in our use of this source (3).

What to post on the Wikipedia article talk page (part of assignment 3)

 * This will also be covered on Nov 15th in class. Your group should use the below template to share an outline of your proposed improvements (including your new wording and citations). Article talk pages are not places to share your assignment answers. The Wikipedia community will be more interested in viewing your exact article improvement suggestions including where you plan to improve the article (which section), what wording you suggest, and the exact citation (Note: all citations must meet WP:MEDRS)
 * You will not be able to paste citations directly from your sandbox to talk pages (unless you are interested in editing/learning Wiki-code in the "source editing" mode). We suggest re-adding your citations on the talk page manually (using the cite button and populating the citation by pasting in the DOI, website, or PMID). You will have to repeat this process yet again when you edit the actual article live.
