Shock is a medical emergency in which the organs and tissues of the body are not receiving a sufficient flow of blood. This deprives the organs and tissues of oxygen (which is carried in the blood) and allows the buildup of waste products. Shock can result in serious damage or even death. ("Shock," 2008)

Shock is usually caused by three major categories of problems: cardiogenic (problems associated with the heart), hypovolemic (total volume of blood available to circulate is low), and septic shock (infection in the blood). Cardiogenic shock can be caused by any disease which prevents the heart muscle from pumping strongly enough to circulate the blood normally. Heart attack, disturbances of the electrical rhythm of the heart, and any kind …show more content…

Septic shock can occur when an untreated or inadequately treated infection is allowed to grow in the body. Bacteria often produce toxins which can cause injury throughout the body. When large quantities of these bacteria, and the toxins, begin circulating in the bloodstream, every organ and tissue in the body is at risk of their damaging effects. "The most damaging consequences of these bacteria and toxins include poor functioning of the …show more content…

This allergic reaction can start within seconds of exposure, and rapidly develop to cause airway constriction, skin and intestinal irritation, and abnormal heart rhythms. An anaphylactic shock is caused by the release of histamine and other chemicals from mast cells. Mast cells are a type of white blood cell and they are found in tissues that regulate exchange with our environment. Mast cells have antibodies called IgE (immunoglobulin type E). IgE are made to detect environmental substances to which the immune system is sensitive. A substance that most people can tolerate, but others have an allergic response, is called an allergen. When IgE antibodies come together with allergens, they cause the mast cells to release histamine and other chemicals, which mix into all of the body's cells. This causes your body's vessels to leak fluid into surrounding tissues, causing the fluid accumulation, redness, and swelling. On smooth muscle cells of the airways and digestive system, they cause constriction. On nerve endings, they cause itching. (Molle, Durham, Kronenberger, & West-Stack, 2004)

In an anaphylactic shock, the life threatening response is due to extreme hypersensivity to the allergen. Exposure by ingestion, inhalation, or skin contact causes anaphylaxis. Specific causes are fish, shellfish, nuts, stings of bees, wasps, or hornets, vaccines, antibiotics, insulin, hormones, aspirin and latex.

    Acute respiratory distress syndrome (ARDS) is a condition where there is a low oxygen level in the blood this mostly affects the lungs, people who have sepsis will be affected by ARDS as there breathing rate will decrease. Another reason for a multi-organ dysfunctions is that there is a lack of blood being given to the organs this causes low blood pressure or as it’s called hypotension this mostly affects diabetic people which leads them to having sepsis. Also hypoxia which is a lack of oxygen is another pathological physiological outcome of sepsis as less oxygen is reaching the tissue this is due to the fact that there is less oxygen in the blood. This causes confusion and change in heart and breathing rate which can lead to

For comparison there are 180,000 deaths a year from heart attacks and 200,000 deaths a year from lung or breast cancer (Nguyen et al). When compared to the numbers for diseases that are talked about every day, it is staggering the impact that sepsis has. Not only is it a lethal disease but it is costly as well.

    Antimicrobial therapy is the cornerstone sepsis treatment, and the therapeutic goal should be centered around administration of effective IV antibiotics within 60 minutes of septic shock or severe sepsis (without shock) recognition. The initial antimicrobial therapy should be empiric and focused on having activity against all expected pathogens (bacterial, fungal, viral), based on each individual patient situation. Daily reassessment of antimicrobial therapy should be performed, with de escalation in mind; procalcitonin levels can be of use to direct discontinuation in patients with no evidence of infection following initial septic

    Septic shock is a condition and/or state of hypoperfusion that derives from another condition called sepsis; Sepsis the infection of the bloodstream. In order to acquire septic shock one must obtain an infection of the bloodstream. Any type of pathogen can cause that infection. The main factor is bacteria and while fungi and viruses have been known to be able to cause septic shock the occurrence is much more rare than through bacteria.The cause of septic shock lies within

    ... immune system. The body’s immune system is beneficial to rid of illness and foreign invader our body note to be a threat such as parasite, virus, or bacteria but sometimes it can also reacts to a harmless substance. As a result to protect out immune system, the body manufacture a protective protein barrier called antibodies. This protective agent exhibit swelling and inflammation of tissues whenever an allergic reaction occurs as a response to eliminate the threat (Burks, Harthoorn,Van Ampting, Oude Nijhuis, Langford, Wopereis, & Harvey, 2015). In addition, the anatomical systems of babies are still developing in the sense that, they have small, sensitive airways in their lungs. In a situation of allergy contact, the airways become swollen as a result to rid virus and bacteria; and in response, babies start to cough, sneeze and can progress to wheezing and asthma.

    Power can be defined as the ability to influence or outright control the behavior of people. A variety of different things can drive power, including both knowledge and experience. Power in most cases is needed to establish authority. In today’s country, the United States government has a lot of power. It has so much power that even American citizens are beginning to complain about it. Having all this power and authority has allowed the government to make decisions quicker. However, by making decisions faster, some mistakes can be made and innocent people can be convicted. This point is directly exemplified when using two New Yorker articles, “Surviving Solitary” and ‘A Shot to The Heart.” Both articles consist of results produced quite

    Anaphylaxis shock occurs when someone who is sensitive to a substance they are exposed to which results in constricted airway and possible inability to breathe. Parents with children that experience any form of allergic reaction most notify the day care provider so appropriate precautionary steps are taken to maintain a safe health environment for these children. As allergy conditions have slowly increased within our society day care providers have taken more aggressive action to protect these children by extending a “peanut free environment” within the school setting. The percentage of children who experience their first allergic reaction outside the home has increased by 77% over past years daycare providers need to be trained and prepared to handle all types of allergic reaction situations. Steps that a provider and parent should take are as follows: 1. Food allergy action plan, 2. Inform all staff, 3. Post child’s name and allergy,

    Capriotti & Frizzell (2016) explain that sepsis is often seen in those who have a weak immune system. These individuals are at an increased risk of developing sepsis from microorganisms that a healthy immune system would normally fight off (Capriotti et al. 2016). The elderly, infants, and immunosuppressed patients are the most at risk for developing the condition (Capriotti et al. 2016). Sepsis can be caused by any microbe, but is most often caused by bacteria (Capriotti et al. 2016). Since sepsis has such a broad reach and can develop as a secondary infection after an initial injury or illness, Capriotti & Frizzell (2016) further explain the di...

  • Pathophysiology of Sepsis Inflammatory Response

    987 Words  | 2 Pages

    Sepsis is defined as an exaggerated, overwhelming and uncontrolled systemic inflammatory response to an initially localised infection or tissue injury, which may lead to severe sepsis and septic shock if left untreated (Daniels, 2009; Robson & Daniels, 2013; Dellinger et al, 2013; Perman, Goyal & Gaieski, 2012; Vanzant & Schmelzer, 2011). Septic shock can be classified by acute circulatory failure as a result of massive vasodilation, increased capillary permeability and decreased vascular resistance in the body, causing refractory hypotension despite adequate fluid resuscitation. This leads to irreversible tissue ischaemia, end organ failure and ultimately, death (McClelland & Moxon, 2014; Sagy, Al-Qaqaa & Kim, 2013, Dellinger et al, 2013).

    Sepsis is defined as a systemic inflammatory response caused by an infective process such as viral, bacterial or fungal (Holling, 2011). Assessment on a patient and starting treatment for sepsis is based on identifying several factors including the infective source, antibiotic administration and fluid replacement (Bailey, 2013). Because time is critical any delay in identifying patients with sepsis will have a negatively affect the patients’ outcome. Many studies have concluded every hour in delay of treatment mortality is increased by 7% (Bailey, 2013). Within this assignment I will briefly discuss the previous practice and the recent practice including the study based on sepsis. I will show what enabled practice to change and I will use the two comparisons of current practice and best practice.

So when doing initial assessment it is important to check for serious injuries and if any are found, it should be assumed that he or she is at risk of shock.2 First stage some early signs of shock include anxiety, restlessness and fear, along with rapid heart rate and increased breathing. During the second stage mental statues continues to decline therefore confusion arises, sleepiness and disorientation.2 When a victim is in shock, it is important to prevent hypothermia by using blankets and keeping his or her body temperature warm.2 It is important to remember that shock is irreversible unless provided professional medical help. Calling for the emergency gives the victim a higher chance of survival, the victim could potentially “receive help before shock leads to death”.2

    Patients who usually have allergies suffer from many symptoms due to the allergic reaction(s). Normally, your immune system protects you against invading agents such as bacteria and viruses. Otherwise harmless allergens (allergy-producing substances) cause your body to react as if they were dangerous invaders. In effect, your immune system is responding to a false alarm.
