NR 526-week 7 discussionWhen a patient goes into shock, health professionals have to quickly identify what type of shock
it is. Shock is a medical emergency and has five types. The five types of shock are neurogenic,
anaphylactic, septic, cardiogenic and hypovolemic. Anaphylactic shock has to do with a severe
allergic reaction. Septic shock deals more with infection in the body, in particular the
inflammatory response. A neurogenic shock deals with the heart and is caused by
vasodilation. Cardiogenic and hypovolemic shock are similar in nature in relation to how it
affects the cardiovascular system (Schub and March, 2018, p. 1). The table below compares and
contrasts cardiogenic and hypovolemic shock.
