Document Summary

Shock is a syndrome characterized by decreased issue perfusion and impaired cellular metabolism. Results in imbalance between supply of and demand for oxygen and nutrients. Cause, iniial presentaion, and management strategies of various types of shock difer, physiological responses of cell to hypoperfusion are similar. Just for discussion, shock is classiied as low blood low (cardiogenic and hypovolemic shock) or maldistribuion of blood low (sepic, anaphylacic, and neurogenic) Cardiogenic shock occurs when either systolic or diastolic dysfuncion of pumping acion of heart results in compromised cardiac output (co). Heart"s inability to pump blood forward is classiied as systolic dysfuncion. Systolic dysfuncion mostly afects let ventricle because systolic pressure and tension greater in let chambers of heart: when it afects right chambers of the heart, blood low through pulmonary circulaion is compromised, precipitaing causes of systolic dysfuncion incl. Mi, cardiomyopathies, blunt cardiac injury, severe systemic or pulmonary hypertension, and myocardial depression caused by metabolic problems.
