the difference between the systolic and diastolic pressures
pulse pressure
regulates the blood flow through the capillary beds

tissues start to die, affecting the body processes if these conditions aren’t promptly stopped and reversed, death will follow. what conditions are they talking about
conditions of shock
(pump failure) tension pneumothorax, cardiac tamponade, pulmonary embolism are types of
cardiogenic shock
(poor vessel function) septic shock, neurogenic shock anaphylactic shock psychogenic shock, are all types of
distributive shock
hemorrhagic shock and non-hemorrhagic shock are types of
hypovolemic shock
compensated shock
early state- when the body is still able to compensate
decompensated shock
when the body cant compensate and they vital signs change significantly (BP drops, fast HR, labored/irregular bleeding, weak pulse)
