Shock develops as a consequence what three events: - (1) blood volume decreases (2) the heart fails as an effective pump (3) peripheral blood vessels massively dilate Name the four main categories of shock – Hypovolemic Distributive Obstructive Cardiogenic What is hypovolemic shock - Most common, volume of extra cellular fluid is significantly decrease due to loss or decrease in blood or plasma What is distributive shock - Fluid circulation doesn't permit effective perfusion What is neurogenic shock - Rare, injury that affects the basal motor center the medulla or peripheral nerves from spinal cord What is septic shock - Highest mortality rate associated with overwhelming bacterial infections Name the signs and symptoms of septic shock that are not present in other forms of shock – Increased WBC countFever Tachycardia Warm flushed skin What is anaphylactic reaction - Severe allergic reaction What is obstructive shock - Interference of blood circulation in or out of the heart What is cardiogenic shock? - Ineffective heart contractions Decreased cardiac output What are the three stages of shock - compensation, decompensation, irreversible What happens in the compensation stage - Body trying to stabilize itself What happens in the decompensation stage - Failure to self stabilize What happens in the irreversible stage of shock? - The patien is pretty much dead What happens to the systolic BP in impending shock? Actual shock? - 90-100 Lower than 80 What happens to the pulse pressure in shock - Narrows What happens to the pulse in shock - Weak and ThreadyWhat happens to the respirations in shock - Increases to help move blood to heart
