Correct!!
Hypoxemia - ANSWERThe most common cause of cardiopulmonary arrest in the trauma patient
Cardiac output - ANSWERHeart rate x stroke volume
Decompinsated shock - ANSWERHypotension, altered mental status, cardiac arrest
Early shock - ANSWERLoss of 15-25% of blood volume, tachy, pallor, narrowed pulse pressure, thirst,
weakness
Late shock - ANSWERLoss of 30-45% blood loss, hypotension. Bodies ability to compensate has failed
Shock - ANSWERCondition that occurs when perfussion of the bodies tissues with oxygen, glucose,
electrolytes and fluid becomes inadequate.
Compensated shock - ANSWERWeakness, lightheaded, pallor, tachy, diaphoresis, tachypenia,
decreased urine output, weak peripheral pulses
Pressence of tachycardia - ANSWERTachycardia in the resting patient is always an indication
something medically wrong or possibly occult hemorhage.
Whats considered tachycardia? - ANSWERAbove 100 in an adult and higher in younger ages
Low volume shock - ANSWERabsolute hypovolemia, caused by a Weak, thready pulse,rapid
rate,hemorhage, or other major body fluid loss
High space shock - ANSWERrelative hypovolemia, caused by spinal injury, vasovagal syncope, sepsis
and certain drug overdoses, normal weak pulse
, Mechanical shock - ANSWERcardiogenic shock, also known as obstructive shock, caused by
pericardial tamponade, tension pneumothorax, massive pulmonary embolism, or weakened heart
muscle(like myocardial contusion or infarction)
whats the #1 cause of preventable death from injury? - ANSWERhemorrhagic shock
hypovolemic shock signs and symptoms - ANSWERtachycardia, pale, and have flat neck veins
"vasodilatory shock" - ANSWERrelative hypovolemia or high space shock
Neurogenic Shock signs and symptoms - ANSWERDecreased blood pressure, heart rate will be
normal or slow and the skin is usually warm, dry and pink. The patient may also have accompanying
parylisis and/or sensory deficits.
tension pneumothorax - ANSWERHigh air tension that may sometimes develop in the pleural space
between the lung and the chest wall. It prevents venous return to the heart causing JVD and tracheal
deviation
Cardiac tamponade or pericardial tamponade - ANSWERblood fills the space between the heart and
the pericardium squeezing the heart and preventing the heart from filling. Causes cardiac output to
fall resulting in shock.
"Becks Triad" - ANSWERsigns and symptoms of a pericardial tamponade: Shock, Muffled Heart Tones,
Narrowed Pulse Pressures and JVD. (Normal Lung sounds!)
Myocardial Contusion - ANSWERHeart loses pumping ability due to direct injury to the heart muscle
and cardiac dysrhythmias. Rapid Transport and cardiac monitoring!
for Cyanosis to occur - ANSWERa patient must have 5 grams of deoxygenated hemoglobin per 100cc
of blood
What is the optimal pulse oximetry reading for patients at risk of shock - ANSWER95%
What is the fluid bolus for a patient with shock symptoms? - ANSWER20 mL/KG IV
