- ANSPrehospital shock index pg. 85
Explain Hypovolemic Shock. - ANSMost common to affect a trauma pt cause by
hypovolemia.. Hypovolemia, a decrease in amount of circulating blood volume, may
result from significant loss of whole blood because of hemorrhage or from loss of
semipermeable integrity of cellular membrane leading to leakage of plasma and
protein from intravascular space to the interstitial space (as in a burn).
Some causes:
- Blood loss
- Burns, etc.
Explain Irreversible Shock. - ANSShock uncompensated or irreversible stages will
cause compromises to most body systems.
- Inadequate venous return
- inadequate cardiac filling
- decreased coronary artery perfusion
- Membranes of lysosomes breakdown within cells and release digestive enzymes
that cause intracellular damage.

Explain Obstructive Shock. - ANSResults from inadequate circulating blood volume
because of an obstruction or compression of great veins, aorta, pulmonary arteries,
or heart itself.
Some causes:
- Cardiac tamponade (may compress the heart during diastole to such and extent
that atria cannot adequately fill, leading to decreased stroke volume).
- Tension pneumothorax may lead to inadequate stroke volume by displacing inferior
vena cava and obstructing venous return to right atrium.
- Air embolus may lead to obstruction of pulmonary artery and subsequent
obstruction to right ventricular outflow during systole, with resulting obstructive
shock

Explain Pulmonary Response. - ANSTachypnea happens for 2 reasons:
1. Maintain acid-base balance
2. Maintain increased supply of oxygen
* Metabolic acidosis from anaerobic metabolism will be a stimulus for the lungs to
increase rate of ventilation. Increased RR is an attempt to correct acidosis +
augments oxygen supply to maximize oxygen delivery to alveoli.

fat embolism - ANSa pt has been in the ED for several hrs waiting to be admitted. He
sustained multiple rib fractures and a femur fracture after a fall. He has been awake,
alert, and complaining of leg pain. His wife reported that he suddenly became
anxious and confused. Upon reassessment, the pt is restless with respiratory
distress and petechiae to his neck. The pt is exhibiting s/sx most commonly
associated with which of the following conditions?
Flail chest - ANSParadoxical chest wall movement

finding in a pt with a tube thoracstomy connected to a chest drainage system?
from hemorrhage is leading cause. Hypovolemia is caused by decrease in the amount
of circulating volume. Goal is to replace volume. - ANSHypovolemic Shock
