When treating hypovolemic shock, never attempt to treat low BP with vasoconstrictor. True or False?
True. Without enough volume in the vessels to keep them open, a vasoconstrictor could close them completely .
What is the deffination of shock?
Inadiquate tissue perfusion: Not enough O2 and nutrients to tissues and not enough waste products transported away from tissues.
Early signs of shock are:
Changing LOC (anxious, scared, confused, disoriented), Thirst, Tachycardia, cool-pale-diaphoretic skin, tachypnea, normal to slightly elevated BP.
Late signs of shock are:
Falling BP, bradycardia due to the heart tiring and/or supply of catecholamines exhausted, Decreased respirations, decreased LOC due to cerebral hypoxia, cyanosis from deoxygenated blood pooling in the extremities.
Special considerations for shock assessment:
Age, hypothermia, pacemakers not compinsating, vasodilators such as alcohol consumption, hypertension, beta blockers.
Blood loss, plasma loss and water loss can all result in what type of shock?
hypovolemic shock.
When the heart loses the ability to pump enough blood with sufficient force to maintain adequate tissue perfusion (mechanical) or an obstruction to blood flow occurs can lead to (blank) shock.
Mechanical cause for cardiogenic shock are...
AMI, left ventricular failure (CHF), arrhythmias, cardiomyopathy, cardiac contusion.
Treatment for mechanical cardiogenic shock are:
Treat the rate, rhythm, and THEN use dopamine or levophed.
What form of cardiogenic shock results from pulmonary embolism, cardiac tamponade, tension pheumothorax?
Obstructive cardiogenic shock
Massive peripheral vasodilagtion resulting in a drop in BP and a relative hypovolemia, resulting in cardiovascular/circulatory collapse is what type of shock?
Low resistance shock aka "distributive shock"
Causes for neurogenic shock are:
spinal cord injury/severance, vasovagal episode.
Specific S/S of neurogenic shock include:
Low BP and relative bradycardia, warm dry skin, priapism and paralysis.
Cut thoracic spinal cord causes what heart rate?
Endotoxins (poisons) released by bacteria cause vasodilation and damage to capillary walls which allows plasma to leak out of the vascular space causes what type of shock?
Septic shock is often seen in patients with....
cancer, HIV, elderly, diabetics, and chronic diseases.
The most common causes for septic shock are:
UTI and pneumonia
No fever and dilated vessels is what stage of septic shock? (late or early)
late; in late stages of septic shock, the fever subsides.
What is the EMS treatment for septic shock.
IV fluid bolus and transport.
Vasodilation, increased capillary permeability, and bronchospasms caused by histamine released as a result of antigens introduced into the system is what type of shock?
anaphylactic shock
What does SIRS stand for?
system inflamitory response syndrome.
