Hypovolemic schock - ANSWER ✔✔decreased circulating blood
volume (dehydration/trauma)
distributive shock - ANSWER ✔✔inadequate disruption of blood, so
that the blood flow is insufficient for the oxygenation of the tissues.
(anaphylaxis/sepsis/neurogenic)
cardiogenic shock - ANSWER ✔✔circulatory failure due to poor heart
function (cardiomyopathy/myocarditis/cardiac surgery)
, obstructive shock - ANSWER ✔✔circulatory failure due to obstruction
of blood flow to/from the heart (tension pneumothorax/cardiac
tamponade)
Dissociative Shock - ANSWER ✔✔insufficient oxygen carrying
capacity of the blood (anaemia/carbon monoxide poisoning)
Weight Estimation - ANSWER ✔✔weight (kg) = (age in years +4) x2
cardiac output - ANSWER ✔✔Cardiac output = heart rate x stroke
volume (blood volume ejected each contraction)
blood pressure - ANSWER ✔✔blood pressure = cardiac output X
systemic vascular resistance
compensation mechanism in shock - ANSWER ✔✔Tachycardia,
vasoconstriction, increased myocardial contractibility
Sizing of oropharyngeal airway - ANSWER ✔✔laid against the side of
the face, has a length equal to the distance between the level of the
patients incisors (or where they will be) to the angle of the jaw
sizing nasopharyngeal airway - ANSWER ✔✔depth - from the nostril
to the angle of the mandible.
diameter - shouldn't blanch the nostril
