Shock + Flashcards
components of stroke volume
Preload, Myocardial contractility, Afterload
Venous capacitance, Volume status, Venous flow
- Preload
- Myocardial contractility
- Afterload
- Preload
Mean venous systemic pressure- right atrial pressure
- Preload
- Myocardial contractility
- Afterload
- Preload
Peripheral vascular resistance
- Preload
- Myocardial contractility
- Afterload
- Afterload
in shock blood flow is preserved to
kidneys, heart and brain
progression of vasoconstriction in shock
Progressive vasoconstriction of cutaneous, muscular and visceral circulation
Poorly oxygenated cells will shift to anaerobic metabolism, hence formation of
lactic acid leading to metabolic acidosis
most common type of shock
HEMORRHAGIC SHOCK
suspect blunt cardiac injury in rapid deceleration
a. Cardiogenic
b. Cardiac tamponade
c. Tension pneumothorax
d. Neurogenic shock
e. Septic shock
a. Cardiogenic
tachycardia, Becks triad, insufficient response to fluid
a. Cardiogenic
b. Cardiac tamponade
c. Tension pneumothorax
d. Neurogenic shock
e. Septic shock

acute respiratory distress, subcutaneous emphysema, absent unilateral breath sounds, hyperesonance in percussion and tracheal shift
a. Cardiogenic
b. Cardiac tamponade
c. Tension pneumothorax
d. Neurogenic shock

c. Tension pneumothorax
brainstem injuries; hypotension without tachycardia and cutaneous vasoconstriction
a. Cardiogenic
b. Cardiac tamponade
c. Tension pneumothorax
d. Neurogenic shock
e. Septic shock
d. Neurogenic shock
can occur in patient’s arrival to ED is delayed for several hours
a. Cardiogenic
b. Cardiac tamponade
c. Tension pneumothorax
d. Neurogenic shock
