You are called for a patient who has a stab wound to the left chest. EMS initially reported a pulse, but when you go to assess, the pulse is now gone. The causes of arrest that you should consider in this patient are tension pneumothorax, pericardial tamponade, hemorrhagic shock, air embolism.
True
Incomplete chest recoil during compressions causes reduced venous return, increased ICP, increased intrathoracic pressure and ultimately leads to reduced cerebral and cardiac perfusion.
True or False?
True

d) Epinephrine 1 mg IV
e) Magnesium 2 g IV
f) Amiodarone 300 mg IV
a) A, B, C assessment
c) Defibrillation at 120 J
d) Epinephrine 1 mg IV
e) Magnesium 2 g IV
Myocardial function may require up to 72 hours to return to baseline with return of circulation after cardiac arrest.

c) Cooling a patient to 33˚C has been shown to improve neurological status post-arrest.
d) Cerebral autoregulation is disrupted for hours to days following return of cerebral perfusion.
e) Current guidelines recommend maintaining normothermia post-arrest.
b) Neuronal damage continues for hours or days following return of cerebral perfusion.
d) Cerebral autoregulation is disrupted for hours to days following return of cerebral perfusion.
