Shock 360J mono, 1st + sub. shocks.
CPR 30:2 ratio for 2 min. No check rhythm or pulse)
Rhythm check shock
Epi 1mgIV/IO q3-5 min. Or vasopressin 40UIV/IO, 1x in place of 1st or 2nd dose of epi.

Recent head trauma.
Traumatic CPR.
Suspected aortic dissection
stroke is suspected the single most important test for a stable patient presenting to the emergency department is:
Computed tomography (CT) of the head
A head Ct can diferinate what:
A hemoragic stroke from a ischemic stroke
Ischemic stroke is when:
Blood vessels supplying the brain is blocked
Hemorrhagic Stroke is when:
When a cerebral artery bursts
Thrombotic stroke charcteristics
Most common, due to narrowing of brain vessels, occurs due to lack of 02
Embolic Stroke charcteristics
Material from outside brain becomes lodged in brain, may be fat,air, plaque, lodged were arteries branch
2 types of heemorrhagic stroke
Subarachnoid hemorrhage and Intracerebral hemorrhage
Subarachnoid hemorrhage
rupture of an artery w/ bleeding onto the surface of the brain
Intracerebral Hemorrhage
Bleeding into the brain caused by hypertension ruptures small blood vesels in brain
Hemorrhage or no hemorrhage TX:
Yes: Pt is not a candidate for fibrinolytic surgerey
NO: Pt may be a cadidate for fibrinolytic

3 hours
Indications for cardiac pacing include
Hemodynamically unstable bradycardia.
Bradycardia with ventricular escape beats.
Some cases of asystole.
Tachycardia with symptoms due to the fast rate is discovered: Start the Secondary ABCDs with emphasis on oxygenation, IV, VS, and EKG, and consider the following questions:
Stable, Narrow, Regualr
SVT, then V-A-C

Vagal maneuvers, if this fails..

Adenosine 6mg rapid IV push
repeat x2, q1-2min. at 12mg)

Cardizem (diltiazem) managed by an expert if
stable, narrow, regular tachyarrhythmia continues
When due you consult an expert
Tachycardia with symptoms due to the fast rate. That have QRS that are Narrow and Regular
When due you not consult a expert on tachycardia with symptoms due to the fast rate.
Unstable person you electrical cardiovert

Oh Say It Isn't So
Bradycardia Algorithm mnemonic
Pacing Always Ends Danger
Ventricular Fibrillation (VF)/
Pulseless Ventricular Tachycardia (PVT) Algorithm mnemonic
SCREAM mnemonic stands for
S Shock 360J* monophasic, 1st and subsequent shocks.
(Shock every 2 min.)
C CPR After shock, chest compressions respirations (30:2 ratio) for 2 min.
(Do not check rhythm or pulse)
R Rhythm check after 2 min of CPR (and after every 2 min of CPR thereafter) shock again if indicated. Check pulse only if an organized or non-shockable rhythm is present.
ment the Secondary ABCD Survey. Continue this algorithm if indicated. Give drugs during CPR before or after shocking. Minimize interruptions in chest compressions to <10 seconds.
E Epinephrine 1 mg IV/IO q3-5 min. Or vasopressin 40 U IV/IO, once, in place of the 1st or 2nd dose of epi.
A Antiarrhythmic
M Medications
Amiodarone 300mg IV/IO, may repeat 1 150mg in 3-5 min. if VF/PVT persists or
Lidocaine 1.0-1.5 mg/kg IV/IO, may repeat X 2, q5-10 min. at 0.5-0.75 mg/kg, (3mg/kg max. loading dose) if VF/PVT persists,or
Magnesium Sulfate1-2 g IV/IO diluted in 10mL D5W
(5-20 min. push) for torsades
With Automated External Defibrillation(AED):
Deliver no more than three shocks in a hypothermia patient.
If a patient develops V-fib during synchronized electrical cardioversion:
Switch off synchronization mode and defibrillate at 200J (or biphasic energy equivalent).
An oropharyngeal airway may:
Not be used in a conscious patient.
Cause airway obstruction.
Prevent a patient from biting and occluding an ET tube.
Be inserted "upside down" into the mouth opening and then rotated into
Endotracheal intubation:
Reduces the risk of aspiration of gastric contents.
When giving bag-valve mask ventilation what will prvent gastric inflation:
Cricoid pressure may prevent gastric inflation during ventilations.
Tracheobronchial suctioning points
Can result in hypoxemia.
Can cause bradycardia or arrhythmias
Should last no longer than 15 seconds.
Should be preceded and followed by hyperventilation with 100% oxygen.
An esophageal obturator airway (EOA):
Should not be used with a conscious person, pediatric patients, or patients who have swallowed caustic substances.
Mouth-to-mask ventilation has the following advantages:
It can be used with an oropharyngeal airway in place.
When correctly used it can effectively ventilate a patient.
It can deliver greater tidal volumes than bag-valve mask.
Supplemental oxygen can be administered during its use.
Increase cardiac output you can:
Increase heart rate and stroke volume
