Describe the pathophysiology of organ damage that occurs in cardiac arrest
|
cessation of blood flow rapidly leads to cellular hypoxia and anaerobic metabolism
As toxic metabolites accumulate withing the cell a cascade of events potentiates tissue injury, including: Ca release, generation of free radicals and activation of catabolic enzymes |
|
|
survival after cardiac arrest from VF or VT decreases by how much for each minute a pt is not defibed
|
7-10%
|
|
|
properly performed CPR generates up to what % of baseline CO?
|
30%
properly performed CPR can produce a systolic BP of 60 mmHg and deliver a small but potentially life-sustaining amount of O2 and energy substrate to cerebral and myocardial tissues |
|
|
in an adult, how many compressions per minute should be performed? Depth of compression? compression to vent ratio?
|
100
2 inches 15:2 |
|
|
In adult cardiac arrest
What is the shock energy used? (monophasic) Epi dose? Amiodarone dose? (1st/2nd) |
Shock 360 J
Epi 1mg every 3-5 minutes Amiodarone: first dose 300 mg bolus; 2nd dose 150 mg |
|
|
reversible causes of cardiac arrest?
|
H&T
Hypovolemia Hypoxia Hydrogen ions (Acidosis) Hypo/hyper-kalemia hypothermia Tension pneumothroax Tamponade Toxins Thrombosis (pulmonary or coronary) |
|
|
immediately following all attempts at defibrillation what should be done?
|
5 cycles of CPR should be done BEFORE performing a pulse or rhythm check
