Cardiac Arrest Management Flashcards
5 principles of high quality CPR
1) optimum compression rate (100-120)
2) optimum compression depth (2 inches, 5 cm, 1/3 of chest)
3) complete chest recoil
4) optimum ventilation rate (1 breath every 6 seconds)
5) infrequent compression pauses
If no suspected treatable cause then:
Call EPOS after 30 mins of high quality CPR
6 steps in cardiac arrest chain of survival
1) activation of emergency services
2) high quality CPR
3) defibrillation
4) advanced resuscitation
5) post cardiac arrest care
6) recovery
3 classes of atraumatic death
1) coronary: ACS, spasm, embolism, congenital abnormalities
2) cardiac: valvular heart disease, cardiomyopathy, pericardial disease
3) non cardiac: pulmonary embolism, vascular dissection / rupture, intracranial bleed
Treatable causes (5 H’s 5 T’s)
Hypoxia, H acidosis, hypothermia, hyperkalemia, hypovolemia
Toxins, tamponade (cardiac), tension pneumothorax, thrombosis (cardiac), thrombosis (pulmonary)
