| How hard and how fast should you push during CPR | greater than or = to 2 inches and =to or greater than 100 per minute |
| How do I remember V-tach | tombstones |
| Is V tach a shockable rhythm | yes |
| what is the shock energy using monophasic defibrillator | initial dose is 120-200 J then 2nd and subsequent doses should be equivalent/higher doses considered |
| what is the defibrillator monophasic shock energy level | 360 J |
| what drugs/doses can be used in VF/VT | epinephrine 1mg q 3-5 min amiodarone 300mg first dose 150 mg 2nd dose |
| what drug can be given at what dose place of epi during vt/v-fib | vasopressin(potent vasoconstrictor) 40U can replace 1st or second dose of epi |
| what are the 5 H's that may be correctable causes of cardiac arrest | hypovolemia hypoxia hydrogen ion (acidosis) hypothermia hyper/hypo kalemia |
| what are the five T's that may be correctable causes of cardiac arrest | tension pneumothorax tamponade,cardiac toxins thrombosis,pulmonary thrombosis,coronary |
| how often should you rotate compressors | q 2 minutes |
| WHAT IS THE COMPRESSION TO VENTILATION RATIO IN THE ABSCENCE OF AN ADVANCED AIRWAY | 30/2 |
| IS ASYSTOLE A SHOCKABLE RHYTHM | NO |
| WHAT IS THE ASYSTOLE/PEA ALGORITHM | CPR X 2 MIN IV/IO ACCESS EPI Q 3-5 MIN CONSIDER ADVANCED AIRWAY C CAPNOGRAPHY RECHECK RHYTHM IF NOT SHOCKABLE CONTINUE CPR AND REPEAT EPI |
| WHAT IS CONSIDERED A BRADYARRHYTHMIA AND WHAT SYMPTOMS INDICATE "SYMPTOMATIC" | HEART RATE TYPICALLY <50/MIN HYPOTENSIVE/FEELS FAINT COOL/CLAMMY/DIAPHORETIC CHANGE IN MS (MENTAL STATUS) |
| what drugs/dose are given in adult bradycardia | atropine iv dose 0.5mg bolus if atropine ineffective ****transcutaneous pacing***** dopamine IV 2-10mcg/kg/min epinephrine IV infusion 2-10mcg/min A.D.E. Consider expert consultation transvenous pacing |
| what is adult tachycardia with a pulse? | Tachycardia is a faster than normal heart rhythm that is usually classified as narrow complex (QRS < 0.12 seconds on ECG) or wide complex (QRS > 0.12 seconds on ECG). |
| what sx do unstable tachycardia cause | Unstable tachycardia will cause hypotension, altered level of consciousness, symptoms of shock or chest pain |
| what are the pulseless rhythms | pulseless vtach vfib pea asystole |
| what is the reason for using synchronized cardioversion and when is the electrical current activated? | Synchronization avoids the delivery of a LOW ENERGY shock during cardiac repolarization (t-wave). If the shock occurs on the t-wave (during repolarization), there is a high likelihood that the shock can precipitate VF (Ventricular Fibrillation). |
| What is the primary cause of V-Fib? What will V-Fib quickly evolve into? | The primary cause of VF is hypoxia (lack of oxygen) to the heart muscle which causes hyperirritability in the cardiac muscle tissue. |
| What are the core drugs/dosages given during VT/VF? | -epi 1mg q 3-5min -vasopressin 40U (can replace 1st or second dose of epi) -amiodarone 300mg (1st dose) 150mg(2nd dose) |
| What is the quickest way to confirm PEA? | Perform a pulse check (carotid or femoral) |
| What is the most common cause of PEA? | Hypovolemia |
| What is done during asystole? | CPR and Epi q 3-5 min |
