Q

Why is excessive ventilation bad?

A

increases intrathoracic pressure, decreases venous return to the heart, and diminishes cardiac output. It may also cause gastric inflation and predispose the patient to vomiting and aspiration of gastric contents.

Q

What is the purpose of defibrillation?

A

Defibrillation does not restart the heart. Defibrillation stuns the heart and briefly terminates all electrical activity. If the heart is still viable, its normal pacemaker may resume electrical activity (return of spontaneous rhythm) that ultimately results in a perfusing rhythm.

25
reversible causes of cardiac arrest (5H5T)
hypovolemia: fluids (and oxygen and vent if hypoxic too) hypoxia: oxygen and ventilation hydrogen ion (acidosis): oxygen and vent hypo/hyperkalemia: tall peaked T wave vs flat T wave hypo/hyperthermia hypoglycemia: check sugars once vascular access Tension pneumo tamponade tablets/toxins Thrombosis pulmonary: get an early 12 lead Thrombosis coronary: get an early 12 lead
26
What PETCO2 indicates ROSC?
>40 mm Hg
27
Biphasic Shock Energy
first shock should be 120-200J, use maximum available. Subsequent shocks should be equivalent and higher doses may be considered
28
Monophasic shock energy
360J
29
If the initial shock terminates VF, but the arrhythmia recurs later in the resuscitation attempt, what shock strength do you then deliver?
the shock strength previously successful
30
how many cycles of CPR are typically performed in two minutes?
5 cycles
31
If a nonshockable rhythm is present and the rhythm is organized, what do you do next?
check for a pulse. If there is any doubt about the presence of a pulse, resume CPR immediately, consider EPI 1 mg and investigate need for advanced airway. If there is a pulse with an organized rhythm, proceed to post cardiac care
32
What if amiodarone is unavailable during a persistent VF/ pulseless VT code?
use lidocaine 1-1.5 mg/kg IV/IO first dose, then 0.5-0.75 mg/kg IV/IO at 5-10 minute intervals. Max dose of 3 mg/kg
33
Torsades des pointes (long QT interval)
mag sulfate 1-2 g IV/IO diluted in 10 mL D5W or NS over 5-20 mins if asymptomatic. If symptomatic, defib at 200J
34
Central Venous Oxygen Saturation (SCVO2)
should be 60-80%; if less than 30%, try to improve compressions and vasopressor (EPI) therapy
35
the typical dose of drugs delivered via endotracheal tube is
2-2.5 times greater than the IV route dose. DIlute the doses in 5-10 mL of sterile water or NS
36
what do you do after each peripheral dose of a rescue med is delivered?
flush with 20 mL NS and elevate extremity for 10 seconds.
37
diminished/absent lung sounds; look at chest rise: is it symmetric or asymetric? Person venting should say, "Im meeting resistance."
tension pneumo: tracheal deviation are late/ominous signs
38
no reversal agents for
meth and cocaine
39
3 attempts at a PIV within 90 s
if unsuccessful, go to IO
40
IO is designed for
short duration-only 24 hours
41
hesitate to run what through an IO?
adenosine: half life is too short. If IO is in LE, it wont be active by the time the drug circulates to the heart.
42
0.5 mg with a max of 3 mg for bradycardia
atropine for bradycardia: reassess q 3-5 mins; consider pacing or dopamine or EPI infusion (EPI 2-10 mcg for initial dose. Dopamine is weight-based 2-10 mcg/kg/min)
43
sinus tachy 100-150 bpm
treat underlying causes, but not the rhythm
44
Vtach
tombstone. No vagals. regular/monomorphic: give 6 mg adenosine (if it works, SVT with a aberancy) If that doesn't work, try amiodarone drip 150 mg over 10 min follow by maintenance infusion of 1mg/min for first 6 hours. If symptoms appear--> cardioversion.
45
5 things that can make a person SYMPTOMMATIC
``` chest pain diaphoresis SOB altered LOC hypotension ```
46
narrow
QRS complex less than 3 boxes (.12mm); indicates an atrial issue
47
wide
QRS complex greater than .12 mm. wide indicates a vertricular issue
48
unstable AF
monophasic cardiovert @ 200 J
49
unstable monomorphic VT
monophasic cardiovert @ 100 J
50
Other unstable SVT/Atrial flutter
monophasic cardiovert @ 50-100 J
51
polymorphic VT
monophasic debrillate
52
no adenosine for
patients with a Hx of asthma
53
Post cardiac arrest care (what you do once you have ROSC)
``` optimize hemodynamic and vent status initiate therapeutic hypothermia provide immediate PCI for coronary reperfusion (STEMI or AMI) institute glycemic control provide neuro interventions ```
54
how do you induce hypothermia?
use 4 degree C fluids such as LR or NS
55
what is the EPI flow rate for treating hypotension once you have ROSC?
0.1-0.5 mcg/kg/min titrated to SBP >90 mm Hg or MAP > 65
56
what is dopamine flow rate for treating hypotension on you have ROSC?
5-10 mcg/kg/min until 90>SBP or MAP >65
57
What is NE flow rate for treating hypotension if you have ROSC?
0.1-0.5 mcg/kg/min until SBP > 90 or MAP > 65
58
Once you have ROSC, and your patient fails to follow commands, the HCP should consider implementing
therapeutic hypothermia to protect the brain and other organs. Target temp is 32-34 degrees C for 12-24 hours.
